    摘要: A method for isobutane alkylation is provided using a fixed-bed catalytic alkylation reactor comprises at least one catalytic flow channel. A feed stream comprising a compound to be alkylated is passed into a flow channel having an alkylation catalyst positioned on at least a portion of the flow channel inner surface in the flow channel downstream region. Olefin is injected into the feed stream at a point beyond a flow channel entrance region whereby the olefin contacts the alkylation catalyst by diffusion to the flow channel inner surface thereby reacting the compound with the olefin and produces an alkylate product.

    摘要: A method of modifying a zeolite catalyst to increase selectivity of the catalyst is achieved by dissolving alumina in a phosphorus-containing acid solution, and treating the zeolite catalyst with the dissolved alumina solution. A method of preparing an aromatic product, such as a xylene product, is also achieved by contacting the modified zeolite catalyst with an aromatic hydrocarbon, such as toluene, and an alkylating agent, such as methanol, under reaction conditions suitable for aromatic alkylation. For xylene products the aromatic hydrocarbon may be toluene and the reaction conditions may be suitable for at least one of toluene methylation and transalkylation.

    摘要: A process for producing an alkylbenzene from an alkylphenyl alcohol involving the steps of: (a) feeding a feed stream containing alkylphenyl a reactor having a catalytic distillation zone; and, (b) concurrently in the reactor (i) contacting the feed stream containing alkylphenyl alcohol with hydrogen in the catalytic distillation zone to convert alkylphenyl alcohol to alkylbenzene over a catalyst containing Group VIII or a Group IB metal; and, (ii) separating alkylbenzene from the reaction mixture by fractional distillation to produce an overhead stream containing alkylbenzene having a reduced concentration of alkylphenyl alcohol than the feed stream from the distillation column reactor. Examples of the alkylphenyl alcohol include cumyl alcohol, phenyl ethyl alcohol, or di(2-hydroxyl 2-propyl)benzene, and that for the alkylbenzene include cumene and di-ethyl benzene, or di(2-hydroxyl-2-propyl)benzene.

    摘要: A method of preparing a xylene product is carried out in a reactor containing a phosphorus-treated ZSM-5-type zeolite catalyst. The method includes initiating a unique start-up of a toluene methylation reaction by contacting the catalyst with a toluene/methanol feed and a cofeed of hydrogen introduced into the reactor at certain start-up conditions. By utilizing the start-up conditions high selectivity for p-xylene can be achieved while providing stable catalytic activity over extended periods.
