    摘要: A process for the production of olefin sulfonates is presented. The process comprising generating olefins from normal alkanes through a dehydrogenation unit to produce a mixture of alkanes and alkenes. The mixture is sulfonated to react the olefins and generate olefin sulfonates. The olefin sulfonates are separated from the normal alkanes to produce a product stream, with the normal alkanes recycled to the dehydrogenation unit.

    摘要: A process is disclosed wherein a layered catalyst is used for the alkylation of benzene with a substantially linear olefin. The layered catalyst allows for shifting the operating conditions to increase the alkylation of benzene, while reducing the amount of isomerization of the alkyl group. This is important for increasing the quality of the alkylbenzene by increasing the linearity of the alkylbenzene.

    摘要: Integrated, energy efficient process for making detergent range alkylbenzenes, heavies coproduced during the alkylation of benzene with olefin using a solid, acidic catalyst are transalkylated. Spent benzene from regeneration of the solid, acidic catalyst used for alkylation provides at least about 50 percent of the benzene provided for the transalkylation. The integrated processes thus reduce the load on the benzene distillation assembly used in the alkylbenzene refining system.

    摘要: Spent benzene from a regeneration of a catalyst or solid sorbent in an alkylbenzene complex is subjected to a rough distillation and the benzene fraction from the rough distillation is used a at least a portion of the benzene for a unit operation in the alkylbenzene complex or is passed to a benzene distillation column in the crude alkylbenzene refining section. The processes of this invention can enhance the purity of the alkylbenzene product and can reduce energy consumption per unit of alkylbenzene product or can assist in debottlenecking the crude alkylbenzene refining section of the alkylbenzene complex.

    摘要: Dialkylbenzenes are transalkylated in the presence of benzene and solid catalyst. The transalkylation product is subjected to distillation to provide a lower-boiling, benzene-containing fraction which is fed to a transalkylation reactor as at least a portion of the benzene. Thus, high benzene to dialkylbenzene molar ratios can be economically maintained in order to enhance catalyst stability.

    摘要: Continuous processes for monoalkylating aromatic compound with an aliphatic feedstock comprising aliphatic olefin of 8 to 18 carbon atoms per molecule are effected using at least 3 reaction zones in series, each containing solid alkylation catalyst with effluent cooling between reaction zones, each of which reaction zones is supplied a portion of the fresh aliphatic feedstock, such that the Reaction Zone Delta T in each reaction zone is less than about 15° C. The overall aromatic compound to olefin molar ratio is less than about 20:1. The alkylation product has desirable linearity and low amounts of dimers, dealkylated compounds and diaryl compounds even though a low aromatic compound to olefin molar ratio is used.
