摘要： A process is disclosed for decreasing the emission of airborne pollutants from an oil refinery and for upgrading a paraffinic feedstream to olefins and/or aromatics. Flue gas from a fluid catalytic cracking process catalyst regenerator is cooled to supply the endothermic heat of reaction for a paraffin upgrading reaction, eliminating the need for an additional process furnace. The process further decreases airborne pollutant emissions by upgrading paraffinic fractions which would otherwise be burned as fuel.

摘要： A process is disclosed for the conversion of an aliphatic feedstream in which an oxygen-deficient flue gas is used to directly transfer heat to the primary conversion reaction. Hydrogen, carbon monoxide and carbon dioxide from the primary conversion reactor effluent are converted to methanol or Fischer-Tropsch liquid and may be recycled to the primary conversion reactor. Preferred primary conversion reactions include dehydrogenation and aromatization of aliphatics.

摘要： A process is disclosed for stripping and regenerating a zeolite catalyst at relatively low pressure compared to that of an oligomerization reactor operated with a turbulent fluid-bed at above about 515 kPa (60 psig). The reactor operates either with hydrocarbons in the gas phase, or, under near-critical or supercritical conditions, when they are in the super-dense phase. The super-dense phase exists outside a critical region in the phase envelope of the hydrocarbon mixture in the reactor, under conditions at which a liquid phase may not form (hence "non-liquid"). Whether the fluid-bed reactor is operated in the C.sub.5 -C.sub.10 gasoline producing mode, the C.sub.10.sup.+ distillate mode, or, the C.sub.22.sup.+ lubes mode, continuous operation of a regenerator (for deactivated catalyst withdrawn from the reactor) at relatively low pressure, preferably less than 445 kPa (50 psig), is possible. A variable pressure "lock-stripper" recovers entrained hydrocarbon product from a recirculated catalyst stream before stripped catalyst is regenerated. Without the lock-hoppers, attrition of the catalyst would make the process uneconomical. Depending upon the process conditions, the oligomerized product is either C.sub.5 -C.sub.10 gasoline, or a "heavies" stream (either distillate or lubes), with a minor proportion by weight of gasoline range hydrocarbons.

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). Further, it has been discovered that, following etherification unreacted paraffins in the process can be dehydrogenated to produce C.sub.3 -C.sub.4 olefins which can be recycled to the etherification process. 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 process integrates a first stage tertiary olefin etherification, separation of ether-rich gasoline and a second stage linear olefin etherification to produce a second ether rich gasoline stream.

摘要： A process for the increased production of olefinic gasoline is described incorporating the integration of olefins to gasoline conversion under moderate severity conditions in contact with zeolite type catalyst with oxygenates to olefins conversion. The product of the olefins to gasoline conversion is passed to an olefins to gasoline and distillate (MOGD) conversion zone for distillate production. Liquid recycle requirements, feed throughput and/or the number of MOGD fixed bed stages are reduced for the MOGD process and overall process costs are lowered. The process includes the use of common catalyst handling and regeneration steps for the integrated processes.

摘要： An integrated reactor system for conversion of methanol to ether-containing high octane gasoline and distillate. Methanol is converted to olefins in the presence of zeolite MTO catalyst. C.sub.4 and C.sub.5 olefin fraction is converted to MTBE and TAME in the presence of excess methanol and acid etherification catalyst. Unreacted methanol and hydrocarbons are passed to an olefins to gasoline and distillate oligomerization unit in conjunction with C.sub.3, C.sub.6 and C.sub.7 olefins from the methanol to olefins unit whereby distillate and LPG products are produced. Gasoline products from the oligomerization unit are passed to the etherification unit whereby an ether-rich gasoline fraction is separated.

摘要： Apparatus for regenerating zeolite-type catalyst used in fixed bed hydrocarbon conversion processes, such as the conversion of olefins to gasoline and diesel fuel. Regeneration is achieved using a portion of a flue gas stream to regenerate catalyst and preheat feedstock. Economies in equipment and operation are realized by employing a once-through configuration for the regenerator gas stream.
