    摘要: A catalytic cracking process for converting heavy, metals laden feed to lighter products is disclosed. The catalyst regenerator is operated under relatively reducing conditions, to produce a flue gas containing at least 1 mole % carbon monoxide. An additive, preferably alumina, is added to the circulating catalyst inventory to selectively sorb metal contaminants in the feed. The reducing conditions in the catalyst regenerator minimize formation of highly oxidized forms of vanadium, permitting higher vanadium levels to be tolerated on the cracking catalyst. The additive material has a greater affinity for vanadium than the cracking catalyst, and absorbs a disproportionate amount of metals in the feed. Preferably a soft, friable, alumina additive is used which results in the production of alumina fines rich in vanadium, which are discharged from the unit with catalyst fines. The process works especially well in fluidized catalytic cracking processes, with removal of vanadium laden alumina fines from the FCC regenerator with the regenerator flue gas.

    摘要: A process for removing catalyst fines from slurry oil is disclosed. A settling reagent, such as coal, alumina, or coke, is added to a fines containing heavy oil bottoms product from a fractionator downstream of a catalytic cracking unit. The settling reagent promotes rapid settling and removal of fines from heavy oil product. Settling may be performed in a slurry settler, or a centrifuge. A catalytic cracking process for heavy, metals laden oil is also disclosed using a settling reagent to clarify slurry oil, then recycling settled settling reagent to contact the heavy oil in the catalytic cracking process.

    摘要: A catalytic cracking process operates with a getter additive present where hot catalyst meets heavy metals laden crude. The getter additive is a material which is selective for metals, and has a particle size/density such that the getter additive remains in the FCC unit for no more than 24 hours, and preferably is removed within one hour or less. Addition of 1-5 weight percent alumina having an average particle size of 10-40 microns will remove much of the metal content from the feed, and the metals laden additive will itself be rapidly removed from the FCC unit preventing migration of metal or degradation of the cracking operation due to the presence of metal. Preferably the additive is fine particles which are mixed with the hydrocarbon feed to the unit.

    摘要: Combustible carbonaceous particles such as particles of sponge coke or coal are incorporated with the circulating inventory of cracking catalyst in a fluid catalytic cracking unit. The carbonaceous particles selectively sorb metal contaminants in the feed, thereby extending catalyst life, and they also serve to reduce NO.sub.x emissions in certain instances. The sorbed metals values may be recovered as the carbonaceous particles are burned.

    摘要: A continuous online process for rejuvenating whole stream of contaminated lean sulfolane in an extraction system is provided. In particular, a rejuvenator is installed in the solvent circulation loop to remove the contaminants continuously to keep the solvent clean, effective and less corrosive. Specifically, the rejuvenator comprises a high pressure vessel with a removable cover and a round rack with vertical stainless steel tubes fitted in the high pressure vessel. A magnetic bar is placed in each stainless steel tube. A screen cylinder is installed inside the ring of stainless steel tubes. As the contaminated sulfolane is passed through the rejuvenator, the rejuvenator picks up its contaminants. The rejuvenator can be dissembled to remove the contaminants periodically. The rejuvenator is characterized by simple in construction, reliable in operation, and low in operation and maintenance costs. With this rejuvenator, the extraction system can be operated at high efficiency and high capacity without the dreaded corrosion.

    摘要: Aliphatic esters, R'COOR are produced by reacting the corresponding alcohol, ROH having carbon numbers of the alkyl groups, R′ and R, between 0 and 9 and 1 and 10, respectively, with molecular oxygen in the presence of a dual functional catalyst comprising metal on acidic solid support. In particular, the process is used advantageously for production of ethyl acetate by conversion of ethanol. The reaction mixture from the reactor is separated through azeotropic distillation to recover the ethyl acetate as product and the by-product, acetaldehyde and acetic acid which could be recycled for further reaction. The process is characterized by high conversion of ethanol, high selectivity and high yield for ethyl acetate and low waste stream generation. The preferred catalyst is Pd on zeolites which is active, selective, stable and regenerable.

    摘要: Acidic halides, especially chlorides, are removed from dry process vapor and liquid hydrocarbon streams by contact with solid caustic, such as a bed of NaOH. Salt deposits from form on the solid caustic, which are periodically removed by passing a liquid hydrocarbon continuous phase containing a minor amount of dissolved or entrained water over the solid caustic. Salts may be removed from the liquid hydrocarbon by extraction with water, which also saturates the liquid hydrocarbon so that it may be used to remove additional salt deposits.
