In order to widen the application of wood liquefaction products,to improve the added value of wood products,and to realize the highly effective uses of wood,on the basis of studying the characteristics of phenolated wood,the ideas of preparing carbon fiber from wood-phenol liquefaction products and its technical route were proposed.

Effects of carbonized temperature on microstructure of carbon fiber precursors prepared from liquefied wood

Emphasis was put on methods of liquefaction,liquefaction mechanism of principal component of wood and the application of liquefied wood.

The carbon fiber precursors were prepared from liquefied wood in phenol by adding hexamethylenetetramine and soaking in the solution containing hydrochloric acid and formaldehyde as the main components.

In order to release the deficient situation of mineral resources, expand the application area of biomass materials and enhance its using value, we carry out the research of the Giant reed liquefaction in phenol with acid as catalyzer.

To investigate the effects of temperature,time,the content of sulfuric acid catalyst and liquid ratio of phenol to particleboard on the liquefaction in phenol,and to find the optimum technological parameters,based on the analysis of affecting factors,this study has found the optimum technological parameters with orthogonal experiments.
