Hydrocarbon conversion with additive loss prevention

U.S. Patent Number: 5336834

Abstract: An adsorption arrangement in combination with a catalytic hydrocarbon conversion process suspends non-hydrocarbon materials that act to enhance the operation of the conversion zone by using an adsorption zone arrangement to keep the compounds in recirculation about the reaction zone. The process of this invention is particularly useful for the isomerization of hydrocarbons wherein the adsorption zone arrangement operates to maintain chloride compounds in the reaction zone and to prevent contamination of product streams with the chloride compounds. This invention can be used in combination with traditional adsorptive methods of removing contaminant from feedstreams that enter reaction zones. The invention is also useful for sulfided catalysts where it is desirable to maintain sulfur within the reaction zone and keep sulfur contamination from entering product streams.
