摘要： A process for making linear alkyl aromatics is described. The process involves preparing the paraffin feed by dehydrogenating normal paraffins, selectively hydrogenating any diolefins, and adsorbing any aromatics to form an olefin feed. The olefin feed is contacted with an aromatic feed in the presence of an ionic liquid catalyst to form a mixture of alkylated aromatics. The ionic liquid catalyst is separated from the mixture of alkylated aromatics by gravity, and any ionic liquid retained in the alkylated aromatics is removed by adsorption or extraction. The mixture of alkylated aromatics is then separated into monoalkylated aromatics and dialkylated aromatics.

摘要： In a process for producing cyclohexylbenzene, benzene is reacted with cyclohexene under alkylation conditions effective to produce an alkylation effluent comprising cyclohexylbenzene and a polycyclohexylbenzene. A first feed comprising at least a portion of the alkylation effluent is then fed to a first separation device, where the first feed is separated into at least a first fraction containing cyclohexylbenzene and a second fraction containing the polycyclohexylbenzene, the second fraction also comprising an oxygenated hydrocarbon. At least a portion of the oxygenated hydrocarbon is removed from at least a portion of the second fraction in a second separation device to obtain a second feed. The second feed may then be reacted in a transalkylation or dealkylation reactor to convert at least part of the polycyclohexylbenzene to additional cyclohexylbenzene.

摘要： This invention is for a catalyst for conversion of hydrocarbons. The catalyst is a germanium zeolite, such as Ge-ZSM-5, on which at least two metals, platinum and at least one other metal selected from Group 7, Group 8, Group 9, Group 10 and tin, are deposited on the germanium zeolite. Examples of the other metal are iridium, rhenium, palladium, ruthenium, rhodium, iron, cobalt and tin. The catalyst is prepared by synthesizing a germanium zeolite; depositing platinum and at least one other metal on the germanium zeolite; and calcining after preparation of the zeolite, before depositing the metals or after depositing the metals. The catalyst may be used in a process for the conversion of hydrocarbons, such as propane to aromatics, by contacting the catalyst with a hydrocarbon stream containing alkanes, olefins and mixtures thereof having 2 to 12 carbon atoms per molecule and recovering the 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.
