研究了铁氧化物复合催化剂（ZrO 2-Al 2 O3-FeOx）将植物生物质中的芳香族化合物转化为有用芳香族化合物的催化活性。研究了木质素组分相关的二苯醚、二苯甲烷、2-苄氧基苯酚等二元芳烃和愈创木酚、苯乙酮、1-苯基-1-丙醇等单元芳烃在ZrO 2-Al 2 O3-FeOx催化剂上的催化裂解反应。催化反应在固定床反应器中于773 K和常压下进行。在ZrO 2-Al 2 O3-FeOx催化剂上，二苯醚和二苯甲烷是稳定的，而2-苄氧基苯酚是热分解的，随后生成甲苯和苯酚。愈创木酚和苯乙酮分别被选择性地转化为54 C-mol%的苯酚和29 C-mol%的苯。甲氧基和羰基分解成主要由CO2组成的气体产物，而1-苯基-1-丙醇中的脂肪族羟基的脱水主要发生以产生1-苯基-1-丙烯。ZrO 2-Al 2 O3-FeOx催化剂可有效降解芳环之间的烷基醚键，以及环上取代的甲氧基和羰基。
The catalytic activity of iron oxide composite catalyst (ZrO2–Al2O3–FeOx) was investigated for converting aromatic compounds derived from plant biomass into useful aromatics. Catalytic cracking of lignin constituent-related di-aromatics such as diphenyl ether, diphenyl methane, and 2-benzyloxyphenol, and mono-aromatics such as guaiacol, acetophenone, and 1-phenyl-1-propanol was carried out over ZrO2–Al2O3–FeOx. The catalytic reactions were conducted in a fixed-bed reactor at 773 K under atmospheric pressure. Diphenyl ether and diphenyl methane were stable, whereas 2-benzyloxyphenol was thermally decomposed, followed by the production of toluene and phenol over ZrO2–Al2O3–FeOx. Guaiacol and acetophenone were selectively converted into 54 C-mol% of phenol and 29 C-mol% of benzene, respectively. The methoxy and carbonyl groups were decomposed into gaseous products mainly consisting of CO2, whereas dehydration of the aliphatic hydroxyl group in 1-phenyl-1-propanol mainly occurred to produce 1-phenyl-1-propene. ZrO2–Al2O3–FeOx catalyst is effective for degrading alkyl ether bonds between aromatic rings, and the ring substituent methoxy and carbonyl groups.
