SDC-9000是一种新型的以五元环族分子筛为主要活性组元的催化剂。该催化剂可采用重质石油烃为原料，在560℃~650℃的反应温度下，生产乙烯和丙烯为主的低碳烯，并且改变反应条件可调节乙烯/丙烯产率的比例，满足市场对乙烯和丙烯产率变化的要求。
It is new catalyst, which adopting ZSM-5 type zeolite as the main active component. SDC-9000 is characterized by maximizing ethylene and propylene simultaneously at a reaction temperature of560℃~650℃ with heavy petroleum hydrocarbon as feedstock, moreover, the radio of ethylene/propylene yields can be adjusted by controlling process parameters to meet the demands for ethylene and propylene in the market.
