Abstract: Disclosed is a process for converting heavy hydrocarbonaceous feedstock to more valuable products. The feedstock is introduced into a coking unit containing a coking zone and a scrubbing zone. The bottoms fraction from the scrubbing zone is passed through a microfiltration unit, thus removing fine coke particles which are recycled to the coking zone. The substantially solids-free filtrate is hydrotreated, then passed to a catalytic cracking unit.

Abstract: 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 C.sub.4.sup.-- hydrocarbon gases are separated between stages. A portion of the hydrogen-rich gaseous stream is recycled and the remaining portion along with the C.sub.5.sup.+ stream are sent to second stage reforming.

Abstract: A two stage catalytic reforming process. The first stage is comprised of two separate fixed-bed reforming units each comprised of one or more serially connected fixed-bed reforming zones. The second stage is comprised of one or more moving-bed reforming zones with continual catalyst regeneration. A hydrogen-rich gaseous stream is separated after each fixed-bed unit and a portion is recycled to the respective fixed-bed reforming zones.
