摘要
比较了延迟焦化与催化裂化的经济性 ,在目前的价格情况下催化裂化的效益略高于延迟焦化。通过对延迟焦化汽油加氢后与普通直馏汽油的乙烯裂解试验和比较 ,延迟焦化汽油加氢后可以作乙烯原料。循环比的变化对产品分布影响很大 ,但循环比变化对经济效益影响不大。
A comparison of economic indicators between delayed coking and catalytic cracking indicates that,under the condition of current price,the economic benefit of the latter is slightly higher than that of the former.Through the test and comparison of ethylene cracking of hydrogenated delayed coking gasoline and regular grade straight-run gasoline,it is showed that the former can be used as ethylene stock.The change of recycle ratio has quite big influences on the product distribution,but not very big on the economic benefit
