Abstract
A hydrocarbon feed for use in a catalytic conversion process that utilizes a zeolite catalyst, and that contains a catalytically deleterious impurity, is refined by contact with a zeolitic sorbent. The invention is applicable to dewaxing, with an example illustrating reduction by 100.degree. F. of the initial equilibrium (lineout) temperature by the method of this invention. Other reactions include conversions of aromatic hydrocarbons such as alkylation, isomerization and disproportionation.
