摘要： A technique for continuous conversion of diene-containing aliphatic hydrocarbon feedstock to heavier hydrocarbon products wherein the feedstock is contacted at elevated temperature under endothermic high severity reaction conditions with a fluidized bed of acidic zeolite fine catalyst particles, comprising methods and means for:maintaining the fluidized catalyst bed in a vertical reactor having a turbulent reaction zone by passing vapor upwardly through the reaction zone at a velocity greater than dense bed transition velocity to a turbulent regime and less than transport velocity for the average catalyst particle;feeding a continuous stream of feedstock into the reaction zone, said feedstream comprising sufficient C.sub.3.sup.+ alkanes to require net endothermic reaction conditions;withdrawing a portion of coked catalyst from the reaction zone, oxidatively regenerating the withdrawn catalyst, heating the catalyst substantially above process temperature in the fluidized bed reactor, and returning hot regenerated catalyst to the reaction zone at a rate to control catalyst activity and reaction temperature under conditions of reaction severity to effect feedstock conversion to an aromatics-rich hydrocarbon effluent stream; andseparating an aromatics-rich product from the fluidized bed effluent stream.Aromatics yield is increased by recovering a recycle stream comprising C.sub.5.sup.+ aliphatic hydrocarbons from the fluidized bed effluent stream for further conversion in the fluidized bed to increase aromatics product yield.

摘要： A multistage process for producing isoalkyl ethers from lower aliphatic oxygenate feedstock, such as methanol. Feedstock is catalytically converted in a primary catalyst stage at elevated temperature in contact with zeolite catalyst to predominantly C.sub.2 -C.sub.7 lower olefins comprising isobutylene and isoamylene, by-product water and a minor amount of C.sub.8.sup.+ hydrocarbons, followed by fractionation of the C.sub.2 -C.sub.7 olefins to recover a C.sub.2 -C.sub.3 -rich recycle stream for further catalytic conversion in the primary stage. C.sub.4 -C.sub.7 olefins are passed to a second catalytic etherification stage for reaction of isoalkenes with methanol to produce methyl tertiary-butyl ether, methyl isoamylether and higher isoalkyl ethers. The second stage effluent may be fractionated to recover an ether product, C.sub.5.sup.+ hydrocarbon liquid product, and unreacted butenes. Advantageously, the unreacted butenes are further reacted with isoparaffin in a third catalytic stage under acid catalysis alkylation conditions, and fractionated to recover C.sub.6.sup.+ alkylate liquid, liquid hydrocarbon product. The ethers may be blended with at least one C.sub.6.sup.+ hydrocarbon to produce high octane gasoline.

摘要： A process and apparatus are disclosed for achieving turbulent or fast fluidized bed regeneration of spent FCC catalyst in a bubbling bed regenerator having a stripper mounted over the regenerator and a stripped catalyst standpipe within the regenerator. A coke combustor vessel is immersed in, and in open fluid communication with, the bubbling dense bed of the existing regenerator vessel. Spent catalyst is discharged into the coke combustor, mixes with hot regenerated catalyst which flows into the coke combustor, and regenerated with combustion air in a turbulent or fast fluidized bed. Catalyst and flue gas are discharged up into a dilute phase transport riser, preferably into cyclone which separate hot regenerated catalyst from flue gas. Regenerated catalyst is collected in the bubbling dense bed surrounding the coke combustor, and some is recycled by flowing into the coke combustor for direct contact heat exchange.

摘要： A circulating fluid bed combustion (CFBC) unit, which burns a carbon and nitrogen containing fuel to produce heat and flue gas comprising NO.sub.x, operates with reduced emissions of NO.sub.x from the flue gas by adding to the circulating fluid bed a catalytically effective amount of a DeNO.sub.x catalyst, such as bismuth oxide on a silica/alumina support. The DeNO.sub.x catalyst may circulate freely with the circulating inventory of particulates in the CFB, or can be disposed on a heavier particle which "slips" and has an extended residence time in the combustion zone where the carbonaceous fuel is burned. A CO combustion promoter, such as Pt on silica/alumina may also be present.
