Abstract: A process for converting crude oil to light olefins, aromatics, or both, includes contacting a crude oil with an FCC catalyst composition in a catalytic cracking system at a temperature of greater than or equal to 580° C., a weight ratio of the FCC catalyst to the crude oil of from 2:1 to 10:1, and a residence time of from 0.1 seconds to 60 seconds. Contacting causes at least a portion of hydrocarbons in the crude oil to undergo cracking reactions to produce a cracked effluent comprising at least olefins. The FCC catalyst composition for producing olefins and aromatics from crude oil includes ultrastable Y-type zeolite impregnated with lanthanum, ZSM-5 zeolite impregnated with phosphorous, an alumina binder, colloidal silica, and a matrix material comprising Kaolin clay.

In another embodiment, the present application pertains to a novel catalyst for methane dehydrogenation. The catalyst comprises amorphous particles of SiO2. The amorphous particles have a particle size with a nominal diameter of from about 5 nm to 1 cm. The amorphous particles of SiO2 comprise a Lewis acidity sufficient to activate one or more C—H bonds in methane and generate one or more methyl radicals when the catalyst is subjected to methane dehydrogenation conditions. In another embodiment, the present application pertains to method of making the novel catalyst for methane dehydrogenation.
