摘要:
采用同步热分析仪对金属氧化物(ZnO,MgO和TiO2)和生物质的混合物分别在N2气氛和Ar气氛中进行了实验研究,发现3种样品的热分析曲线虽略有不同,但反应机理基本一致,可以分为生物质的热解反应和金属氧化物的热还原反应两部分。同时结果表明,采用生物质直接作为碳质原料来还原金属氧化物是可行的; ZnO/生物质混合物在1 100 ℃左右基本能完全反应,为太阳能高温热化学转化的一个方向。
Abstract:
The mixture of metal oxides(ZnO,MgO and TiO2)and biomass were investigated using TG/DSC simultaneous thermal analyzer in N2 atmosphere and Ar atmosphere respectively. It was found that the thermal analysis curves of the three samples were slightly different,but the reaction mechanism was basically the same,which could be divided into two steps:the pyrolysis of biomass and the thermal reduction of metal oxides. At the same time, the results show that it is feasible to reduce the metal oxide by using biomass directly as carbon material,and the ZnO/ biomass mixture can completely react at about 1 100 ℃,which is a direction for the solar thermochemical conversion.
