A process wherein a residuum feedstock is upgraded in a short vapor contact time thermal process unit comprised of a horizontal moving bed of fluidized hot particles, then fed to a fluid catalytic cracking process unit. Hot flue gases from the fluid catalytic cracking unit is used to circulate solid particles and to provide process heat to the thermal process unit.

Integrated residua upgrading and fluid catalytic cracking

A process for deasphalting a residua feedstock by use of a short vapor contact time thermal process unit comprised of a horizontal moving bed of fluidized hot particles. It is preferred that a mechanical means be used to fluidize a bed of hot particles.

Process for deasphalting residua (HEN9511)

An improved fluidized bed coking process wherein a residuum feedstock is introduced into a first stage comprised of a short vapor contact time reactor containing a horizontal moving bed of fluidized hot particles. Carbonaceous material is deposited onto the hot particles on contact with the hot particles, and a vapor product is produced. The hot particles, containing the carbonaceous deposits, are fed to a second stage fluidized bed coking process.

Fluidized bed coking process

A hydroconversion process for converting a heavy hydrocarbonaceous feedstock to lower boiling products, which process involves the use of a sulfided catalyst concentrate which is prepared in a continuous plug-flow mode. The heavy hydrocarbonaceous feedstock is reacted with said catalyst concentrate in the presence of hydrogen at hydroconversion conditions.
