The preparation, characterization and catalytic activity of a new solid acid catalyst system
The preparation and use of solid strong acid catalysts and superacids are active areas of research. Solid acids and superacids are reported to exhibit extremely high catalytic activities for reactions such as isomerization, cracking, hydrocracking, dehydration, alkyation, acylation, conversion of methanol to gasoline, and so forth. Recent research in this area has focused on the preparation of stronger solid acids and their characterization. Advantages of solid acid catalysts over liquid acid catalysts include ease of separation from reaction mixture and high selectivity or specific activity. A series of novel solid strong acids have been prepared by treatment or inorganic oxides by Lewis acids. The method of creating or enhancing the number of tetrahedral aluminum centers on inorganic oxides has led to a series of novel solid acid catalysts which display an increased acidity over the supports alone. Investigations of acid sites by the infrared spectroscopy of adsorbed pyridine, calorimetric titrations and solid-state nuclear magnetic resonance on a series of new solid acid catalysts are discussed. This new solid acid catalysts system exhibits high catalytic activity and selectivity for cracking reactions under relatively mild conditions. In addition to the reaction of hydrocarbons, the reaction of various polychlorinated molecules has been studied.
