    摘要: A process and reactor apparatus are disclosed for upgrading paraffinic feedstocks to olefinic and/or aromatic products. Hydrogen diffuses through a selectively permeable membrane from the reaction zone into a combustion zone where it reacts exothermically with an oxygen-containing fluid to supply at least a portion of the endothermic heat of reaction for the paraffin upgrading process. Additionally, in-situ separation of by-product hydrogen from the reactant mixture in the reaction zone increases yield of valuable olefinic and aromatic products.

    摘要: The invention is directed to a multimetallic catalyst and its use in a reactor system in a C9+ aromatics conversion process in order to reduce the saturation of aromatic species, reduce the production of C6+ non-aromatics byproducts, and achieve higher benzene purity. The multimetallic catalyst exhibits improved selectivity towards aromatic hydrocarbons in comparison to a traditional Pt/ZSM-5 catalyst and comprises ZSM-5, a Group 6-10 metal, and an additional metal not in Group 6-10. The C9+ aromatics conversion reactor system comprises a top bed containing the multimetallic catalyst for dealkylation of ethyl and propyl side chains, a second bed containing a catalyst comprising a hydrogenation component for transalkylation, and an optional third bed containing a catalyst without a hydrogenation component to convert non-aromatic hydrocarbons to gas products.
