Abstract Pyrolysis of buckwheat straw with or without catalysts was investigated using the TGA-FTIR method to determine the influence of zinc-containing nanopowders (ZnO, 1.5 % Er2O3/ZnO, 2 % Ag/ZnO, ZnWO4, ZnAl2O4, and Mn-Zn ferrite) on the distribution of pyrolysis products. The presence of ZnWO4, ZnAl2O4, and Mn-Zn ferrite exhibited the highest bio-oil yields, whereas the highest non-condensable gas yield and the lowest bio-oil yield was obtained with the addition of 2 % Ag/ZnO catalyst. According to the obtained results, ZnWO4 promoted the production of oxygen-containing compounds while the presence of 2 % Ag/ZnO presented the highest amounts of hydrocarbons. The 2 % Ag/ZnO shows a greater effect on the production of monocyclic aromatic hydrocarbons but ZnWO4 inhibits the formation of these compounds. The amounts of olefins slightly increased in the presence of ZnWO4 while the ZnO significantly reduced the formation of olefins.

TGA-FTIR法含锌纳米粉对荞麦秸秆催化中间体热解的影响

摘要 使用 TGA-FTIR 方法研究了有或没有催化剂的荞麦秸秆热解，以确定含锌纳米粉末（ZnO、1.5% Er2O3/ZnO、2% Ag/ZnO、ZnWO4、ZnAl2O4 和 Mn-Zn 铁氧体）的影响。 ) 关于热解产物的分布。ZnWO4、ZnAl2O4 和 Mn-Zn 铁氧体的存在表现出最高的生物油产率，而添加 2% Ag/ZnO 催化剂的不凝气体产率最高，生物油产率最低。根据获得的结果，ZnWO4 促进了含氧化合物的产生，而 2% Ag/ZnO 的存在呈现出最高量的碳氢化合物。2% Ag/ZnO 对单环芳烃的产生有更大的影响，但 ZnWO4 会抑制这些化合物的形成。
