摘要： FCC catalyst is regenerated in a process providing increased coke-burning capacity without additional heat evolution or air consumption. The process uses a two-stage regeneration arrangement providing initial coke combustion in a low catalyst density-high efficiency contact zone followed by substantial separation of catalyst and regeneration gas and complete regeneration of catalyst particles in a dense bed regeneration zone. Catalyst and gas flow cocurrent prior to this separation but flow countercurrent after the separation. An effective control scheme for regulating oxygen addition to the final zone is also disclosed. This process is applicable to FCC operations for conventional and residual feedstocks.

摘要： A process for the efficient production of diisopropyl ether where catalytic distillation is used to increase the yield of product beyond thermodynamic equilibrium limitations has been developed. In a hydration zone the propylene in a feedstock is reacted with water in the presence of a catalyst to effect hydration to produce an effluent stream containing at least water, unreacted propylene, and isopropyl alcohol, and then, in an etherification zone, at least a portion of the effluent stream is further reacted by catalytic distillation in the presence of a catalyst to effect reaction of propylene and isopropyl alcohol to form diisopropyl ether while concurrently separating an organic portion containing the diisopropyl ether and an aqueous portion, and collecting the organic portion containing the diisopropyl ether.

摘要： A process for converting a charge stock comprising normally liquid hydrocarbons in a riser conversion zone with an active fluid catalytic cracking catalyst wherein a suspension of hot regenerated active fluid catalytic cracking catalyst in a lift gas comprising hydrocarbons including not more than 10 mole % C.sub.3 and heavier hydrocarbons (calculated on a water-free basis) is passed through a first treatment section of the riser conversion zone at conditions selected to treat the catalyst prior to any contact with the charge stock while simultaneously accelerating the catalyst to a velocity sufficient to provide turbulent dilute flow at the point of contact with the charge stock; thereafter a charge stock is introduced into the suspension of treated particles in the riser conversion zone downstream of the treatment section to form a mixture of catalyst, charge stock and lift gas having the catalyst relatively uniformly distributed therethrough. The charge stock is then reacted with the catalyst in the remaining downstream section of said riser conversion zone at reaction conditions sufficient to effect the desired conversion.

摘要： A process for the production motor fuel components from isoparaffins by dehydrogenation, oligomerization and saturation uses a combination of low severity dehydrogenation, first and second feed input locations and a primary separation column that receives feed and effluent components to deliver a dehydrogenation zone feed and a motor fuel products. A separation column receives the an isobutane input stream and a product containing effluent stream to distill a dehydrogenation zone input steam. The dehydrogenation zone operates at low severity conditions to produce the effluent stream that compliments the operation of an oligomerization zone by delivering an effluent stream that is higher in pressure and contains inert paraffinic diluent materials. The oligomerization effluent passes to a saturation reaction zone that provides a saturated effluent stream. The saturation zone effluent is divided to provide quench to both the oligomerization reaction zone and the saturation zone and saturated motor fuel components to the separation column.

摘要： This invention provides a method of reducing the sulfur oxide emissions from the regenerator of an FCC process that cracks a sulfur containing feedstream. The sulfur oxide emissions are reduced by using an essentially sulfur free lift gas stream to shift the sulfur concentration equilibrium between the product stream from the reaction zone and the flue gas stream from the regeneration zone. Sulfur compounds present in the FCC feed leave the reaction zone as volatile sulfurous gases in the product vapor stream or as adsorbed sulfur compounds on the catalyst. Sulfurous gas in the product vapors is mainly H.sub.2 S. By lowering the concentration of H.sub.2 S that enters the riser with the lift gas the equilibrium reaction of sulfur with hydrogen in the riser is favorably shifted to increase the production of H.sub.2 S and decrease the lay down of sulfur compounds in the coke that forms on the catalyst. As a result less sulfur enters the regeneration zone with the spent catalyst and fewer sulfur oxides are formed during regeneration.
摘要翻译： 本发明提供一种减少裂化含硫进料流的FCC方法的再生器中的硫氧化物排放的方法。 通过使用基本上无硫的提升气流来减少来自反应区的产物流和来自再生区的烟道气流之间的硫浓度平衡。 存在于FCC原料中的硫化合物将反应区置于产物蒸气流中的挥发性亚硫气体或作为催化剂上吸附的硫化合物。 产品蒸气中的亚硫酸气主要是H2S。 通过降低提升气进入提升管的H 2 S的浓度，提升管中硫与氢的平衡反应有利地转移，以增加H 2 S的产生并减少在催化剂上形成的焦炭中硫化合物的沉积。 结果，较少的硫通过废催化剂进入再生区，在再生期间形成较少的硫氧化物。

摘要： A catalyst regeneration process and apparatus for the oxidative removal of coke from a coke contaminated fluid catalyst. The process comprises a high temperature coke combustion zone, a catalyst disengagement zone and an external heat removal zone. A mixture of coke contaminated catalyst, oxygen containing gas, hot regenerated catalyst and cool regenerated catalyst from the heat removal zone are contacted in the high temperature combustion zone, the temperature of which is controlled by adjusting the rate at which catalyst is recycled from the heat removal zone. The temperature of the catalyst-gas mixture is controlled by adjusting the rate at which hot catalyst is recycled from the disengagement zone.

摘要： Olefinic feedstocks which contain catalyst contaminants or poisons such as sulfur containing compounds may be oligomerized to a desired product by effecting the reaction in the presence of an added amount of hydrogen to the feedstock. The catalyst which is employed to effect this oligomerization will remain stable and will not deactivate due to the presence of the aforementioned poisons. The catalyst composite will comprise a porous support which has been impregnated with a catalytically effective amount of an iron group metal compound and, if so desired, a compound containing a metal of the Group IVA of the Periodic Table. In addition, the catalyst composite will also contain in combination therewith, a catalytically effective amount of an alkyl aluminum compound and, if so desired, an aluminum alkoxy or aluminum halide compound.

摘要： A process using selective hydrogenation and HF alkylation in combination that employs a multifunction alkylation stripper for removal of light ends from the selective hydrogenation and a alkylation operations. The process combines the effluent from the selective hydrogenation operation, an isobutane feed stream and a bottoms stream from the HF stripper in the alkylation feed stripper. The feed stripper provides a C.sub.4 -plus bottoms stream that serves as the feed to the alkylation zone and a C.sub.3 -minus overhead that can be recovered as fuel gas. Significant benefit is obtained from this process when processing a mixed olefin feed of C.sub.3 /C.sub.4 hydrocarbons and recovering a high purity C.sub.3 product stream ahead of the selective hydrogenation zone. Another variation of this process allows a C.sub.3 product stream to be withdrawn from the alkylation feed stripper either directly as a sidecut or downstream of an overhead condensor.
