Fixed-bed/moving-bed two stage catalytic reforming

摘要

A two stage process for catalytically reforming a gasoline boiling range hydrocarbonaceous feedstock. The reforming is conducted in two stages wherein the first stage is operated in a fixed-bed mode, and the second stage is operated in a moving-bed continual catalyst regeneration mode. A gaseous stream comprised of hydrogen and predominantly C4- hydrocarbon gases are separated between stages. A portion of the hydrogen-rich gaseous stream is recycled and the remaining portion along with the C5+ stream are sent to second stage reforming.
