摘要： The benzene concentration in the gasoline pool of a petroleum refinery is decreased by alkylation of the benzene in a catalytic dewaxing reactor using the olefinic by-products from the dewaxing reaction as alkylating agents. The catalytic dewaxing is preferably carried out in the presence of an intermediate pore size zeolite such as ZSM-5 using a distillate or lube boiling range dewaxing feed. The benzene rich feed preferably contains less than about 2% C.sub.7+ aromatics in order to reduce alkylation of non-objectionable species in the reformate.

摘要： A petroleum refinery process for the production of alkyl aromatic hydrocarbons from a C.sub.4.sup.- fuel gas containing light olefins including ethene and propene and catalytic reformate containing C.sub.6 to C.sub.8 aromatics. The C.sub.4.sup.- fuel gas is contacted with the catalytic reformate at a weight ratio of aromatics to olefins of 10:1 to 15:1 over a zeolite catalyst under process conditions to alkylate the C.sub.6 to C.sub.8 aromatics, particularly benzene, in the reformate with ethene and propene in the C.sub.4.sup.- fuel gas to form alkyl aromatic hydrocarbons. The reaction is carried out in a riser reactor having multiple olefin feed injection points in the riser section of the reactor.The catalytic reaction also causes the conversion of a small amount of light olefins in the fuel gas to coke by-product and the deposition of coke on the catalyst. The deposited coke causes the partial deactivation of the catalyst. A portion of the partially deactivated catalyst is continuously or intermittently withdrawn from the riser reactor and regenerated in a catalyst regenerator by contacting the catalyst with hydrogen containing regeneration gas or by contacting the catalyst with an oxygen containing regeneration gas to remove substantially all of the coke from the catalyst. The regenerated catalyst is introduced in the riser reactor and contacted with fresh feed.

摘要： Isopentene, or isoamylene, conversion to methyl tert-amyl ether can be substantially improved while high conversion of isobutylene to methyl tert-butyl ether can be maintained by carrying out the overall etherification process with alkanol in a staged manner, wherein the first stage is methanol etherification of a C.sub.5 +, or C.sub.5, hydrocarbon feedstream rich in isoamylene and the second stage is etherification to produce MTBE and additional TAME from a C.sub.4 +, or C.sub.4, feedstream. Unreacted methanol and hydrocarbons from the first etherification are uniquely separated by fractionation from the TAME product by using the second stage C.sub.4 + feedstream as a reflux stream to the fractionator and passed to the second etherification zone. Products from the second etherification zone are separated by distillation to produce MTBE, TAME and C.sub.5 +, or C.sub.5, hydrocarbons as a bottom stream.

摘要： Methanol or other alcohol is converted to high octane gasoline components by an integrated process wherein crude aqueous alcohol feedstock is extracted with a liquid extractant stream containing C.sub.4.sup.+ iso-olefin and reacted to form tertiary-alkyl ethers, such as MTBE. The aqueous raffinate is converted to predominantly gasoline range liquid hydrocarbons in a MTG catalytic reactor, with byproduct alkanes rich in propane and isobutane. Dehydrogenation of C.sub.3 -C.sub.5 alkanes from the MTG unit provides propene and isobutene reactants for subsequent etherification steps. Propene from the MTG dehydrogenation step is reacted with water to produce di-isopropyl ether, which may be blended with MTBE and C.sub.6.sup.+ MTG hydrocarbons to produce high octane gasoline. Isobutylene and isoamylenes from the MTG dehydrogenation step can be removed and recycled as a liquid extractant stream.

摘要： A reactor system contained in a fired heater and a hydrocarbon upgrading process are discosed for the concurrent conversion of a hydrocarbon feedstock and the regeneration of a deactivated catalyst. An effluent product slipstream from a set of operating reactors is used to hydrogen-regenerate deactivated catalyst in another set of reactors. Flue gas withdrawn from the fired heater stack is used as a purge and/or carrier gas during oxygen-regeneration of the catalyst.

摘要： An improved fluid-bed reaction process and apparatus are disclosed in which feedstock is preheated and may be at least partially converted by contacting the feedstock with spent catalyst in a preheat zone. Additional benefits include a reduction in catalyst poisons and coke production in the reaction zone. By contacting the fresh feed with hot spent catalyst, at least a portion of the coke which would otherwise form in the reactor is deposited on the spent catalyst. Temporary catalyst poisons are also sorbed onto the spent catalyst. The spent catalyst is then withdrawn from the preheat zone, stripped of entrained hydrocarbon and regenerated.

摘要： A catalytically dewaxed lubricating oil of improved oxidation stability is produced by catalytically dewaxing and hydrotreating the dewaxed product with a hydrotreating catalyst which has been oxidatively regenerated. The use of oxidative regeneration provides a hydrotreating catalyst which effectively sorbs aromatic components, especially the polycyclic aromatic liquids formed during the hydrogen activation of the dewaxing catalyst which pass out of the dewaxing reactor during the initial stages of each dewaxing cycle.
