Biomass as a Raw Material for the Liquefied Wood Production

Wood biomass is one of the most abundant and accessible renewable resources available to men. All the main chemical components of wood biomass as lignocellulosic material are high-weight-molecular polymers and form an interwoven network in the wood cell wall ; consequently we can say that the wood biomass is a natural polymer with polyphenolic character. With growing emphasis on sustainable development, new methods involving alternative biomass use are being explored. Great efforts are directed to new technology development for achieving effective wood biomass utilization, and obtaining ecologically acceptable materials on their base. Particularly interesting is application of wood biomass as a feedstock for producing polymers that could replace a part of the conventional fossil oil based polymers. Wood biomass liquefaction is novel method, and its aim is to convert wood biomass material in biodegradable polymer materials and increase percentage of its utilization. Maximum attention attracted wood biomass liquefaction in presence of some organic reagents and the most interesting are two methods. The first one is the preparation in presence of phenol, which resulted in liquefaction products rich with phenol units. The second liquefaction method was achieved in presence of polyhydric alcohols. The aim of this paper was to make a overview of previous researches related to wood biomass liquefaction and its potential application in the wood industry.
