生焦量的计算？ 为了用空气用量来计算焦炭的含量，可以使用以下公式来计算： x（wt%）=100/[1+ccr /（0.488*（0.21-y）*at ）] 式中： x ＝待生催化剂焦炭含量，%（重量） ccr ＝催化剂循环量，kg/hr（磅/小时） ccr=设计最大催化剂循环量*实际催化剂循环速率百分比 y ＝烧焦区入口氧气浓度，摩尔分数 at ＝总燃烧空气用量，nm3/hr（标准立方英尺/小时） 注释：对于白色催化剂燃烧条件（仅仅注入下部空气），使用 at ＝ al － vl 式中： al ＝去干燥区的空气流量，nm3/hr（标准立方英尺/小时） vl ＝过剩空气放空量，nm3/hr（标准立方英尺/小时） 对于黑色催化剂燃烧条件（仅仅注入上部空气），使用 at ＝ au 式中： au ＝去烧焦区的空气流量，nm3/hr（标准立方英尺/小时） 这个公式可以采用图表形式以方便使用。 方法计算出的催化剂焦炭含量，只是表示当前进入再生器烧焦的催化剂的焦炭含量。 并没有预测重整反应中的催化剂积碳速率的功能。只能提供给操作人员观察一定时期内催化剂焦碳含量的变化趋势，以及催化剂积碳是否超过预期值，是否需要下调重整反应的苛刻度。 对于楼上所说的，这样算出的催化剂碳含量不准确，我表示不能苟同。反而我认为使用这个方法计算出得催化剂碳含量很准确，完全可以和生产实际对应。催化剂的采样、分析都有偶然性，相比连续性的耗氧量的推算碳含量更有局限性。查看更多
