摘要

通过管式炉热裂解实验装置考察了氧化物、复合氧化物、盐和负载型Na2CO3作为催化剂对甘蔗渣热裂解产物（二氢苯并呋喃和苯）选择性的影响。结果表明，氧化物、复合氧化物和盐催化剂对高附加值的2，3-二氢苯并呋喃有非常好的选择性，在复合氧化物上产率可达14.15%；而Na2CO3负载型热裂解催化剂对苯的选择性较高，其中，在Na2CO3/TiO2催化剂上产率可达到22.42%。

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.
