Abstract
A catalytic reaction process which involves exposing a hydrocarbon feed including nitrogenous contaminants as well as dialkyl sulfides to a material capable of adsorbing the nitrogenous contaminants as well as dialkyl sulfides from the feed before introducing the stream substantially devoid of nitrogenous contaminants and dimethyl sulfide into a feed zone of a reactor; contacting the hydrocarbon stream with a catalyst material in the reaction zone; and catalytically reacting the hydrocarbon stream under conditions which favor forming a reaction product and inhibiting reaction of nitrogenous contaminants and dimethyl sulfide with the catalyst material.
