Synthesis of HKUST-1 and zeolite beta composites for deep desulfurization of model gasoline.

Composites of zeolite beta microspheres@nanosized HKUST-1 and micro-octahedron-shaped HKUST-1@nanosized zeolite beta were fabricated to remove thiophene from model oil. The two composite materials exhibited a higher adsorption capacity and faster adsorption rate than their corresponding mechanical mixture of HKUST-1 and zeolite beta when the sulfur concentration was at around 100 ppmw.
