Synthesis and Characterization ZSM-5 Based on Kaolin as a Catalyst for Catalytic Cracking of Heavy Distillate

Abstract

This article describes the study of synthesis of ZSM-5 Zeolite based on kaolin as catalysts for catalytic cracking of heavy distillate. There are five types of formulas A, B, C, D, and E synthesized with varying the molar ratios of SiO2/Al2O3, SiO2/Na2O, and H2O/SiO2 and characterized by chemical compound, microstructure and catalytic performance. Three methods conducted the catalytic cracking of heavy distillate such as without catalyst, Ni-Mo commercial catalyst, and bifunctional catalyst ZSM-5 from Formula E, which was impregnated with transition metals (Ni, Mo) to be Ni-Mo/HZSM-5. The catalytical performance test result shows that, under operational conditions (~350 °C, 1 MPa), middle distillate hydrocarbon is obtained by the catalytic cracking of heavy distillate using Ni-Mo commercial catalyst and Ni-Mo/HZSM-5 Formula E catalyst. When a Ni-Mo/HZSM-5 Formula E catalyst and Ni-Mo Commercial Catalyst were used in the cracking process, a light hydrocarbon fraction (C3 - C5) was formed.
