Abstract
An alkylation process which utilizes a solid alkylation catalyst is disclosed. The catalyst, which has carbonaceous material adsorbed thereto, is regenerated by reacting the adsorbed carbonaceous material. The reaction step is accomplished by heating the catalyst in the presence of ozone to form an ozonated hydrocarbon, wherein the ozonated hydrocarbon includes carbonyl carbons. The ozonated hydrocarbon is removed by desorbing the carbonyl carbons from the solid alkylation catalyst. The carbonaceous material is preferably reacted at a temperature ranging from about 20.degree. C. to 200.degree. C. The ozone is preferably in a gaseous stream at a concentration ranging from about 1 to 50 volume percent. The carbonyl components are preferably desorbed from the heated alkylation catalyst by sweeping the catalyst with a desorption fluid.
