A method and apparatus for the continuous overbasing of petroleum sulfonate providing in a process in which CO.sub.2 is contacted with a reaction mixture of neutral petroleum sulfonate, lube oil stock, lime, methanol, and naphtha in a series of reaction vessels in which additional CO.sub.2 is contacted seriatim in each succeeding reaction vessel with the effluent from the preceding reaction vessel, a method and apparatus for the removal of at least a portion of the effluent from each reaction vessel with the reduction of water content in this portion and subsequent supplementing of methanol content in this portion to provide a reaction efficient amount of water and methanol in each succeeding reaction.

In a process for isomerizing light hydrocarbons with a catalyst system comprising a halogenated alumina or platinum alumina when hydrogen is utilized to sustain the catalyst activity, the ratio of hydrogen to hydrocarbon in the feed is decreased and the temperature increased after a substantial period of operation. This results in an improved conversion and selectivity which allows for increasing the total catalyst life.
