本文以柳按生物质为原料,通过热裂解手段制得生物油及其副产物生物炭。通过化学活化对生物炭的表面性质进行改善。采用扫描电镜进行表征,研究表明活化炭经处理后的表面出现了大量孔隙结构。采用氮气物理吸附检测表明活化炭的孔结构主要集中在10 nm以下,4 nm附近。将活性金属Ni负载于活化后的生物炭上制得重整催化剂,并在生物油模化物重整制氢中表现出了良好的反应活性。尤其在高温段,在700℃时氢气产率接近100%。

In this paper, willow according to biomass as raw material, by means of pyrolysis obtained bio-oil and its by-product biochar. The surface properties of biochar are improved by chemical activation. Characterization by scanning electron microscopy showed that a large amount of pore structure appeared on the activated carbon surface. The results of nitrogen physical adsorption showed that the pore structure of activated carbon mainly concentrated below 10 nm and around 4 nm. The active metal Ni is supported on the activated biochar to obtain a reforming catalyst, and exhibits good reactivity in the reforming of bio-oil-based products. Especially at high temperature, the hydrogen yield is close to 100% at 700 ° C.
