HYDROCARBON CONVERSION OF SULFUR CONTAMINATED FEED STOCK ABSTRACT A process for the alkylation of aromatic hydrocarbons in a reaction zone containing a crystalline silica polymorph silicalite catalyst. The feed stock to the reaction zone comprises an alkylating agent and an aromatic substrate contains sulfur in an amount, greater than 2 ppm, which heretofore has considered to be unacceptable to zeolite catalysts. A steam cofeed may also be applied to the reaction zone in an amount sufficient to reduce the deposition of coke on the catalyst due to the presence of sulfur. Sulfur may be present as a contaminant in the aromatic substrate or the alkylating agent.
