以餐厨废油模型化合物为原料制备活性炭(AC),并负载金属Ni、Cu组分制备系列催化剂,用于催化裂解餐厨废油模型化合物(MWCO)制取氢气和碳纳米管(CNTs)。通过ICP-OES、N₂-BET、XRD、H₂-TPR对催化剂进行结构和化学表征。研究了不同Ni和Cu质量分数催化剂、裂解温度、废油流量对产氢量的影响。结果表明,20% Ni-10% Cu/AC为催化剂时,反应活性最高,850℃时氢气瞬时体积分数可达41.1%,得到的CNTs产率最高为1 528%。CNTs主要为丝状多壁结构,且具有较高的氧化稳定性和石墨化程度。

Activated carbon (AC) is prepared from model waste cooking oil compounds,and a series of catalysts are prepared by loading metal Ni and Cu components on the prepared AC,which are used to catalyze the decomposition of model waste cooking oil compounds (MWCO) to produce hydrogen and carbon nanotubes (CNTs).The structural and chemical characterization of the catalyst are carried out by means of ICP-OES,N₂-BET,XRD,H₂-TPR.The effects of the catalysts with different Ni and Cu contents,cracking temperature and waste cooking oil flow rate on hydrogen production are studied.It is indicated that the reaction activity reaches the highest when 20%Ni-10%Cu/AC is used as the catalyst,over which the instantaneous volume fraction of hydrogen can reach 41.1% at 850℃,and the yield of CNTs is up to 1 528%.CNTs obtained have filamentous multi-walled structure,and show a high oxidation stability and a high degree of graphitization.
