| Abstract: | The influence of different pyrolysis catalysts (oxide, composite oxide, salts and supported Na2CO3) for bagasse on product (2, 3-dihydrobenzofuran and benzene) yield was investigated by pyrolysis experiment. Oxide, composite oxide and salt catalysts had high selectivity for high value 2, 3-dihydrobenzofuran (2, 3-DHB), with the highest yield (14.15%) over composite oxide. Supported Na2CO3 catalysts had high selectivity for benzene and the yield was as high as 22.4% over Na2CO3/TiO2. |
