Abstract: A process is provided for dehydrogenating a paraffinic hydrocarbon comprising sending the paraffinic hydrocarbon to a fluidized bed reactor to be contacted at dehydrogenation reaction conditions with a catalyst composition comprising less than about 0.0999 wt % platinum and about 0.05-2.5 wt % Group I or Group II elements or a mixture thereof. The catalytic composition is prepared without addition of tin, gallium, indium, germanium or lead.

IPC: C07C4/06

CPC classification number: C07C4/06

Abstract: The process converts ethylene in a dilute ethylene (dry gas) stream that may be derived from an FCC product to propylene. The process includes an oligomerization step to convert ethylene in the dilute ethylene stream to heavier olefins, and a second reaction step to convert the heavier olefins to propylene. The oligomerization catalyst may be an amorphous silica-alumina base with a Group VIII and/or VIB metal. The catalyst is resistant to feed impurities such as hydrogen sulfide, carbon oxides, hydrogen and ammonia. At least 50 wt-% of the ethylene in the dilute ethylene stream can be converted to C4+ olefins and recycled to the FCC for cracking to propylene.

Abstract: A process for catalytic production of olefins comprises contacting a first hydrocarbon stream and a first stream of fluid catalyst in a first riser to produce a first cracked product stream and a spent catalyst stream. The first cracked product stream is separated in a main column. An overhead stream from the main column is separated into a second hydrocarbon stream. The second hydrocarbon stream is contacted with a second stream of fluid catalyst in a second riser to produce a second cracked product stream and a first stream of cool catalyst. A third hydrocarbon stream is obtained from the overhead stream and/or from the second cracked product stream. The third hydrocarbon stream is contacted with a third stream of fluid catalyst in a third riser to produce a third cracked product stream and a second stream of cool catalyst.

Abstract: Processes and apparatuses for activating a dehydrogenation catalyst that include gallium on a support. An additive particle comprising platinum is mixed with the catalyst particles, which may be fresh or deactivated catalyst. The mixture is exposed, in an oxygen containing environment, to a temperature between 650° C. and 1,000° C. The additive particles may be fluidized with the catalyst particles and may active the catalyst in a regenerator.
