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-FY2013) FY2012 Annual Report

In order to support the diversification of energy sources and reduce dependence on fossil fuels, this R&D aims to develop a biomass conversion process that produces high-quality biofuel as well as a biomass utilization model based on sugar production processes. In this process, high-quality biofuel is produced by catalytic reforming of oxygen-containing compounds, which is supplied from hydrothermal treatment of bagasse and/or molasses. Summary of the research in 2012FY is as follows. 1. Pre-treating of biomass: The oxygen-containing compounds such as HMF which was degraded from cellulose was obtained in the aqueous phase from sugarcane bagasse under the hydrothermal condition at 240 C, while main products were changed into furfural and acetic acid at 200 C. These are degradation compounds of hemicellulose. When the acid solution was added, the yield of oxygen-containing compounds which was derived from hemicellulose increased remarkably, indicating that the use of acid was useful to decrease the temperature. Molasses whose saccharide content reaches 35-40% is considered one of the feedstocks of this process. It was found that the viscosity of molasses depended on separation and storage conditions and inorganic compounds. Potassium must be removed from molasses before feeding to catalytic reforming, and the procedure of potassium removal was examined using some kinds of zeolites. 2. Catalytic reforming for the production of hydrocarbon bio-fuel: The concentration of the oxygen-containing compounds is very low in the pre-treating step and should be increased before catalytic reformer to reduce the energy consumption. Using some kinds of zeolites, the oxygen-containing compounds in the water was found to be concentrated in the pores. The reforming reaction data of each oxygen-containing compound were obtained, and a series of experiments to obtain the actual biofuel from sugarcane bagasse is now under progress. 3. Product research: It is confirmed that the test fuel simulating the hydrocarbon bio-fuel of this process can be prepared by mixing reagents which are the major components. The solubility of each component of the hydrocarbon bio-fuel to the conventional diesel fuels was examined. The effect of blending benzene with JIS No.2 gas oil on the fuel properties and the combustion characteristics was studied. It is concluded that benzene can be used as a diesel fuel by mixing with the conventional diesel fuels. 4. Process design: In order to reduce energy consumption, the concentration of oxygen-containing compounds using adsorbent has been examined. To evaluate energy saving impact by adsorption method, the comparison with the conventional technology like distillation method has been studied. The conceptual process flow diagram was defined, and fundamental experimental data began to be collected to produce actual biofuel from bagasse and to estimate the material and heat balance of whole process.
