Abstract

1491593 Alkylating isoparaffins using HF catalyst STRATFORD ENG CORP 4 March 1975 [4 March 1974] 8995/75 Heading C5E An isoparaffin is alkylated with an olefin in the presence of HF catalyst by passing the reaction mixture sequentially through a reaction zone, a settling zone and a cooling zone, withdrawing from the settling zone at least a portion of a hydrocarbon layer formed therein, reducing the pressure on the withdrawn hydrocarbon, thereby to reduce the temperature, controlling the reaction temperature by indirect heat exchange in the cooling zone with the temperature-reduced portion as coolant and recovering alkylate from the coolant. The reaction zone is preferably in a vertical tubular reactor which communicates directly at opposite ends with an overhead settler and a cooler underneath, there being in addition a recycle line from cooler to settler. A portion of the coolant may be used to cool the reactants prior to the reaction. On pressure reduction, the withdrawn hydrocarbon yields a vapour-liquid mixture which is used as coolant and may then be subsequently separated into a liquid and a vapour phase. Each of these may be recycled to the reaction, optionally after removal of isobutane and propane respectively. HF may be recovered from the vapour phase and recycled to the reaction step. The process is particularly applicable to the alkylation of isobutane with C 3 -C 5 olefins.
