    摘要: A catalyst for converting C.sub.2 to C.sub.6 aliphatic hydrocarbons to aromatics is described. The catalyst contains a zeolite, an aluminum phosphate binder and a gallium component. Examples of zeolites which can be used are the ZSM family of zeolites, with ZSM-5 being a specific example. The catalyst is characterized in that it is tolerant to exposure to hydrogen at tempertures of about 500.degree. to about 700.degree. C. The catalyst's tolerance to hydrogen exposure is the result of treating the catalyst with an aqueous solution of a weakly acidic ammonium salt or a dilute acid solution at a temperature of about 50.degree. to about 100.degree. C. for a time of about 1 to about 48 hours, followed by calcination. A process for preparing the catalyst is also described.

    摘要: A novel liquid acid catalyzed alkylation process is disclosed which incorporates a fixed bed of contact material to improve the alkylation reaction zone efficiency. The fixed bed of contact material also allows the process to be efficiently operated at lower acid to olefin mole/mole feed ratios than normally used.

    摘要: A hydrocarbon conversion process is disclosed which extends the useful life of a regenerable zeolite-containing hydrocarbon conversion catalyst. In one aspect of this process, a hydrocarbon feed containing fluorides is passed through a fluoride removal system which reduces the fluoride concentration of the feed to below 100 ppb. The hydrocarbon feed containing less than 100 ppb fluorine is then converted over a regenerable zeolite-containing hydrocarbon conversion catalyst. The zeolite-containing hydrocarbon conversion catalyst is regenerated with an oxygen-containing gas stream as necessary to burn off carbonaceous deposits on the catalyst so as to return the zeolite catalyst to a high level of activity.

    摘要: The present invention relates to a process for producing aromatic compounds from C.sub.2 -C.sub.6 aliphatic hydrocarbons. In this process, a feedstock containing C.sub.2 -C.sub.6 aliphatic hydrocarbons is passed into a reaction zone and into contact with a catalyst zone containing two discrete catalysts. The first catalyst of the discrete catalyst system is comprised in part of a ZSM-5 zeolite component while the second catalyst of the discrete catalyst system is comprised in part of a catalytically active component that is not ZSM-5 which exhibits an acidity lower than that of the first discrete catalyst. A metallic component selected from the Group IIB to IVB Elements of the Periodic Table may be a component of one or both of the discrete catalysts of the instant process as can be a phosphorus-containing alumina component. The discrete catalytic system of the present invention is particularly suited for selectively producing aromatic compounds from C.sub.2 -C.sub.6 aliphatic hydrocarbons while limiting the amount of undesired C.sub.1 and C.sub.2 by-products produced by the process.
