The influence of copper dilution on HZSM-5 catalytic performance in the conversion of methanol to gasoline

摘要

As a diluent, nano-copper was mixed with HZSM-5 for gasoline production from methanol. Diluents have positive effect on the catalyst stability, for diluents help to enhance heat emission. C2-C3 alkenes and DME contents increased obviously while C_3H_8 content decreased with the addition of copper. COx and H_2 were also observed for the methanol reforming on Cu species. The content of different compositions in the oil products were almost the same as that on HZSM-5 catalyst without diluents.
