碳三馏份液相选择加氢催化剂的工业应用

Industrial Application of Catalyst for Liquid Phase Selective Hydrogenation of C_3 Fractions

辽阳化纤公司化工一厂引进的7.3万吨/年乙烯装置,双段床碳三液相加氢除丙炔丙二烯,使用进口催化剂,北京化工研究院研制的碳三液相加氢催化剂(C_3-L-80),装填于其中的一台工业反应器替代进口催化剂试用,按引进装置的碳三液相加氢工艺操作,无论作第一段反应床或作第二段反应床,反应性能均达到进口催化剂的水平;加氢结果合格,达指标要求;稳定性好,适用于引进乙烯装置的碳三液相加氢工序,脱除碳三馏份中的丙炔至小于5ppm、丙二烯小于10ppm。研制的催化剂在该装置上运转长达5年。

Catalyst C_3-L-80,the selective hydrogenating catalyst of C_3 fractions inliquid phase,provided by Beijing Research Institute of Chemical Industry,wasemployed in the ethylene plant imported by Liaoyang Petrochemical Fiber Cor-poration,The catalyst was put in one of the hydrogenators and operated under thesame technical conditions of the imported plant.Its activity,selectivity and sta-bility was up to the standards of the imported catalyst in either first-bed or se-cond-bed hydrogenators.When the double-bed hydrogenator was used,the methylacetylene was less than 5ppm and propadiene less than 10 ppm in the effluent.The catalyst has been used in the commercial installation for five years.
