Figure Abstract

Caption

The bifunctional catalysts consisting of spinel ZnAlOx and SAPO-11 zeolite can directly convert syngas (a mixture of H2 and CO) into high-quality gasoline. The selectivity of C5−C11 gasoline-range hydrocarbons can reach 79% with a high content of iso-paraffins. The formation of iso-paraffins over ZnAlOx/SAPO-11 catalyst follows a pore-mouth catalysis mechanism, which means the isomerization of linear hydrocarbons can only take place near the pore mouth region of zeolite channels.
