英文要約Title: Technology development of manufacturing processes for non-edible plant-derived chemicals. / Development of an integrated process for manufacturing chemical derived from woody plant resources /Development of an integrated process for manufacturing chemicals from woody biomass. (FY2013-FY2019) FY2015Annual Report

Developing an integrated manufacturing process to make chemicals from non-edible woody biomass, each member is acting vigorously as the R&D schedule. It is important to determine the method to separate three main components effectively. And also separated materials should be utilizable in the following process. Four technical groups were conducting the effective developments 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 the economic situation of each process and possibility to utilize the separated components with the following groups. Due to the cost, the production feasibility, and evaluations to use, alkali cooking was selected as the most feasible method to separate 3 components of wood. The important point was to prevent condensation reaction of lignin during cooking. Moreover the classification of lignin by molecular weight was conducted for resin.
(2) Lignin utilization group found out that important factors were the molecular weight and temperature behavior of lignin to utilize for resin. The research to decrease lignin molecular weight into the proper level was started from the lignin which was isolated from black liquor of soda cooking. And the new high molecular polymer was synthesized from vanillin which would be produced with the modified soda cooking.
(3) Cellulose utilization group investigated about novel pretreatment methods to transform woody biomass to levulinic acid (LA). As a result, LA was directly obtained in 80mole% yield (based on α-cellulose) from woody biomass with catalysts. Besides the new catalyst was found to synthesize methyl levulinate from woody biomass.
(4) Sugar utilization group developed the method to convert unbleached pulp and pre-extracted liquor which contained hemicellulose mostly, into monosaccharaides. The enzyme cost could be decreased to less than 20yen/kg. Next, the conversion process to 2-deoxy-scyllo-inosose (DOI) was developed higher efficiency. In addition, production rate of 3-hydroxypropionic acid was improved three times higher than ever. Production of isosorbide from C6 monosaccharaides was developed using the novel catalyst, and then the plan for actual production was made.
