The catalyst BC-1-037 provided by Beijing Research Institute of Chemical Industry for the selective hydrogenation of C_2 fractions in gas phase was employed in the 300000t/y ethylene plant of Shanghai Petrochemical Complex. Thecatalyst was put in one of the single bed hydrogehators and operated under the technical condition similar to those for imported catalyst. Within 15 minuts after operation, the acetylene content was reduced to less than 1 ppm in the reactor effluent.The activity, selectivity and stability of the catalyst are good. Now it has been running for more than 4000 hours and is still running.

北京化工研究院提供的国产碳二气相选择加氢催化剂(BC-1-037),装填于上海石化总厂乙烯厂的一台碳二加氢反应器中,第一次在30万吨/年规模乙烯装置上工业应用,替代进口催化剂,一次投用成功。国产催化剂活性高,选择性好,稳定性优良,投入乙烯生产流程使用,只经过15分钟的工艺操作条件调整,达到平稳运转,脱除乙炔至小于1ppm,在不停车切换催化剂的情况下,仍生产出合格的乙烯产品。已累计运转4000小时,并继续在使用中。试验结果表明,国产碳二加氢催化剂适用于引进乙烯装置,满足工业生产的要求,可替代进口催化剂使用。

This article introduces the application of homemade catalyst BC-H-20B for selective acetylene hydrogenation in Yanhua ethylene plant.The experiment results show that the homemade catalyst BC-H-20B has good activityselectivitystability and resistant fluctuation capability.Compared with imported catalyst,it can be proved that the homemade catalyst BC-H-20B has better quality than imported one. The homemade catalyst BC-H-20B can be used widely and substitutes the import in domestic ethylene plants.
