Besides Ni, Co, Cr, Fe, Cu, V and W the catalysts contain active carbon. The action of active carbon is reduced to creation of a highly developed catalyst surface. The catalysts are active in hydrogen sulfide oxidation up to elementary sulfur already at 20-80 ° C. Aluminium oxide and chromium oxide base catalysts manifest the highest activity. Increase in the temperature above 60 ° C decreases the catalysts do not manifest activity as regards hydrogen sulfide 3.FORMATION OF AMMONIUM THIOCYANATE IN THE OXIDATIVE PURIFICATION OF COKE OVEN GAS. Panferova, D.; Lebedeva, G.N.; Peskova, D.V.; Maiskaya, G.G. Source: Coke & Chemistry (USSR), n 5, p 46-50, 1985 Abstract: The authors present the results of a study of the kinetics of reaction of the polysulfides produced in the dissolution of sulfur and in the oxidation of sulfide in the ammonium thiocyanate formation reaction. The experiments were conducted in a static system. It is shown that polysulfides obtained by oxidation of ammonium sulfate in the presence of catalyst have greater reactivity for cyanide ions than polysulfides formed in the dissolution of sulfur in ammonium sulfide. The rate of formation of thiocyanide exceeds the rate of oxidation of sulfide by the catalyst in the oxidized form, the difference increasing with temperature. The higher rate of formation of thiocyanide makes this reaction selective in the process of oxidative purification 4.Platinum Catalyst for Purification of Coke Oven Gas from Acetylene. (Platinum Catalyst for Purification of Coke Oven Gas from Acetylene.) Klimiec, Jacek; Atamanczuk, Bronislaw; Nowicki, Boguslaw Source: Przemysl Chemiczny, v 59, n 6, p 334-336, Jun 1980 Language: Polish Abstract: In the reported experiments, the usability of platinum catalysts on metal base in the process of hydrogenation of acetylene contained in coke oven gas has been investigated. It is found that platinum catalyst on the carrier, modified with boric acid and thorium nitrate, is capable of removing 100% of acetylene, at the temp. 550 K and the catalyst loading with 3 divided by 7 Nm**3/kg//c//a//t//. multiplied by (times) hr of gas, without changing the ethylene content 5.PRODUCTION OF AMMONIUM THIOCYANATE DURING OXIDATIVE PURIFICATION OF COKE-OVEN GAS. Lebedeva, G.N.; Panferova, G.D.; Kuznetsova, Z.I. Source: Coke and chemistry U.S.S.R., n 3, p 44-47, 1980 Abstract: Investigations were conducted on the separation of ammonium thiocyanate from the liquors of oxidative sulfur and cyanide removal from coke-oven gas, used in plants in the East. On artificial mixtures it was shown to be possible to separate ammonium thiocyanate from liquors containing ammonium thiosulfate and sulfate. The quantitative limits of these impurities were determined. Ammonium thiocyanate meeting the specifications of GOST standard 19522-74 with a yield of 89% was obtained from oxidative purification liquors with a catalyst by means of hydroquinone 6.TESTING OF A PROCESS OF OXIDATIVE REMOVAL OF SULFUR AND CYANIDE FROM COKE OVEN GAS. Andrzheevskii, M.Yu.; Lyapkin, A.A. Source: Coke and chemistry U.S.S.R., n 9, p 63-67, 1987 Abstract: The process of oxidative sulfur and cyanide removal using CDSP (Cobalt Disulfophthalocyanin) catalyst ceases with accumulation of free cyanide ion in the wash solution. Practical use of this process requires constant bonding of cyanide by a stoichiometric quantity of sulfur. A thermal retention of the solution should be provided to accelerate thiocyanate formation. 7. Development of the coke gas desulfurization technology Platonov, Oleg I.1 Source: 2006 TMS Fall Extraction and Processing Division: Sohn International Symposium, v 5, p 193-201, 2006, Sohn International Symposium: Advanced Processing of Metals and Materials - Proceedings of the International Symposium Abstract: The process for desulfurizing coke oven gas in a regenerative system "scrubber-stripper", with sour gas being fed to Sulfur Recovery Unit (SRU) and tail gas being recycled to raw coke gas scrubber, has been developed. A key problem of this process is the presence of elemental sulfur in the SRU off-gas, which may deposit on gas-blowing equipment, thus disrupting its operation. A new treatment technology for SRU off-gas that has been worked out for a Claus unit operated by « Russian Metallurgical Company » (RMC) in Magnitogorsk (Russia) is presented. It incorporates a catalytic hydrolysis/hydrogenation stage, where all sulfur-bearing species such as sulfur dioxide, carbonyl sulfide and elemental sulfur are converted to hydrogen sulfide. The SRU in Magnitogorsk comprises three main units: gas re-heater; catalytic hydrolysis reactor and waste gas cooler. Re-heater is required to increase temperature of the process gas up to a level of catalytic conversion (beyond 330-3500C). Oxygen utilized as an oxidizing agent reduces the volume of waste gas to a minimal possible value. The operational data garnered since 16.07.2004 clearly shows that the new technology allows high-level purification of Claus tail gas from elemental sulfur. Unlike SCOT - process, this technology does not require separate stages for H2S removal and enrichment that tangibly simplifies its implementation at lower capital and operation expenditures 8.Desulfurization of Biogases on Gas Purification Material. (Desulfurization of Biogases on Gas Purification Material.) Drautzburg, Guenter1 Source: GWF, Gas - Erdgas, v 126, n 1, p 36-41, Jan 1985 Language: German Abstract: Dry biogas desulfurization is practiced most often in sewage treatment plants. Most of the time, tower desulfurizers containing a coarse-grained, abrasion-resistant purification material (ferric hydroxide) are employed for this purpose. Up to the point where total saturation with sulfur is achieved, this material is either charged and regenerated by air alternately, or else air is added to the untreated gas, so that both reactions can occur simultaneously. Tower desulfurizers are designed for long periods of operation. At large sewage treatment plants hurdle purifiers such as those used for the purification of coke oven gas are also employed. 9.Refinery process for processing coke oven gas, involves selectively removing ammonia and hydrogen sulfide after converting unsaturated hydrocarbons to obtain ammonia and hydrogen sulfide 专利号: JP2000248286-A 摘要: NOVELTY - Unsaturated hydrocarbons are converted into saturated hydrocarbons and H2O, HCN, NH3 and CO are converted into CH4 and/or NH3 while COS is converted into H2S. The removal of one of NH3 and H2S whose existence causes problems is selected. The removal of the other is then selected. USE - For processing coke oven gas obtained as a byproduct during dry distillation of coal to manufacture coke. ADVANTAGE - The purification of the COG can be performed reliably, since impurities which cause problems in a next step are removed during the previous step, while selectively removing NH3 and H2S. Good operativity and good economical efficiency can be secured, while refining the COG into a heating gas or a raw material gas for chemical industries, since removal of impurities can be smoothly performed in each step. Contamination to the environment can be prevented. 详细说明 - At least the heavy parts, e.g. tar and dust, are removed, when performing refinery processing of a coke oven gas (COG) containing impurities such as hydrogen sulfide (H2S), carbonyl sulfide (COS), ammonia (NH3), hydrogen cyanide (HCN) and the unsaturated hydrocarbons which contain 2-4C in a molecule and oxygen. The conversion of unsaturated hydrocarbons is performed into saturated hydrocarbons containing 2-4C by hydrogenation and making the hydrogen combine with oxygen to form water. The hydrolysis and/or hydrogenation of the HCN and NH3 is performed in the presence of hydrogen contained in the water vapor while converting the carbon monoxide (CO) and ammonia (NH3) into methane (CH4). 10.Coke oven gas purificn. - by hydrogenating unsatd. hydrocarbon cpds. and oxygen in the core oven gas with palladium catalyst 专利号: JP61089294-A; JP91049960-B 摘要: Process comprises hydrogenating unsatd. hydrocarbons and oxygen on the coke oven gas with Pd catalyst. Pd catalyst is one contg. almost no chlorine. The temp. of the coke oven gas at the inlet of the Pd catalyst is held 100-200 deg. C. The temp. of the gas at the outlet of the Pd catalyst zone is 270-330 deg. C by the exothermic deoxidation of O-cpds. and hydrogenation of unsatd. hydrocarbons. No external cooling device is necessary for the reactor. The gas is then treated with hydrodesulphurisation catalyst (e.g. Ni, Ni-Mo catalyst etc.) for removing organic S-cpds., or with zeolite, etc. to separate hydrogen. USE/ADVANTAGE-As aromatic cpds. or oxides of nitrogen are removed previously by compressing the coke oven gas to 60-150 deg. C in a hot bottle to cause polymerisation of acetylenes or dienes and absorbing such components with oil, no NOx nor aromatic cpds. are contained in the feed gas. The gas is then treated with Pd catalyst to hydrogenate oxygen or unsatd. hydrocarbons selectively and sufficiently. Addn. reaction of H2S, if any, to remaining unsatd. hydrocarbon, resulting by-prodn. of organic S cpds. nor organic acids, are avoided. Corrosion of the reactor is prevented. 11.Fuel gas purification - by two=stage catalytic hydrogenation at two different temps. 专利号: JP59230090-A 摘要: Process for purifying coke oven gas contg. dienes, O2, olefins and S cpds. comprises hydrogenating the gas in two stages wherein dienes and O2 are predominantly contact hydrogenated at the inlet temp. of 100-230 deg.C and hydrogenating temp. or up to 350 deg.C in the presence of catalyst comprising Ni and/or Co or metal of Pt gp. in the first stage and the remaining olefins and S cpds. are contact hydrogenated at the outlet temp. of up to 450 deg.C in the presence of catalyst comprising Ni and/or Co and M Mo in the second stage. The first stage is carried out by recycling a portion of purified gas in an amount of 10-1,000 % of the crude coke oven gas at 150 -350 deg.C, press of 2-100 kg/cm2 and SV of 500-50,000 hr-1. The second stage is carried out at 300-450 deg.C and SV of 500-50,000 hr-1. After the second stage formed H2S may be removed by using solid absorbent (e.g. ZnO, Fe2O3, CuO or activated carbon. ADVANTAGE-The two stage process reduces polymerisation of dienes to form gummy material since the first stage hydrogenation is at a relatively lower temp. 12.Hydrogenation of hydrocarbon oils 专利号: JP71016672-B 专利权人和代码:NIPPON STEEL CHEM CO(YAWH-C) 摘要: Method of purifying hydrocarbon oils contng. aromatic hydrocarbons (e.g. coke oven light oil,oil gas light oil or cracked gasoline) by two-step method comprises contacting the hydrocarbon oils with a nickel-molybdenum catalyst of 0.5-3 atomic ratio of nickel to molybdenum in liquid phase or gas-light mixed phase, in the presence of hydrogen as 0.5-10 mol. per 1 mol. of hydrocarbons, at 100-170 degrees C., 10-60 kg./cm.2 hydrogen partial pressure, and 1-10 hr.-1 LSV. The resulting primary hydrogenation reaction mixture is contacted with secondary hydrogenation purification catalysts in vapour phase in presence of hydrogen (0.5-10 mol. per 1 mol. of hydrocarbons) at 250-500 degrees C., 10-50 kg./cm.2 hydrogen partial pressure, and 0.4-5 hr. -1 LSV. The purified oils do not contain sulphur compounds, nitrogen compounds, oxygen compounds, and ethylenic unsatd. compounds. 13.Catalytic hydrogenation of polycyclic aromatic hydrocarbons with coke oven gas BRAEKMAN-DANHEUX C; FONTANA A; LAURENT P; LOLIVIER P Fuel : (Guildford) , 1996 , Volume: 75 , Number: 5 , Page: 579-584 Abstract: To improve the economy of the conversion of polyaromatic molecules to their hydroaromatic analogues, catalytic hydrogenation of phenanthrene has been carried out under pressure of different simulated coke oven gases instead of pure hydrogen. The influence of reaction time, temperature and pressure on the hydrogenation yields and on the nature of the obtained products has been studied. Comparisons have been made with reaction with pure hydrogen under the same conditions. The influence of the different components of a real coke oven gas has also been indicated. The results indicate that coke oven gas can be used if the goal is to obtain not perhydroaromatic compounds for thermal cracking but partly hydrogenated compounds to be used as hydrogen donor solvent in a coal liquefaction process. The results have been applied to highly aromatic fractions of coal tar. 查看更多9个回答 . 4人已关注
