德国EDL公司有相关的煤制油技术？ edl工艺的全称为： high-pressure catalytic hydrogenation of coal，应该是煤直接液化技术。 公司1960年代就开始煤高压催化加氢的技术研究，相关中试装置从1984年到1991一直运行着，积累了大量工程数据。1986-1989年曾设计过95 t/d 和 350 t/d两套工业化装置。 edl的工艺包括以下内容: • coal preparation and slurrying • reaction system with liquid-phase hydrogenation and recycle gas system • vacuum flash distillation • atmospheric distillation 当然还包括一些公用工程方面系统支持，如emergency expansion system; hydrogen production, steam and condensate system, process water system etc. 原料要求：煤： ash content ~ 15 wt% (related to dry substance) sand content ~ 1 wt% (related to dry substance) salt content ~ 2 wt% in the ash 氢气： h2 ~ 92 vol% co ~ 10 ppmv co2 ~ 0.1 vol% 主要工艺指标如下： • 产率 approx. 50 - 60 % light/middle oil mixture and cracked gas without vacuum residue and resp. approx. 85 % light/middle oil mixture and cracked gas with vacuum residue • 催化剂用量：进料煤的1.5-2% • h2：约900-1100nm3/tcoal • 气体/产品比：约1300-1500nm3/m3slurry 基于以上经验特别是在褐煤的加氢领域，我们可提供以下服务： • analysis of coal quality and evaluation of the hydrogenation ability of coal • pre-investigation as to the selection of specific equipment • balancing of the main process • technical evaluation of process options • planning of small-scale, continuously working pilot plants to execute basic investigations • preparation of feasibility studies • investigations of the site • basic engineering for large-scale pilot plants to determine backed planning fundamentals for production plants • design of process stages for large-scale pilot plants with a capacity of approx. 25 kt/y coal (daf) under consideration of the main equipment requirements and local conditions • general planning of production plants 这回应该够详细了！查看更多
