Abstract: HL/HW composite zeolite synthesized by a one-pot procedure showed good physicochemical properties in surface acid amount, acid type, and the characteristic of higher mesoporous proportion. HL/HW was used as the active additive component of a catalytic cracking catalyst and made a significant improvement in the catalyst performance.
