Role of zeolite catalysts for benzene removal from gasoline via alkylation: A review

The allcylation of benzene into both mono- and multi-allcylated benzenes is a forefront technology recently considered by the petroleum refineries for the reduction of benzene from gasoline feedstock. Its advantages over the other reduction technologies include retention of octane properties and limiting the consumption of hydrogen. The technology is therefore widely considered at the global scale. The choice of most appropriate catalyst and reaction conditions is very important. Catalyst suitable for this reaction must be highly active, regenerable, selective and resistance to deactivation by coking or poisons. The paper therefore surveyed classified literature on the role of zeolite catalysts for the allcylation reaction. It covered concise details on the effect of some vital parameters such as zeolite structure/porosity properties, Bronsted/Lewis acidity ratio and reaction conditions. (C) 2015 Elsevier Inc.
