摘要： An integrated process for the production of ether-rich liquid fuels containing MTBE and TAME by etherifying a hydrocarbon feedstock containing C.sub.4 + isoalkenes in the presence of a high stoichiometric excess of lower alkyl alcohol. Unreacted alcohol and olefins are passed to a zeolite catalyzed conversion reactor under olefinic and oxygenates conversion condition whereby gasoline and light hydrocarbons are produced. The light hydrocarbon fraction comprising C.sub.4 -C.sub.5 paraffins is dehydrogenated and C.sub.4 -C.sub.5 olefins are recycled to the etherification reactor.

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 conversion is achieved by utilizing the differing reactivity of tertiary olefins under selected conditions compared to linear olefins in the catalyzed etherification processes. The discovery has been made that unreacted olefins from the etherification reactions can be converted to gasoline boiling range hydrocarbons by contacting them with zeolite catalyst at elevated temperature. Further, it has been discovered that unreacted paraffins in the integrated process can be dehydrogenated to produce C.sub.3 -C.sub.4 olefins which can be recycled to the etherification process.

摘要： A technique for converting olefinic light hydrocarbons to ether-rich liquid fuels and olefinic gasoline including etherification, olefin upgrading and transhydrogenation operations. The preferred process includes: reacting a fresh hydrocarbon stream containing C.sub.4 + iso-alkene with lower aliphatic alcohol in an etherification zone in contact with an acidic etherification catalyst under etherification conditions whereby an effluent stream containing C5+ tertiary-alkyl ether is produced; separating the etherification effluent stream to provide a first liquid stream comprising C5+ ether and a second stream comprising unreacted alcohol and C4+ hydrocarbons; contacting the second stream with acidic metallosilicate catalyst for conversion of oxygenates and olefins under olefin oligomerization and isomerization conditions at elevated temperature; separating oligomerization effluent to recover an intermediate hydrocarbon stream rich in C.sub.4 + paraffinic hydrocarbon, a light gas stream, and a liquid product stream comprising C.sub.6 + olefinic gasoline; contacting the C.sub.4 + intermediate hydrocarbon stream with lower alkene in the presence of transhydrogenation catalyst whereby C.sub.4 + paraffin is converted to C4+ olefin, including iso-alkene; separating transhydrogenation effluent to recover C4+ olefin containing iso-alkene; and passing at least a portion of iso-alkene to the etherification zone for co-conversion with fresh hydrocarbon and alcohol to produce tertiary-alkyl ether.

摘要： A process is provided for upgrading the olefinic gasoline by-product of low-severity medium-pore zeolite catalyzed hydrocarbon conversion processes including catalytic dewaxing and olefin oligomerization. The olefinic gasoline stream is upgraded in a high-severity catalytic conversion process which may be carried out in a catalytic cracking unit primary or secondary riser reactor or in a second medium-pore zeolite-catalyzed reaction zone. The olefinic gasoline stream may be mixed with a C.sub.2 -C.sub.7 aliphatic stream before upgrading the mixture in the high-severity catalytic conversion process. Examples of such low-severity medium-pore zeolite catalyzed hydrocarbon conversion processes include distillate and lubricant dewaxing as well as olefin oligomerization.

摘要： A turbulent super-dense fluid-bed of a medium pore zeolite metallosilicate catalyst is operated at low WHSV, outside a critical region in the phase diagram of the hydrocarbon mixture in the reactor, at or above conditions of pressure P.sub.max and temperature T.sub.max at which a liquid phase may not form. The result is oligomerization of a "light gas" predominantly C.sub.3 -C.sub.5 olefin feed, the remainder being mainly C.sub.3 -C.sub.5 lower alkanes. The oligomerized product is a "heavies" stream, namely, distillate and lube oil range hydrocarbons, with a minor proportion by weight of gasoline range hydrocarbons. The reactor may be operated in either a C.sub.1.sup.+ distillate mode, or, a C.sub.22.sup.+ lubes mode. The superdense fluid bed with a density, measured at the bottom of the reaction zone, greater than 500 kg/m.sup.3, and operates at a temperature in the range from about 204.degree. C. (400.degree. F.) to about 371.degree. C. (700.degree. F.), and a pressure in the range from about 2857 kPa (400 psig) to about 13880 kPa (2000 psig) or even higher. This unique process provides per pass conversion of olefins, and selectively to C.sub.5.sup.+ hydrocarbons, each in excess of 80%.
