Abstract

MCM-41-β-zeolite, a new type of molecular sieve with meso-microporous composite structure was synthesized hydrothermally by using cetyltrimethylammonium bromide and tetraethylammonium hydroxide as the template. The structure and property of the molecular sieve were studied by means of XRD, SEM, DTG, FTIR and probe reaction teachniques. The results show that the composite molecular sieve contains stable hexagonal mesoporous structure and the microporous structure of β-zeolite. It appears in globular particles with loose surface and the results of DTG and FTIR exhibit that the meso-microporous composite molecular sieve is different from the mechanical mixture of MCM-41 and β-zeolites. Compared with the mechanical mixture of MCM-41 and β-zeolites, MCM-41-β-zeolite has a much higher hydrocracking activity for n-heptane.
