Hydrogen fluoride alkylation with apparatus having a venturi-shaped chamber
Abstract
Abstract AN ALKYLATABLE REACTANT IS ALKYLATED WITH AN OLEFINACTING REACTANT, UTILIZING A FLUID CATALYST, BY PASSING THE REACTANTS AND CATALYST THROUGH A VENTURI-SHAPED ZONE AND A RETENTION ZONE INTO A SEPARATION ZONE. A CATALYST PHASE AND A REACTION PRODUCTS PHASE ARE SEPARATED AND THE CATALYST PHASE IS WITHDRAWN. A FIRST PORTION OF THE REACTION PRODUCTS PHASE IS WITHDRAWN AND A SECOND PORTION IS PASSED THROUGH A REFLUXING ZONE. THE PORTION OF REACTION PRODUCTS PHASE WITHDRAWN FROM THE SEPARATION ZONE IS RECYLED TO THE VENTURI-SHAPED ZONE. CATALYST IS INTRODUCED INTO THE DOWNSTREAM END OF THE REFLUXING ZONE AND PASSED COUNTER-CURRENTLY TO THE SECOND PORTION OF REACTION PRODUCTS. THE SECOND PORTION OF THE REACTION PRODUCTS IS WITHDRAWN AND THE PRODUCT OF THE PROCESS IS RECOVERED FROM IT. ALSO DISCLOSED IS A NOVEL UNITARY ALKYLATION APPARATUS COMPRISING, IN COMBINATION, A VENTURI-SHAPED CHAMBER, A RETENTION CHAMBER, A SETTLING CHAMBER AND A REFLUXING CHAMBER.
