    摘要： Processes for the conversion of both straight- or branched-chain (e.g., paraffinic) as well as cyclic (e.g., naphthenic) hydrocarbons of a hydrocarbon feedstock into value added product streams are disclosed. The processes involve the use of both dehydrogenation and olefin cracking to produce both light olefins and aromatics in varying proportions depending on the feedstock composition and particular processing scheme. The processes are especially applicable to naphtha feedstocks comprising paraffins and naphthenes in the C5-C11 carbon number range.

    摘要： Processes for preparing alkylation aromatic compounds are provided. One process for preparing alkylated aromatic compounds includes reacting an aromatic compound and an olefin in at least one primary alkylation reaction in the presence of a first alkylation catalyst to produce a first effluent. The first effluent is split into a first product-rich stream and a first recycle stream, and the first recycle stream is recycled to the at least one primary alkylation reaction. Unreacted aromatic compound from the first product-rich stream and an additional olefin are reacted in at least one downstream alkylation reaction in the presence of a second alkylation catalyst to produce a second effluent. The second effluent is split into a second product-rich stream and a second recycle stream, and the second recycle stream is recycled to the at least one primary alkylation reaction and, optionally, to the at least one downstream alkylation reaction.

    摘要： A process is presented for the management and control of the 2-phenyl content in a benzene alkylation process. The process includes the use of multiple reactor beds, with benzene flowing through the reactor beds in a sequential manner. The olefin stream is split to two or more portions, and a separate portion is passed to the first reactor bed and second reactor bed. Control of the ratio of the olefin flow splits controls the 2-phenyl content.

    摘要： Processes for preparing alkylation aromatic compounds are provided herein. In an embodiment, a process for preparing alkylated aromatic compounds includes reacting an aromatic compound and an olefin in a first alkylation reaction in the presence of a first alkylation catalyst to produce a first effluent that includes an alkylated aromatic compound and unreacted aromatic compound. Unreacted aromatic compound from the first effluent and additional olefin are reacted in at least one downstream alkylation reaction in the presence of a second alkylation catalyst to produce a second effluent including the alkylated aromatic compound. A recycle stream including the alkylated aromatic compound is recycled from the second effluent to the at least one downstream alkylation reaction and, optionally, the first alkylation reaction. A ratio of the recycle stream to a total mass flow is greater in the at least one downstream alkylation reaction than in the first alkylation reaction.
