研究了木质素两步转化制酚的新工艺。在第一步中，在高压釜反应器中使用二氧化硅-氧化铝催化剂在水/1-丁醇溶液中进行木质素的解聚。在适宜的反应条件下，木质素衍生物液体产物的产率可达85- 88 C-mol %。在第二步中，使用固定床流动反应器在氧化铁催化剂上进行来自第一步的液体产物的催化裂化。酚类总回收率为6.6-8.6%，甲氧基酚转化率为92- 94%。
Production of phenols from lignin was investigated using a new conversion process consisting of two reaction steps. In the first step, depolymerization of lignin was carried out in an autoclave reactor using a silica-alumina catalyst in a water/1-butanol solution. The yield of lignin-derived liquid product reached 85–88C-mol% under the appropriate reaction conditions. In the second step, catalytic cracking of the liquid products from the first step was carried out using a fixed‐bed flow reactor over an iron oxide catalyst. With this method, total recovered fraction of phenols and the conversion of methoxy phenol reached 6.6–8.6% and 92–94%, respectively.
