Abstract:
Lignin is the only nature renewable resource which can provide large quantities of aromatic compounds. In the work, transformation of lignin into benzene, toluene, and xylenes (BTX) was investigated over the HZSM-5, HY, and MCM-22 catalysts, and the HZSM-5 catalyst showed the highest carbon yield of BTX. The reaction condition, including temperature, the gas flow rate, and the catalyst/lignin ratio, was also investigated. The carbon yield of BTX reached about 25.3 C-mol% over HZSM-5 catalyst under T=550 oC, f(N2)=300 cm3/min, and catalyst/lignin ratio of 2.

摘要:
对HZSM-5、HY和MCM-22三种催化剂进行了比较, 其中HZSM-5催化裂解木质素制备苯、甲苯和二甲苯(BTX)的结果最优.确定了木质素催化裂解的最佳反应条件,包括反应温度、载气流速、催化剂/木质素配比.当反应温度为550~600 oC,载气流速为300 mL/min,催化剂/木质素配比为2时,使用HZSM-5催化裂解制备BTX的最高C产率和芳香选择性分别可达25.3%和90.9%。
