Ｚｅｏｌｙｓｔ和ＳＫ公司合作开发成功两种由重整油生产苯、甲苯、二甲苯 (ＢＴＸ)的新型催化剂。两种催化剂均为贵金属 沸石型组合催化剂 ,重整油中的芳烃化合物通过先进改质工艺 (ＡＲＴ) ,在贵金属催化剂作用下 ,发生加氢脱烷基和烷基转移反应制得混苯 (ＢＴＸ) ,而非芳烃
Zeolyst and SK have successfully developed two new catalysts for the production of benzene, toluene and xylene (BTX) from reformate. Both catalysts are precious metal zeolite composite catalysts. The aromatic compounds in the reformate undergo the hydrodealkylation and transalkylation reactions under the action of precious metal catalysts through the advanced modification process (ART) ) Rather than aromatic
