Abstract

Effect of mesoporous materials produced from commercial zeolite HBeta (MMZHBeta) on in-situ catalytic pyrolysis of Robinia pseudoacacia sawdust was investigated using a pyrolyzer gas chromatography/ mass spectrometry. Compared to non-catalytic pyrolysis, catalytic pyrolysis over MMZHBeta showed higher selectivity for furan and light olefin formation due to the weak acidity of MMZHBeta. The catalytic activity of MMZHBeta was improved by increasing acidity (from Si/Al 300 to 25) and catalyst to sample ratio (from 1:1 to 3:1). At the higher catalyst to sample ratio, the conversion of phenolics into aromatics and coke was maximized. This indicates that MMZHBeta can supply enough pore size for the large molecules to diffuse into the pores of the catalyst and the reaction efficiency can be increased by the increase of acid sites of the catalyst.
