A method for reactivating a solid alkylation catalyst, which can be performed within a reactor that contains the alkylation catalyst, has been developed by INL researchers. Features of the fluid-reactivating agent used in this invention are that it can react with the fouling agents and dissolve some fouling agents. Also, the fluid-reactivating agent can be chosen to be one of the alkylation reactants and the fluid-reactivating agent can be optionally recovered and recycled after catalyst regeneration. The reactivating solid catalyst innovation has several advantages, some of which are that it permits faster and more complete catalyst reactivation, enhances the versatility of the methods of the current inventions, diminishes the duration and complexity of catalyst reactivation and permits the deactivated catalysts from not having to be immediately disposed of.
