“…Another type of solid acid catalysts has been in the spotlight of academic research as a promising candidate for heterogeneous alkylation. − Sulfated form of metals/mixed metals (SO 4 2– M x O y ) are considered as a low-cost, eco-friendly, and non-corrosive catalysts. Furthermore, they possess superior stability, displaying high efficiency toward catalytic performance.…”

“…The more moderate activity of SA has been attributed to lower acid site strength, as determined by Hammett acidity functions ( H 0 ). Furthermore, sulfated zirconium and tin dioxides are thought to have large Hammett acidity functions H 0 in comparison to other sulfated oxides . The catalytic activity of SZ was affected by both sulfur loading level and surface crystal phase, as the grafting rate and distribution of sulfur have a strong relationship with the transformation of mesopores to micropores due to pore blocking of sulfur ions.…”

Although research in renewables is growing at a tremendous rate, the world will still be greatly dependent on fossil fuels for at least the first half of this century. In the quest for more efficient and clean fuels, oil refining companies have turned their attention to processes such as reforming and alkylation technologies; in the latter process, isobutane is reacted with butenes and/or propylenes to produce, among others, branched isooctane, which is the main high-octane component of the gasoline pool. The main benefit of this process is the possibility to produce sulfur-free high-octane fuels, so important economic and environmental advantages are foreseen if investments in this area are realized. This Review analyzes and discusses the most recent progress on catalyst technologies, starting from the traditional sulfuric acid process and proceeding to newly emerging catalyst technologies such as solid acid and ionic liquid-based catalysts. We start with basic mechanistic analyses and conclude this Review with the new nonliquid acid-based commercial and emerging technologies for isobutane alkylation. Emphasis is given to the structure−activity relationships and the advantages and disadvantages present in every discussed catalyst material.
