CATALYTIC ISOMERISATION OF WAX WITH A HIGH POROSITY, HIGH SURFACE AREA ISOMERIZATION CATALYST

摘要

new catalyst with high surface area, porosity, and used in the process of isomerization of wax, mainly for the production of base oils or oils mixed with high viscosity index and low pour point.the catalyst contains a metal selected from the group consisting of the catalytic properties of group vib metal and a group viii, and mixtures thereof, preferably of the noble metals of group viii, and their mixtures, or platinum, which is present in amount of metal is between about 0.01 and 5.0% by weight; and the metal includes a fluorine from between about 0.01 and 10% by weight. the catalyst comprises a refractory metal oxide support preferably in the majority (i.e. at least 50% by weight of alumina or alumina consisting entirely of, for example, alumina, gamma and eta.the catalyst is a porous end in pore volume, at least about 50 cc / g and a surface area such that when multiplied by the surface area and porosity is at least about 10, preferably at least about 110, or at least approximately 115. or better yet, at least approximately 120.this process makes it possible to transform a high performance, liquid wax isomerization products, preferably lubricating oil base or mixed with high viscosity index and low pour point.
