Abstract:
A method for catalytic cracking or hydrocracking of an organic molecule into lower molecular weight components, which comprises:(a) providing in a reactor a catalytic cracking catalyst which comprises: a mesoporous aluminosilicate-carbon composition which comprises: a framework of tetrahedral linked SiO4 and AlO4 units, the framework defining mesopores having an Si to Al molar ratio of between about 1000 to 1 and 1 to 1 and between 0.01 and 10 wt % carbon embedded in the mesopores, and having at least one X-ray diffraction peak corresponding to a basal spacing between about 3.0 and 15.0 nm, wherein the tetrahedral AlO4 units in the framework exhibit a 27Al MAS-NMR resonance with a chemical shift between about 57 and 65 ppm relative to a 1.0 M aluminum nitrate solution as an external chemical shift reference, wherein a BET surface area is between 400 and 1300 m2 per gram, wherein an average pore size of the framework is between about 2.0 and 10.0 nm, and wherein a pore volume of the framework is between about 0.1 and 1.9 cm3 per gram; and a binder for the aluminosilicate-carbon composition; and (b) introducing the organic molecule onto the catalyst at temperatures and pressures which cause cracking of the organic molecule into the lower molecular weight components.
