- Abstract:
-
Paulownia was liquefied by water in an autoclave in the reaction temperatures range of 280—360℃with iron powder as the catalyst.Effect of reaction temperature to biomass direct liquefaction process and thecomposition of heavy oil and water—·soluable oil were investigated through compared to the functional group in—frared spectrum differences between raw material and solid residue.The experimental results show that thecourse of liquefaction was significantly influenced by the reaction temperature.The solid residue,heavy oiland water—·soluble oil obtained at different reaction temperatures were analyzed by Fourier Transform InfraredSpectrophotometer(FTIR).The analytical results show:(1)the cellulose and hemi—cellulose is entirelyconsumed at 320℃,and lignin are depolymerized at 280℃.but during the reaction temperature solid resi—due also contain aromatic ring structure.(2)The functional group of heavy oil is not change during the reac·tion temperatures.(3)The heavy oil and water—soluble oil is complex compound that contain hydrocarbons,aldehydes,ketones,earboxylic acids,phenols,esters and other compounds.
