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: The present subject matter relates generally to methods for hydrocarbon conversion. More specifically, the present subject matter relates to methods for integrating reforming and dehydrocyclodimerization, which are both catalytic processes. While dehydrocyclodimerization takes two or more molecules of a light aliphatic hydrocarbon, such as propane or propylene, to form a product aromatic hydrocarbon and hydrogen, platforming takes C6 and higher carbon number reactants, primarily paraffins and naphthenes, to convert to aromatics and hydrogen. This integration enables an opportunity to recombine the light aliphatic hydrocarbon from the platforming process into a more desirable aromatics species.

Abstract: A process is disclosed for an improved catalyst reduction process. The reduction zone is divided into two zones. The first reduction zone is a drying zone where a substantial portion of the chemisorbed water is removed at lower severity conditions. After the catalyst is partially dried, the partially dried catalyst moves to the second reduction zone to be reduced and further dried at higher severity conditions. The flow rate and the reduction zone are designed to ensure there is minimal water left on the catalyst by the time it leaves the reduction zone. This design eliminates high levels of H2O at high severity conditions in both the reduction zone and the reactors.

Abstract: The present subject matter relates generally to methods for selectively saturating the unsaturated C2-C4. More specifically, the present subject matter relates to methods for saturating butadiene and butenes from a hydrocarbon stream before it is combined with a fresh feed and enters a reaction zone. Removing the unsaturates from the hydrocarbon stream before the hydrocarbon stream enters the reaction zone prevents the reactor internals from coking.
