Abstract: Apparatus and processes herein provide for converting hydrocarbon feeds to light olefins and other hydrocarbons. The processes and apparatus include, in some embodiments, feeding a hydrocarbon, a first catalyst and a second catalyst to a reactor, wherein the first catalyst has a smaller average particle size and is less dense than the second catalyst. A first portion of the second catalyst may be recovered as a bottoms product from the reactor, and a cracked hydrocarbon effluent, a second portion of the second catalyst, and the first catalyst may be recovered as an overhead product from the reactor. The second portion of the second catalyst may be separated from the overhead product, providing a first stream comprising the first catalyst and the hydrocarbon effluent and a second stream comprising the separated second catalyst, allowing return of the separated second catalyst in the second stream to the reactor.

Abstract: Methods for making higher-octane fuel components from a feed stream of C8+ paraffins, including catalytically cracking the C8+ paraffins using a Zeolite catalyst to produce a reaction product of mid-chain paraffins and olefins and short-chain paraffins and olefins. The reaction product comprises liquid phase paraffins having an increased Octane Value over the feed stream paraffins. The reaction product further comprises a gas phase of short-chain paraffins which are separated from the liquid phase. In embodiments, the short chain olefins are hydrogenated to form mid-chain paraffins and a gas phase containing short-chain paraffins.

Abstract: A catalytic cracking process includes the following steps: i) subjecting a heavy feedstock oil to flail catalytic cracking; ii) separating the catalytic cracking reaction product obtained from step i) to obtain a catalytic cracking gasoline and a catalytic cracking light cycle oil; iii) splitting the catalytic cracking gasoline to obtain a light gasoline fraction, a medium gasoline fraction and a heavy gasoline fraction; iv) subjecting the catalytic cracking light cycle oil to hydrogenation to obtain a hydrogenated light cycle oil); v) mixing a portion of the light gasoline fraction with at least a portion of the hydrogenated light cycle oil to obtain a mixed fraction; vi) subjecting the mixed fraction to catalytic cracking; and vii) subjecting a portion of the medium gasoline fraction to flail catalytic cracking. The process is capable of producing more catalytic cracking gasoline, reducing the olefin content of the catalytic cracking gasoline, and increasing its octane number.
