Abstract

Cesium-modified amorphous silica alumina (Cs/ASA) is a promising catalyst for the production of hydrocarbons through pyrolysis of biomass. Catalytic pyrolysis of pinewood over Cs/ASA in a pyrolyzer system in conjunction with a gas chromatograph and mass spectrometer resulted in a 22% yield of hydrocarbons containing more than 50% aliphatic hydrocarbons. Factors such as the nature of the support and the concentration of Cs+ ions influenced the catalyst activity for the production of hydrocarbons. Physicochemical characterization showed that the cesium exists in the form of Cs2CO3, which interacts strongly with the ASA support.
