Abstract:
A process for reforming hydrocarbons, the process comprising the steps of:a) passing a feedstock comprising hydrocarbons to a first catalyst bed containing catalyst particles wherein the feedstock enters the first catalyst bed at a first inlet temperature, contacting hydrocarbons with catalyst particles and reforming hydrocarbons in the first catalyst bed, and withdrawing from the first catalyst bed at a first outlet temperature a first bed effluent stream comprising hydrocarbons, wherein the first outlet temperature is less than the first inlet temperature;b) passing at least a portion of the first bed effluent stream to a second catalyst bed containing catalyst particles wherein the at least a portion of the first bed effluent stream enters the second catalyst bed at a second inlet temperature that is at least about 100.degree. F. greater than the first inlet temperature, contacting hydrocarbons with catalyst particles and reforming hydrocarbons in the second catalyst bed, and withdrawing from the second catalyst bed a second bed effluent stream comprising reformate;c) recovering reformate from the second bed effluent stream; andd) at least periodically moving catalyst particles through the first catalyst bed and the second catalyst bed by withdrawing catalyst particles from the second catalyst bed, passing catalyst particles from the first catalyst bed to the second catalyst bed, and adding catalyst particles to the first catalyst bed.
