英文要約Title: Technological development of process from manufacturing chemicals derived from non-edible plant resources. / Research & development No. 2 Development of an integrated manufacturing process from woody biomass to chemicals / Development of an integrated manufacturing process from woody biomass to chemical materials for plastics. (FY2013-FY2019) FY2013Annual Report

The aim of this project is the development of an integrated manufacturing process to produce chemicals from non-edible woody biomass. To utilize wood it is necessary to separate three main components, namely lignin, cellulose and hemicellulose effectively with keeping each activity. And also separated materials should be utilizable in the following process. Four technical groups were set for effective development of each technical issue, components separation, lignin utilization, cellulose utilization, and utilization of dehydrated polysaccharides. These groups exchange information and samples to build up an integrated process.
(1)Separation group tried to improve alkaline pulping process for getting less condensed lignin for the further utilization and to improve condition of hydrothermal treatment to get soluble lignin more than 70% with water/acetone solution. Several kinds of separated component were provided for other groups in order to evaluate them for developing their utilization processes.
(2)Lignin utilization group decreased lignin molecular weight or got phenolic monomer compounds with several methods. These modified lignin or fragments were supplied as materials of phenol resin or high quality epoxy resin, and it was clarified lignin resin could be prepared as a substitute of phenol resin.
(3)Cellulose utilization group investigated about novel pretreatment methods to transform woody biomass to levulinic acid (LA) or hydroxymethylfulfural (HMF). As a result, LA was directly obtained in 72% yield (based on α-cellulose) from woody biomass with catalysts. Besides HMF was obtained in 99% conversion, 72% yield from unbleached pulp with water under suitable conditions.
(4)Sugar utilization group developed the method to convert unbleached pulp as a model and pre-extracted liquor which contained hemicellulose mostly, into monosaccharaides.
Next, the conversion process to 2-deoxy-scyllo-inosose (DOI) was developed using these monosaccharaides. In addition, ricinoleic acid was produced by fermentation process with transformed yeast from the monosaccharaides. Production of isosorbide from C6 monosaccharaides was developed using the novel catalyst, and then the target yield in this year was obtained with solid acid as a catalyst.
