    摘要: A process is disclosed for converting a light hydrocarbon feedstock that contains a mixture of linear and branched olefins to ether-rich high octane gasoline streams that include tertiary alkyl and isoalkyl ethers such as MTBE, TAME, methyl isopropyl ether (MIPE), and methyl sec-butylether (MSBE). The process involves initially etherifying the tertiary olefins with a lower alcohol in the presence of an ion exchange resin catalyst, and then etherifying the linear olefins in the presence of a zeolite catalyst, such as zeolite beta. The unreacted olefins from the etherification reactions are converted to gasoline boiling range hydrocarbons by oligomerization with a zeolite catalyst, such as ZSM-5.

    摘要: A process for the production of high octane gasoline rich in aromatics but containing a relatively low concentration of benzene comprises the separation of C₆ fraction of the gasoline feedstock into n-hexane and other C₆ isomers. The n-hexane and C₇+ streams are catalytically reformed to produce a reformate with a diminished yield of benzene. The reformate is separated and the C₆- reformate fraction containing benzene is alkylated employing a zeolite catalyst such as ZSM-5 and preferably methanol or propylene as the alkylating agent. The alkylate comprises high octane C₇+ alkylaromatics.

    摘要: Lower alkanes are converted to olefins in a 'third bed' external catalyst cooler (ECC) in which hot catalyst, from a first regenerator ('second best') operating in conjunction with a fluid catalytic cracker ('first bed'), thermally cracks and dehydrogenates the alkanes. Because this is an endothermic reaction, the catalyst is autogeneously cooled before it is recirculated to the FCC regenerator. The cracking catalyst is the catalyst of choice in the FCC reactor. Maximum conversion of alkanes to olefins is sought, and can be maintained because the FCC regenerator burns the coke made during alkane dehydrogenation. The olefins produced are then oligomerized in an oligomerization reactor ("fourth" bed) operating in conjunction with a second regenerator ("fifth" bed) to produce a gasoline range stream. The interrelataed operation of this combination of five fluid beds is tailored to convert all available low value alkanes, to olefins which are generally in high demand for several uses, particularly to make high value gasoline.
