Chemical Utilization of Forest Resources

As the limitation of the world's fossil raw materials has been widely recongnized, a world-wide increase of interest can be noticed in the field of chemical utilization of wood and biomass in recent years. In this paper, the necessity and potential significance of the only renewable resource, biomass, especially the forest biomass for the production of chemicals in meeting future chemical needs were described. The economic feasibility for production of certain major chemicals from lignocellulosic material at present and in the future was discussed. The production processes, the main chemical products from cellulose, hemicellulose and lignin, and some of their uses both as macromolecular and low-moleculear-weight compounds are briefly introduced. The methods of wood processing being used and tested for production of chemicals, such as pyrolysis, gasification, liquefaction and saccharification were also mentioned. The new technology being developed, such as the use of enzymes for cellulose hydrolysis, the fermentation and use of solvents for separation of lignin and cellulose, the researches required for chemical utilization of woody material in the future were figured out. Finally, some suggestions to the development of producing chemicals from forest resource in China were made.
