摘要： A process for the alkylation of at least one isoparaffin by at least one olefin in the presence of at least one solid acidic catalyst, characterized in that the major portion of the olefin is initially brought into contact with the catalyst in a complexing zone to form an olefin-catalyst complex in the presence of the isoparaffin, and in that the suspension of the complex in the isoparaffin is then sent to at least one alkylation reaction zone.

摘要： The process of butene-1 production comprises the steps of: a) sending a inhibited catalyst containing reactor effluent to a flash section where the pressure is decreased by about 0.1 MPa to about 2 MPa, and obtaining a first gaseous phase containing ethylene and butene-1 and a first liquid phase containing the inhibited catalyst; b) sending the first liquid phase from step a) to at least one vaporisation section which allows the separation of a second gaseous phase containing butene-1 and ethylene from a second liquid phase containing the inhibited catalyst; c) sending the second liquid phase from step b) to at least one thin film evaporation section which allows the separation of a third gaseous phase containing ethylene, butene-1 and some other heavier hydrocarbon products from a concentrated inactivated catalyst solution and, d) collecting the first, second and third gaseous phases to form a gaseous reactor effluent substantially free of spent catalyst.

摘要： Manufacture of catalysts containing at least four essential metals: copper, zinc, aluminum and at least one metal selected from the group formed of rare earths and zirconium.The process comprises the formation of a crystallized precipitate of the above-mentioned metals by intimate mixture of a crystallized precipitate of copper, zinc and aluminum, containing less than 0.06% by weight of sodium after washing, with a precipitate of at least one metal of the rare earths group and/or zirconium, containing less than 3% of nitrogen after washing.The catalysts are used in balanced reactions involving alcohols and synthesis gases, and particularly for methanol synthesis.
