Claim Text:
1. A process for catalytically hydroisomerizing FT (Fischer-Tropsch) C 20-105 paraffins, comprising contacting the FT C 20-105 paraffins with a catalyst, at a temperature ranging from 200° C. to 270° C., wherein the FT paraffins are in a liquid phase, and at a pressure ranging from 2 to 20 MPa, in the presence of hydrogen, to produce a microcrystalline paraffin; wherein the catalyst comprises 60 to 95% by mass of zeolite of the beta type, based on the combination of all components fired at 800° C., 5 to 39.8% by mass of gamma-aluminum oxide having a specific surface area of 150-350 m 2 /g, calculated as Al 2 O 3 and based on the combination of all components fired at 800° C., and one or more metals of transition group 8 of the periodic table, in an amount of 0.1 to 2.0% by mass, based on the combination of all components fired at 800° C., the one or more transition group 8 metals being attached to the gamma-aluminum oxide; and wherein the catalyst is prepared by a process comprising the steps of:
