The production of linear alkylbenzene from a natural oil is provided. A method comprises the step of deoxygenating the natural oils to form a stream comprising paraffins. The paraffins are dehydrogenated to provide mono-olefins. Then, benzene is alkylated with the mono-olefins under alkylation conditions to provide an alkylation effluent comprising alkylbenzenes and benzene. Thereafter, the alkylbenzenes are isolated to provide the alkylbenzene product.

A liquid phase dehydrogenation process is described. The process includes reacting a liquid feed stream containing C10 to C28 paraffins and dissolved hydrogen in a dehydrogenation reaction zone in the presence of a dehydrogenation catalyst under liquid dehydrogenation conditions to dehydrogenate the paraffins to form a liquid dehydrogenation product stream comprising monoolefins, unreacted paraffins, and hydrogen, wherein the monoolefins in the product stream have 10 to 28 carbon atoms.

Methods and systems are provided for converting methane in a feed stream to acetylene. The method includes removing at least a portion of nitrogen from a hydrocarbon stream. The hydrocarbon stream is introduced into a supersonic reactor and pyrolyzed to convert at least a portion of the methane to acetylene. The reactor effluent stream may be treated to convert acetylene to another hydrocarbon process. The method according to certain aspects includes controlling the level of nitrogen in the hydrocarbon stream.

Apparatuses and methods for producing linear alkylbenzene products from renewable oils are provided. An exemplary method includes deoxygenating the renewable oil in a deoxygenation zone to form paraffins. The method fractionates the paraffins to form first and second fractions. The method processes the first fraction of paraffins in a reforming zone to form a reformate stream and recovers a first hydrogen stream from the reforming zone. The method includes forming a LAB stream in a LAB production zone from the second fraction of paraffins and a portion of the reformate stream. Further, the method includes recovering a second hydrogen stream in the LAB production zone and recycling the first hydrogen stream from the reforming zone and the second hydrogen stream from the LAB production zone, wherein substantially all hydrogen recovered from the reforming zone and the LAB production zone is recycled.
摘要:
The process of producing an alkylbenzene compound from the alkylation of an aromatic compound with an acyclic monoolefin is an exothermic process. A process for maintaining a relatively constant temperature improves the process and allows for controlling the yields. The process includes recycling a compound through the reactor that is relatively inert, but will moderate the exotherm, while maintaining the 2-phenyl content of the final alkylbenzene product.

摘要:
A method of making dialkylaromatics as a primary product is described. The design involves a dual reaction zone system, both reaction zones containing alkylation catalysts. The olefin feed is split into two portions (or two feeds are used), the first portion being fed to a first alkylation reaction zone and reacted with a first olefin. The other portion of olefin is reacted in a second reaction zone with the linear alkylaromatics formed in the first reaction zone to form the dialkylaromatics.
