摘要
Abstract
A series of co‐pyrolysis tests of naphtha and methyl cyclohexane were carried out to study the products yield changes in pyrolysis of different proportions and at different tempera‐tures .The result showed that comparing with the naphtha pyrolysis alone ,the yield of co‐pyrol‐ysis ethylene decreased w hile the yield of butadiene substantially increased .Relatively high tem‐peratures are benefit for high butadiene yield while smaller drop of ethylene yield .The co‐pyroly‐sis of naphtha and methyl cyclohexane can optimize the pyrolysis gas product distribution and im‐prove the comprehensive added value of products .It can fully rely on existing ethylene pyrolysis unit and subsequent separation system .Meanwhile ,co‐pyrolysis has the advantages of high feasi‐bility ,lower investment and stable operation ,which can meet the requirements of industrial pro‐duction .关键词
