Abstract
Paraffins and other hydrocarbons are alkylated using a solid bed catalyst in a process featuring a reaction zone operated at mixed-phase conditions which allow the heat of reaction to vaporize a portion of the liquid phase feed hydrocarbon passing downward through it thus facilitating recycling of the feed hydrocarbon. The feed hydrocarbon recovered from the reaction zone effluent is recycled as a liquid, preferably admixed with hydrogen, with the feed olefin being preferably introduced near the top of the reactor as a vapor. The catalyst preferably contains a metal hydrogenation function effective to selectively hydrogenate C.sub.6 -plus olefins produced as by-products.
