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.
