High Yield Production of Levoglucosan via Catalytic Pyrolysis of Cellulose at Low Temperature<\/strong><\/p>\n

Recently, Dr Li-Qun Jiang (Associate Prof., Institute of Biological and Medical Engineering, Guangdong Academy of Sciences), Prof. H Li (Guizhou University) and Prof. Zhen Fang<\/strong> published an article in Fuel about levoglucosan production from catalytic pyrolysis of cellulose with acid-base bifunctional magnetic Zn-Fe-C catalysts.<\/p>\n

Catalytic pyrolysis of cellulose to levoglucosan in improved yields was achieved with acid-base bifunctional magnetic Zn-Fe-C catalysts. Among tested catalysts, Zn4<\/sub>@Fe-C500 <\/sub>could not only increase levoglucosan yield by 5.4 times compared with non-catalytic cellulose pyrolysis at 300 \u00b0C, but also help lower reaction temperature by 200 \u00b0C due to acid-base site synergistic effect. Furthermore, the levoglucosan yield (80.1 wt%) from catalytic cellulose pyrolysis at 300 \u00b0C was much higher than that commonly conducted at 500 \u00b0C without catalyst (60.1 wt%). Thermogravimetric and kinetic analysis disclosed levoglucosan formation mechanism. Importantly, Zn4<\/sub>@Fe-C500<\/sub> catalyst was highly recyclable with little deactivation after 5 consecutive cycles. This study exhibited great potential for industrial levoglucosan production from cellulose at low temperatures. Related results were published in Fuel:<\/p>\n
