英文要約Title : Project to Develop Next-generation Technology for Strategic Utilization of Biomass Energy. Development of Biomass Conversion Process for Producing High-quality Biofuel Using Hydrothermal Pretreatment and Catalytic Reforming with Zeolite (FY2012-FY2015) FY2014 Annual Report

In order to support the diversification of energy sources and reduce dependence on fossil fuels, we aim to develop a biomass conversion process producing high-quality bio-fuel based on a biomass utilization model integrated with sugar production processes. The bio-fuel is produced by catalytic reforming of oxygen-containing compounds (OCCs), which are supplied from hydrothermal treatment of bagasse and/or molasses. We have succeeded in obtaining real bio-fuel sample those main component was BTX aromatics from bagasse supplied from sugar plant, and also confirmed that the produced bio-fuel could be blended at the ratio of around 20% into the conventional diesel fuel. Annual bio-fuel production amount is estimated to be equivalent to 4-5% of fossil fuels consumed for the power plant in the remote island in Japan when this process is integrated with sugar plant there. In order to establish whole system and process, we have obtained the fundamental data which can be used for equipment design at each section in 2014FY. In addition, we have found new process to remove potassium from molasses before hydrothermal treatment. Summary of the research in 2014FY is as follows. 1. Pre-treating: The decreasing of water/biomass ratio is needed for energy saving of hydrothermal treatment. The bagasse pretreated by wet milling made possible to decrease the biomass/water ratio, up to 1/5, during the hydrothermal treatment without decreasing the yield of OCCs. Large part of potassium can be removed from molasses as composite salt before hydrothermal treatment. Main product of hydrothermal treatment of molasses is 5-HMF, which is converted into BTX at catalytic reforming section. 2. Catalytic reforming for the production of hydrocarbon bio-fuel: Before catalytic reforming, aqueous solution of OCCs, effluent of hydrothermal treatment, is fed into adsorption column to concentrate OCCs in the adsorbent. The extra water accompanying with OCCs are removed by mechanical or drying way to achieve further concentration of OCCs. The highly concentrated OCCs serve for increasing the bio-fuel yield in the reforming reaction and reducing the processing cost. The fundamental data such as the effect of temperature and contact time are obtained to build the reaction model and reaction simulator. 3. Product research: The effect of the bio-fuel composition on the fuel properties and combustion characteristics of the bio-fuel/conventional diesel fuel blend was studied and concluded that they have almost the same start-ability and stability in the engine operation, the same thermal efficiency and the same exhaust emissions at high load conditions as conventional diesel fuel. 4. Process design: We have built the reaction model and reaction simulators for equipment design of hydrothermal treatment and catalytic reforming section.
