主 题:Butene utilization Bifunctional catalysts OXZEO Syngas conversion Gasoline
摘 要:With the expansion of butene production capacity,clean and efficient conversion of mixed butene attracts increasing *** we report direct co-conversion of butene and syngas to highquality gasoline enabled by a bifunctional OXZEO catalyst comprising ZnCrO_(x) oxide and ZSM-5 zeolite.A gasoline selectivity of 71.6% at 98.1% butene conversion and 26.2% CO conversion have been obtained under the reaction conditions of 360℃,3 MPa and 3000 mL g^(-1) h^(-1).The space time yield of gasoline of0.25 g·g^(-1) h^(-1) is ***,the presence of syngas can effectively facilitate iso-paraffin production while hindering the formation of *** is attributed to the prohibited hydrogen transfer aromatization process of butene on ZSM-5 in the presence of *** rthermore,the formation of isomers of gasoline range hydrocarbons is favored because the active intermediates generated from CO/H_(2) activation over ZnCrO_(x) oxide could react with butene over ZSM-5 ***,the product distribution among gasoline range hydrocarbons is modulated with reduced heavy aromatics and improved iso-paraffins,which is desirable for application as *** provides an alternative environmentally friendly technology to utilize still increasing mixed butene.
