Abstract
Methods are provided for effecting the acid catalyzed transfer of alkyl substituents from a first benzenoid specie to a second benzenoid specie at an improved rate. According to a preferred embodiment, the first and second benzenoid species are blended together with an effective amount of acid catalyst. An amount effective to improve the rate of transalkylation of at least one polynuclear aromatic hydrocarbon is then added to the blend which is maintained at a temperature above room temperature for a period of time sufficient to allow a substantial degree of transalkylation to occur. According to another preferred embodiment, a mixture of benzenoid species such as is found in a fuel or a chemical feedstock is improved through the acid catalyzed transalkylization reaction enhanced by the addition of a polynuclear aromatic hydrocarbon.
