摘要： Process for the liquid phase alkylation of a process stream of a hydrocarbon substrate and an olefinic alkylating agent in presence of an acid catalyst comprising one or more fluorinated sulphonic acids in at least a first alkylation stage and at least a second alkylation stage connected in series, each reaction stage being carried out in at least a first reactor containing a fixed bed of particulate polar contact material, which process comprises steps of:

(a) establishing a reaction zone on the polar contact material arranged in a first reactor of each process stage, the alkylation catalyst being moveable adsorbed on a confined area of the contact material in the reactor;
(b) passing a stream of the hydrocarbon substrate and a first stream of the alkylating agent at alkylating conditions in a first flow direction through the first alkylation stage and withdrawing an effluent stream containing alkylated product and unconverted hydrocarbon substrate from the first alkylation stage;
(c) adding a second stream of the alkylating agent to the effluent stream from the first alkylation stage and passing the mixed stream at alkylating conditions in a first flow direction through the second alkylation stage, and
(d) withdrawing a product stream of alkylated product from the second alkylation stage.

摘要： Process for the recovery of spent fluorinated sulphonic catalyst from acid soluble oil (ASO) being formed during alkylation of hydrocarbons in presence of the acid catalyst, comprising steps of
   washing the ASO with water and recovering an aqueous solution of the acid catalyst,
   neutralizing the acid in the aqueous solution by adding to the solution a basic compound being selected from the group of amino compounds, ammonia and ammonium salts, thereby, forming ammonium salts of the acid catalyst with a melting point at which the obtained acid catalyst salt in a subsequent concentration and drying step is in the form of a melt,
   drying the melt, and finally
   recovering the acid catalyst by protonisation of the dried melt with sulphuric acid and distilling off the recovered acid catalyst from the sulphuric acid.
