Abstract
Mesoporous hexagonal, cubic or wormhole aluminosilicates derived from zeolite seeds using an ionic structure directing agent are described. The aluminum in the structures is stable so that the framework of the structures does not collapse when heated in the presence of water or water vapor (steam). The steam stable aluminosilicates can be used as acid catalysts for hydrocarbon conversions, including the fluidized bed catalytic cracking and the hydrocracking of petroleum oils, and other cracking of organic compounds.
