    摘要: Process for the recovery of fluorinated sulphonic acid catalyst from tar being formed during alkylation of hydrocarbons in the presence of the fluorinated sulphonic acid catalyst and containing spent fluorinated sulphonic acid catalyst in form of salts with basic components in the tar, which process comprises,
       treating the tar with a proton donating acid by mixing of the acid and the tar, thereby, converting the spent catalyst to the fluorinated sulphonic acid;
       separating the obtained fluorinated sulphonic acid from the tar-acid mixture by stripping off the acid from the mixture with an inert stripping agent at a temperature of 0-200 o C and pressure of 0.001-1 atm; and finally
       recovering the separated fluorinated sulphonic acid from the stripping agent.

    摘要: There is disclosed an improved process for the production of linear alkylbenzene wherein monoolefins are reacted with benzene in a hydrogen fluoride catalyzed reaction followed by recovery of the alkylbenzene. An alumina treatment step is included which removes organic fluoride impurities in order to prevent release of hydrofluoric acid in downstream equipment. It has been discovered that the SO₃ sulfonation color of the alkylbenzene is surprisingly improved by the use of a high selectivity basic alumina for this treatment.

    摘要: Improved process for the acid-catalyzed conversion of a reactant into a reaction product wherein the improvement comprises contacting said reactant with an acid catalyst represented by general formula (I), wherein X is selected from the group consisting of oxygen, sulfur or represents 2 hydrogen atoms; Z is selected from the group consisting of the anions of strong acids, e.g. chloride, bromide, bisulfate, nitrate or dihydrogen phosphate; R1 is hydrogen or a lower alkyl having one to four carbon atoms; R is hydrogen or a methyl radical; m is an integer of from 2 to 6; n is 0 or 1; and o is 0 or an integer of from 1 to 17, at reaction conditions, and recovering a reaction product. Reactants which may be converted into reaction products in the process of this invention include hydrocarbons and heteroatom-substituted hydrocarbons, wherein said heteroatoms may be selected from the group consisting of nitrogen, oxygen, sulfur, phosphorus and halogen atoms. For example, in the present inventive process, olefins may be reacted with tertiary alkanes to provide alkylated products; olefins may be reacted with carboxylic acids to obtain esters; alcohols may be dehydrated to obtain olefins or ethers or reacted with carboxylic acid to obtain an alkylated product or an ester, respectively; anhydrides may be reacted with an aromatic or an olefinic compound to obtain acetylated derivatives thereof; epoxides may be reacted to the corresponding glycols, etc.

    摘要: An acid alkylation process is controlled so as to maintain a desired ratio of isobutane to olefins in a fluid stream flowing to the alkylation reactor and to maintain a desired acid to hydrocarbon ratio in the alkylation reactor. Also, if parallel alkylation reactors are utilized, the flow rate of the olefin stream to one of the alkylation reactors is manipulated so as to maintain a balanced loading on the parallel alkylation reactors. Such control results in improved quality of the alkylate produced and also improves the amount of alkylate produced from a particular amount of fluid to the alkylation reactor.
