Abstract
A method for hydrocracking a hydrocarbon feedstock, the method comprising: contacting the hydrocarbon feedstock with a catalyst containing a nano-sized mesoporous zeolite composition under reaction conditions to produce a product stream containing at least 20 weight percent of hydrocarbons with 1-4 carbon atoms, wherein the nano-sized mesoporous zeolite composition is produced by a method that includes: mixing silica, a source of aluminum, and tetraethylammonium hydroxide to form an aluminosilicate fluid gel; drying the aluminosilicate fluid gel to form a dried gel mixture; subjecting the dried gel mixture to hydrothermal treatment to produce a zeolite precursor; adding cetyltrimethylammonium bromide (CTAB) to the zeolite precursor to form a templated mixture; subjecting the templated mixture to hydrothermal treatment to prepare a CTAB-templated zeolite; washing the CTAB-templated zeolite with distilled water; separating the CTAB-templated zeolite by centrifugation; and drying and calcining the CTAB-templated zeolites to produce a nano-sized mesoporous zeolite composition.
