Abstract: A method for making nano-sized mesoporous zeolite Beta may include calcining a precursor nano-sized zeolite Beta to form a calcined nano-sized mesoporous zeolite Beta intermediate material. The calcining may be at a temperature of from 400° C. to 650° C. The method may further include contacting the calcined nano-sized mesoporous zeolite Beta intermediate material with an acid to form the nano-sized mesoporous zeolite Beta.

Abstract: Described herein are nano-sized mesoporous zeolite Beta that may be made by a method that includes producing a precursor nano-sized zeolite Beta by a process including hydrothermally treating a mixture including a templating agent, a silica source material, an alumina source material, and water. The method may further include calcining the nano-sized zeolite Beta precursor to form a calcined nano-sized mesoporous zeolite Beta intermediate, wherein the calcining may be at a temperature of from 400° C. to 650° C. The calcining may remove framework aluminum from the nano-sized zeolite Beta precursor. The calcined nano-sized mesoporous zeolite Beta intermediate may have a lesser relative crystallinity than the nano-sized zeolite Beta precursor. The method may further include mixing the calcined nano-sized mesoporous zeolite Beta intermediate with water, and hydrothermally treating the calcined nano-sized mesoporous zeolite Beta intermediate to from the nano-sized mesoporous zeolite Beta.

Abstract: A method of catalytic hydrocracking. The method includes flowing a hydrocarbon feed comprising a heavy oil into a hydrocracking unit; and hydrocracking the hydrocarbon feed in the hydrocracking unit using a composite catalyst. The composite catalyst includes an ordered amorphous silica-alumina (OASA) having mesopores, a zeolite component having micropores, a first metal component, a second metal component, and a support material, where at least a fraction of the heavy oil is converted within the mesopores into an intermediate, and at least a fraction of the intermediate is further converted within the micropores to form a product stream including a middle distillate fraction.

Abstract: A method for making nano-sized mesoporous zeolite Beta may include heating, in an environment including 99 mol. % or greater inert gas, a precursor nano-sized zeolite Beta to form an inert gas-treated nano-sized mesoporous zeolite Beta intermediate material. The inert gas may be chosen from nitrogen, helium, argon, or combinations thereof. The method may further include heating, in an environment including 10 mol. % or greater oxygen gas, the inert gas-treated nano-sized mesoporous zeolite Beta intermediate material to form the nano-sized mesoporous zeolite Beta.

Abstract: A catalyst comprising a zeolite beta and a hierarchical zeolite Y. The zeolite beta comprises a plurality of micropores having a pore size of less than 2 nm and a plurality of mesopores having a pores size of greater than or equal to 2 nm to less than or equal to 50 nm. A volume of mesopores is greater than or equal to 35% of a total pore volume of the zeolite beta and an average particle size of the zeolite beta is less than or equal to 100 nm.
