摘　　要：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%。Bio-oil and the byproduct biochar were produced from fast pvrolysis with lauan biomass as raw material.The surface property of lauanbiochar was enhanced by activation pretreatment.A lot of pore structure was observed in the activated biochar surface in the SEM pictures.The pore structure mainly centered below 10 mn and around 4 nm according to N_2 physical adsorption.After loading the active metal Ni,the developed catalyst displayed fine reaction activity.Especially at high temperature,the hydrogen yield achieved almost 100%at 700℃.
