摘要： A process for regenerating solid particulate catalyst used in fixed bed hydrocarbon conversion processes, such as the shape selective zeolite 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.

摘要： Valuable product yield and catalyst useful life are improved by regenerating spent catalyst at temperatures below those maintained in the reaction zone. Relatively cold regenerated catalyst is then preheated and reactor effluent product is quenched by directly contacting the regenerated catalyst with hot reactor effluent product. The quenching step minimizes undesirable thermal cracking of valuable product to C.sub.2 -light gas. The process and apparatus are useful both in aromatization and dehydrogenation of aliphatic hydrocarbons.

摘要： A high pressure process is disclosed for oligomerizing a lower olefin-containing feed to produce distillate or lubes without having to regenerate spent catalyst. Directly coupling the operation in tandem of a MOG (Mobil Olefin to Gasoline) riser reactor and a fluid bed MODL (Mobil Olefin to Distillate or Lubes) reactor, each containing a medium pore size siliceous metallosilicate crystalline shape selective zeolite catalyst, and each operating so that the effluent from each leaves in the super-dense phase, produces the desired product. The MOG riser operates in the transport regime at sufficiently high severity so as to make a "distillate-rich" gasoline effluent with spent catalyst from the MODL reactor. The MODL reactor operates in the turbulent regime at low severity, with catalyst having a lower coke content than that of riser catalyst, to produce a major portion by wt of either distillate or lubes, depending upon the chosen mode of operation, with excellent per pass conversion of olefins. Substantially no catalyst from the riser goes to the fluid bed, while a minor portion of the inventory of catalyst in the fluid bed is either intermittently or continuously withdrawn as a slipstream. This slipstream may be drawn down into the riser, or discharged to a FCC unit, or both. A gasoline/distillate splitter separates gasoline from distillate and/or lubes made in the MODL reactor. A portion of the gasoline is purged, but the remainder is recycled to the inlet of the MODL reactor to quench the effluent from the MOG riser before it is introduced into the MODL reactor. This control of temperature, and avoiding the use of a regenerator provides an economic process.

摘要： Alkanes, preferably lower alkanes, are converted to olefins in a `third bed` external catalyst cooler (ECC) in which hot catalyst from a first regenerator (`second bed`) 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. The conversion of alkanes to olefins is tailored to provide a mixed feed for an aromatization reactor (`fourth bed`) which feed is proportioned to provide a substantially heat-balanced reaction in the aromatization reactor, that is, requiring no additional heat other than that which is provided by the feed and the heat of reaction. A second regenerator (`fifth bed`) is provided for the aromatization reactor, preferably in a moving bed reactor system. This reactor produces a predominately aromatic hydrocarbon stream. The interrelated operation of this combination of five beds is tailored to convert all available low value alkanes and olefins to produce more valuable benzene, toluene and xylenes in the aromatic stream.

摘要： An improved olefin upgrading technique has been developed for increasing production of premium heavy hydrocarbons, such as distillate fuel, from lower olefinic feedstock. During recovery and recycle of intermediate range hydrocarbons products, a process has been found for withdrawing a fraction rich in C.sub.5 -C.sub.9 gasoline range olefinic hydrocarbons from the oligomerization reactor effluent stream. By separating the reaction effluent in a multistage distillation system, fractionation feed can be separated into a heavier bottoms stream rich in C.sub.10+ hydrocarbons and a light hydrocarbon overhead, while withdrawing a liquid stream as an overflash fractionation stream rich in intermediate hydrocarbons. The overflash stream is combined to form a portion of the recycle stream to the reactor, thereby providing a more efficient and lower cost recovery process.

摘要： Lower alkanes are converted to olefins in a `third bed` external catalyst cooler (ECC) in which hot catalyst, from the regenerator (`second bed`) 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. The most evident benefit of using the ECC is that it eliminates internal regenerator coils for steam regeneration. Among several additional benefits is that the ECC allows flexibility in design of its fluid `third bed` for optimum weight hourly space velocity (WHSV), and control of the dehydrogenation temperature so as to get maximum conversion of alkanes. This conversion can be maintained because the FCC regenerator burns the coke made during alkane dehydrogenation. The ECC also permits control of the temperature at which the FCC regenerator operates so as to facilitate processing heavier than conventionally used feedstock in the FCC unit resulting in better earnings.

摘要： An integrated process for the production of alkylate and etherate rich high octane gasoline streams comprising the etherification to produce MTBE and TAME in the presence of a high stoichiometric excess of methanol followed by the conversion of unreacted methanol in contact with zeolite-type catalyst in the presence of aromatics to produce alkylated aromatics in gasoline. The light paraffinic effluent from the methanol conversion zone is reacted in contact with zeolite catalyst under aromatization conditions to produce an aromatics feedstream for the methanol conversion reaction. A supplemental olefinic feedstream is provided to the methanol conversion zone after optionally serving as stripping medium for the separation of methanol and etherate-rich C.sub.5 + gasoline from the etherification reaction.
