摘要
介绍了从催化裂化干气中分离氢,干气作制氢原料,干气与苯烷基化反应制乙苯和干气浓缩后送乙烯装置回收乙烯和轻烃等干气的回收利用途径,其中以后一种方法为佳。
FCC dry gas was an important chemical raw material.The separation of hydrogen and the preparation of hydrogen from FCC dry gas,the preparation of ethylbenzene by the alkylation of benzene and FCC dry gas,and the recovery of ethylene and light hydrocarbon by concentrating FCC dry gas were introduced.It was pointed out that the last method was more feasible in economy.
