Abstract
In a process for reforming light naphtha with a bimetallic or multimetallic reforming catalyst, such as a platinum-rhenium-halogen catalyst, at conventional reforming conditions, wherein the catalyst is used for an extended continuous on-stream period, the aromatics selectivity of the catalyst is rapidly increased by contacting the naphtha and hydrogen with the catalyst at increased severity operating conditions, such as a reduced pressure less than 90% of the normal reforming pressure, during an initial portion of the on-stream period.
