Sustainable production of aromatic-rich biofuel via catalytic co-pyrolysis of lignin and waste polyoxymethylene over commercial Al2<\/sub>O3<\/sub> catalyst<\/strong><\/p>\n

Recently, under the guidance of Associate Professor Lu-jiang Xu, master student Mr. Ge-liang Xie published an article on the preparation of high aromatic biofuels by lignin and waste polyoxymethylene (POM) catalytic co-pyrolysis in the journal Journal of Analytical and Applied Pyrolysis.<\/p>\n

Co-valorization of biomass and multiple solid wastes is essential to environment protection and energy security. Herein, aromatic-rich biofuel was produced from lignin and waste polyoxymethylene (POM) via catalytic co-pyrolysis process. Commercial and cheap \u03b3-Al2<\/sub>O3<\/sub> catalyst exhibited good catalytic performance. Series characterizations and bench-top pyrolysis experiments were conducted to illustrate the synergism between raw materials and the mechanism of aromatics formation. The TG analysis and thermodynamics calculation revealed that a remarkably positive synergistic effect existed between lignin and POM, could reduce the activation energies, and make the reaction more conducive in terms of thermodynamics. Meanwhile, the yields of biochar and bio-oil increased considerably Additionally, the operating conditions affected the product distributions significantly. The suitable mixing ratio of lignin to POM was around equal (5:5) with the bio-oil yield increased by 25% to 28.3% and aromatic hydrocarbons selectivity increased to >95%. Moreover, POM, the precursor for alkylating reagents and hydrogen donors, could promote the deoxygenation reactions of phenolic intermediates and result into aromatic hydrocarbons. The acid sites of \u03b3-Al2<\/sub>O3<\/sub> promoted series secondary cracking reactions (alkylation, deoxygenation), and thus improve bio-oil quality. Finally, the stability test showed that commercial \u03b3-Al2<\/sub>O3<\/sub> catalyst was slightly deactivated after 4 cycles because of coke deposits and acid sites loss.<\/p>\n

Using lignin and waste acetal (POM) as raw materials and commercial \u03b3-Al2<\/sub>O3<\/sub> as catalyst, aromatic-rich biofuels were prepared by catalytic co-pyrolysis process. The suitable mixing ratio of lignin and polyoxymethylene was about 5\u22365, the yield of bio-oil increased by 25% to 28.3%, and the selectivity of aromatic hydrocarbons increased to >95%.\u4ee5\u6728\u8d28\u7d20\u548c\u5e9f\u805a\u7532\u919b\uff08POM\uff09\u4e3a\u539f\u6599\uff0c\u5546\u4e1a\u03b3-Al2<\/sub>O3<\/sub>\u4f5c\u4e3a\u50ac\u5316\u5242\uff0c\u91c7\u7528\u50ac\u5316\u5171\u70ed\u89e3\u5de5\u827a\u5236\u5907\u4e86\u5bcc\u542b\u82b3\u70c3\u7684\u751f\u7269\u71c3\u6599\u3002\u5728\u6728\u8d28\u7d20\u4e0e\u805a\u7532\u919b\u7684\u9002\u5b9c\u6df7\u5408\u6bd4\u4f8b\u4e0b\uff085\u22365\uff09\uff0c\u751f\u7269\u6cb9\u6536\u7387\u63d0\u9ad8\u4e8625%\u81f328.3%\uff0c\u82b3\u70c3\u9009\u62e9\u6027\u63d0\u9ad8\u81f3>95%\u3002<\/p>\n
