Therefore, the Pt catalyst supported on the SAPO-11 synthesized in the biphase medium exhibited much higher catalytic activity for the hydroisomerization of n-dodecane than that supported on the SAPO-11 synthesized in an aqueous medium.

Based on the reported reaction networks, a novel six components hydroisomerization reaction network with a new lumped species including C8-naphthenes and C8-paraffins was proposed and a kinetic model for commercial unit was also developed.

The action of the paraffin hydroisomerization technology were summarized in the paper,the paper introduced the characteristic of the three kind catalyst and five kind processing flow used by the technology as well as the patent technology of the UOP company,analyzed how to select the technic.

The Improvement of Pt/SAPO-11 Hydroisomerization Catalysts;

It was shown that reaction temperature has the greatest impact on the hydroisomerization of n-tetr.

The present problems for Ca utilization are separation of single component and removal of residual butadiene in C_4 streams,n-Butene hydroisomerization technology takes advantages of reaction reversibility,low temperature,selective hydrogenation of butadiene and easily to combine with catalytic distillation,which is the spot of recent interest.

Their catalytic activities were evaluated in the hydroisomerization of n-heptane with an atmospheric fixed-bed reactor.

Their catalytic behaviors were measured in the hydroisomerization of n-heptane in an atmospheric fixed-bed microreactor.

The Pt/WGZ catalyst gave a constant n-heptane hydroisomerization activity for over 80 h with a high n-C7 conversion(76%) and C7 isomer selectivity(94%).
