Abstract: The present invention relates to a hydrocracking catalyst based on hierarchically porous beta-zeolite, a method of preparing the same, and a method of producing bio-jet fuel from triglyceride-containing biomass by use of the hydrocracking catalyst, and includes methods comprising preparing a hydrocracking catalyst by supporting a metallic active component on a hierarchically porous beta-zeolite support, and converting n-paraffins, produced from triglyceride-containing biomass, into bio-jet fuel by hydrocracking in the presence of the prepared hydrocracking catalyst. When the hydrocracking catalyst based on hierarchically porous beta-zeolite is used, the residence time of the reactant and the product in the zeolite crystals may be reduced due to additional mesopores formed in the zeolite, and thus bio-jet fuel may be produced in high yield from n-paraffin feedstock produced from triglyceride-containing biomass.

Abstract: The present disclosure relates to a method for preparing a multi-level pore zeolite, including: (A) a step of mixing a silicon precursor, an aluminum precursor, a phosphorus precursor, a structure directing agent and water; a step of (B) adding phenylphosphonic acid, carbon black or a mixture thereof to the mixture prepared in the step (A) and mixing the same; a step of (C) crystallizing the mixture prepared in the step (B) by heat-treating the same; and a step of (D) calcining the crystallization product, and utilization of the prepared multi-level pore zeolite as a catalyst for hydroisomerization of normal paraffins. The catalyst exhibits improved isoparaffin yield when it is used as a catalyst for hydroisomerization of normal paraffins such as diesel or lube base oil by supporting an active metal component because residence time of reactants and products in the zeolite crystals are decreased due to mesopores and the proportion of external acid sites to total acid sites is low.
