摘要: Abstract Hybrid catalysts prepared by contacting zinc or gallium oxide containing particles with the ZSM-5 zeolite crystallites coating these latter species, exhibit aromatizing activity which is comparable to that of using conventional impregnation technique. Involvement hydrogen back spillover mechanism has been suggested.
