Direct Aerosol Synthesis of Large-Pore Amorphous Mesostructured Aluminosilicates with Superior Acid-Catalytic Properties

摘要

Making the best use of the petroleum resources still available is a necessity while alternative energy technologies mature. Thus, the conversion of heavy petroleum fractions into fuel is an important technological and economical challenge, especially to meet the needs for fuels. New refining catalysts are required, as the structured aluminosilicates commonly used are not optimum. The narrow pore size of zeolites is a limitation for the diffusion of heavy molecules, whereas the amorphous nature of mesostructured aluminosilicates reduces their potential activity (as a result of their moderate acidity) and hydrothermal resistance.
