US Patent:

47131675, Dec 15, 1987

Filed:

Jun 20, 1986

Appl. No.:

6/876640

Inventors:

Mark E. Reno - Villa Park IL
Robert K. Olson - Elgin IL
Tom N. Kalnes - La Grange IL

Assignee:

UOP Inc. - Des Plaines IL

International Classification:

C10G 6510

US Classification:

208 59

Abstract:

A multiple single-stage process for the conversion of heavy hydrocarbonaceous charge stock into a lower boiling distillate hydrocarbon product. Fresh charge stock and hydrogen are introduced into a first catalytic reaction zone for substantially 100% conversion of the feed. Hydrocracked product effluent from the first hydrocracking reaction zone which comprises a predetermined distillate fraction is passed with an accucracked effluent from a second catalytic hydrocracking or accucracking reaction zone into a separation zone and separated into various hydrocarbon streams including a light hydrocarbon stream comprising the distillate product, a middle hydrocarbon stream and a heavy hydrocarbon stream. The middle hydrocarbon stream comprising said distillate fraction and hydrogen is introduced into the second catalytic hydrocracking or accucracking reaction zone for conversion into a lower boiling accucracked effluent stream comprising the distillate hydrocarbons boiling in the distillate product range. The accucracked effluent is admixed with the hydrocracked effluent as described above.

US Classification:

252415

Abstract:

A continuous method for regenerating deactivated catalyst particles in a regeneration zone through which the particles are downwardly movable by way of gravity-flow. Particles are initially introduced into an upper carbon-burning/halogenation zone wherein they are contacted, in a first section, with a first air stream and a first mixture of steam and a halogen, or halogen-containing compound. Partially regenerated/reconditioned particles are then contacted, in a lower second section, with a second air stream and second mixture of steam and halogen. From this two-sectioned, carbon-burning/halogenation zone, the catalyst particles flow via gravity into a drying zone wherein they are contacted by a substantially dry air stream.
