摘    要:以一种廉价的农林废弃物——松木粉为原料,首先经过炭化和活化处理,制备活性炭,再通过苯磺酸重氮盐还原法处理活性炭引入磺酸基团(—SO3H),从而制备出具有高比表面积的炭基固体酸催化剂(AC-SO3H)。其比表面积达到1364 m2/g,磺酸基密度为1.36 mmol/g。以乙酸的酯化反应考察了炭基固体酸催化剂的催化活性,并与Amberlyst-15、Nafion NR50以及Nafion SAC-13等几种固体酸催化剂进行了比较。实验结果表明,炭基固体酸催化剂的催化活性仅略低于Amberlyst-15,高于Nafion NR50和Nafion SAC-13,炭基固体酸催化剂的成本也远远低于Nafion NR50和NafionSAC-13。研究结果表明,以松木粉为原料,通过炭化、活化和磺化处理能够得到性能优异且成本低廉的炭基固体酸催化剂。

关 键 词:松木粉  高比表面  炭基固体酸  催化剂

Abstract:A sulfonated(SO3H-bearing) Carbon-based solid acid catalyst was prepared from pine wood powder — a cheap forest waste.The catalyst was obtained by the carbonization,activation and sulfonation of pine wood powder.The specific surface area and SO3H density of the carbon catalyst were 1364 m2/g and 1.36 mmol/g,respectively.The catalytic activity of carbon catalyst was investigated on the acetic acid esterification reaction and compared with that of several commercial solid acid catalysts,such as Amberlyst-15,Nafion NR50 and Nafion SAC-13.The results showed that the catalytic activity of carbon catalyst was lower than that of Amberlyst-15,but higher than that of Nafion NR50 and Nafion SAC-13.Its cost is much lower than that of Nafion NR50 and Nafion SAC-13.It also showed that carbon-based solid acid catalyst can be prepared by carbonization,activation and sulfonation of pine wood powder.
Keywords:pine wood powder  high specific surface area  carbon-based solid acid  catalyst
