摘要: A multi-step hydrocarbon conversion process for producing gasoline from propane or butane is disclosed. The feed hydrocarbon is passed into a dehydrogenation zone and the entire dehydrogenation zone effluent including hydrogen and light by-products is then passed into a catalytic condensation zone wherein the resulting olefins are converted into dimers and trimers. The condensation zone effluent stream is passed into a separation zone in which the dimers and trimers are concentrated into a product stream, with unconverted feed hydrocarbon and hydrogen being recycled to the dehydrogenation zone.

摘要: A multi-step hydrocarbon conversion process for producing gasoline from propane is disclosed. Propane is passed into a dehydrogenation zone and the entire dehydrogenation zone effluent is then passed into a catalytic condensation zone wherein propylene is converted into C.sub.6 and C.sub.9 hydrocarbons. The condensation zone effluent, a stripper overhead stream and an absorber bottoms stream are commingled and then separated into vapor and liquid portions. The liquid is passed into the stripper, and the vapor portion is contacted with stripper bottoms liquid in an absorber. The absorber overhead stream is contacted with liquid propane in a second absorber to remove C.sub.6 hydrocarbons and is then recycled to the dehydrogenation zone. Depropanizing a portion of the stripper bottoms yields the liquid propane and a gasoline product.

摘要: A multi-step hydrocarbon conversion process for producing gasoline from butane is disclosed. Butane is passed into a dehydrogenation zone and the entire dehydrogenation zone effluent is then passed into a catalytic condensation zone wherein butylene is converted into C.sub.8 and C.sub.12 hydrocarbons. The condensation zone effluent, a stripper overhead stream and an absorber bottoms stream are commingled and then separated into vapor and liquid portions. The liquid is passed into the stripper, and the vapor portion is contacted with stripper bottoms liquid in an absorber. The absorber overhead stream is contacted with liquid butane in a second absorber to remove C.sub.8 hydrocarbons and is then recycled to the dehydrogenation zone. Debutanizing a portion of the stripper bottoms yields the liquid butane and a gasoline product.

摘要: A process for producing gasoline from a charge stream comprising a mixture of butanes and butylenes is disclosed. The quality of a product alkylate is improved by increasing the butene-2 content of an alkylation zone feed stream. A first portion of the charge stream is passed into a dimerization zone in which isobutylene is reacted with normal butylenes, with butene-1 being reacted to a greater extent than butene-2. A C.sub.8 hydrocarbon-containing product stream and a C.sub.4 stream having a higher butene-2 concentration than the charge stream are recovered from the dimerization zone. This high butene-2 content C.sub.4 stream is admixed with a second portion of the charge stream and passed into an alkylation zone wherein butylenes are reacted with isobutane to yield a second product stream containing C.sub.8 hydrocarbons.

摘要: A process for the isomerization of normal olefinic hydrocarbons is disclosed. The feed stream is passed through a first reaction zone and is then cooled sufficiently to cause the condensation of from about 1 to 25 mole percent of the hydrocarbons in the isomerization zone effluent stream. The uncondensed portion of the effluent of the first reaction zone is heated and passed through a second reaction zone which is maintained at a lower temperature than the first reaction zone. The product isomer is recovered from the effluent of the second reaction zone.

摘要: A process for the alkylation of aromatic hydrocarbons using a solid phosphoric acid catalyst in which liquid phosphoric acid is removed from the bottoms stream of the rectification column to which the alkylation zone effluent is charged. The acid is removed by passing the bottoms stream into a settling vessel operated at a lower pressure and temperature than the bottom of the rectification column.

摘要: A process to reduce utility consumption in the catalytic alkylation of benzene with propylene to form cumene. Propylene and benzene are reacted in an alkylation reaction zone, the effluent of which is divided into two portions, the first being recirculated to the inlet of the reaction zone and the second being passed into a separation zone wherein cumene product, di- and triisopropylbenzene and excess benzene are separated. A portion of the excess benzene is recycled to the inlet of the alkylation reaction zone, and a second portion is admixed with di- and triisopropylbenzene and passed into a transalkylation zone, the effluent of which is introduced into the separation zone. Utility consumption is reduced compared to prior art processes, as a result of a reduction of the portion of excess benzene separated and recycled to the alkylation reaction zone.
