Abstract
A catalyst useful for hydroisomerizing wax containing feeds comprises a Group VIII metal on an alumina or silica-alumina support having less than about 35 wt % silica and is surface treated with at least about 0.5 wt % silica or a silica precursor.
Claims5
A process for isomerizing was in a wax containing feed by contacting a wax containing feed and hydrogen, at isomerization conditions, in the presence of a catalyst, the improvement comprising using a catalyst having a surface area of about 180-400 square meters per gram and comprising a Group VIII metal and at least 0.5 wt % silica deposited on the surface of a support consisting of alumina or silica alumina wherein the silica content of the support is less than about 35 wt %.
