生物质碳基固体酸的制备及其催化性能研究

Study on Preparation and catalytic properties of biomass carbon based solid acid system

以花生壳为原料,通过碳化-磺化一步法制备碳基固体酸,考察了制备条件对碳基固体酸表面酸密度的影响。并将所制备的碳基固体酸催化剂用于油酸和甲醇的酯化反应中,以油酸甲酯的产率为考察指标评价其催化性能,并对其重复使用性进行了研究。

Taking peanut shell as raw material,through one step method of preparing carbonized sulfonated carbon based solid acid,the effects of preparation conditions on the surface of carbon based solid acid acid density.The prepared carbon based solid acid catalyst was used in the esterification of oleic acid and methanol.The catalytic performance was evaluated with the yield of oleic acid methyl ester,and its repeated use was studied.
