催化干气制乙苯技术是由抚顺石化公司石油二厂、中科院大连化物所、洛阳石化工程公司、石油三厂联合开发的一项新技术。该技术将催化裂化过程中的干气直接引入苯烷基化反应器。在一定温度、压力、空速、苯烯比的条件下,干气与苯、反烃化料直接接触。干气中的乙烯、反烃化料分别与苯发生烃化反应和反烃化反应。反应产物中除了含有大部分气体 Catalytic dry gas production of ethylbenzene technology by the Fushun Petrochemical Company Second Plant, Institute of Chemical Physics, Dalian Institute of Chemical Engineering, Luoyang Petrochemical Engineering Company, the three oil plant jointly developed a new technology. This technology introduces the dry gas from the catalytic cracking process directly into the benzene alkylation reactor. Under a certain temperature, pressure, space velocity, benzene to benzene ratio conditions, dry gas and benzene, anti-hydrocarbon material in direct contact. Ethylene and anti-hydrocarbon materials in dry gas are respectively alkylated with benzene and reacted with hydrocarbon. The reaction product contains most of the gas
