Experimental Study of the First Pyrolysis of Cellulose

Flash pyrolysis of cellulose is done on the laser pyrolysis experiment device, from which some water-loving yellow substances are collected, which is confirmed as active cellulose. HPLC analysis shows that the chief constituent of this yellow substances are glucose, fructose and oligosaccharide, and whose yield are determined. The research indicates that: at high-radiation power, glucose is not the only production decomposing from oligosaccharide, and there is another production decomposing from oligosaccharide which will compete against glucose. At last, the mechanism of the first pyrolysis of cellulose is analysed.
