Pretreatment of catalytic conversion feedstocks.

摘要

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 permitting the reduction by 38°C (100°F) of the initial equilibrium (lineout) temperature and other reactions which include conversion of aromatic hydrocarbons such as alkylation, isomerization and disproportionation.
