ABSTRACT:
Provided is a process for catalytically reforming a hydrocarbon feedstock using a highly sulfur sensitive catalyst. The process comprises contacting the hydrocarbon in a reaction zone, with the hydrocarbon feed and catalyst flowing in opposite directions. Once the catalyst has passed through the reaction zone, it is then passed to a regeneration zone for regeneration. The process eliminates the need of passing the hydrocarbon feed through a sulfur sorber prior to entry into the reaction zone, as the spent catalyst which is leaving the reaction zone for regeneration acts as a sulfur sorber and removes the sulfur from the feed entering the reaction zone.
