英文要約Title: Research and Development of FT synthesis apparatus for the purpose of high efficiency and low cost BTL process (FY2010-FY2011) FY2010 Annual Report
Slurry-type reactor is generally used for FT synthesis reaction because this type reactor has good thermal conductivity and the heat immerged from FT synthesis reaction is easily removed. In this research, FT synthesis apparatus of a new concept, that is thermal conductivity is improved based on a fixed-bed reactor which is easily minimized and decreased its cost, multi collection bulbs are installed, and distillation process can be omitted by recovery of the FT synthesis products which is naturally separated, was examined. The basic design for new FT synthesis apparatus which has the productivity of 10 liters per a day was conducted.: Thermal supply method for FT synthesis apparatus was examined. Heating by super-heated steam and refrigeration by cooling water will be performed using the same water-jacket of the FT-synthesis reactor. Steam will be used for heating of the light oil recovery tank, cooling water will be used for refrigeration of the gasoline and water cooling tank, and chilled water will be used for refrigeration of the wax separation tank and the drying unit, respectively. : The detail design and construction of the new FT synthesis apparatus which basic design was conducted in item 1) was ordered. The apparatus was delivered and installed at National Institute of Advanced Industrial Science and Technology, Biomass Technology Research Center. Heating and refrigerating performance of the composed equipments was examined. From these results, heating performance of the light oil recovery tank and refrigerating performance of the gasoline and water cooling tank and the wax separation tank, were sufficient. However heating performance of the reactor was insufficient. As the result of investigation by the manufacturer, the flow amount of super-heated steam was too little and the temperature of the steam was decreased, because the inner diameter of the steam pipe was 10.7 mm that was too small. Therefore the pipe was changed to that of 32 mm in inner diameter and the sectional area of the pipe was 9 times of original one. Once again, the heating test was performed and the temperature of the super-heated steam at the entrance of the reactor was increased up to 375 degrees. The inside temperature of the reactor could increase up to 180 degrees at the bottom of the reactor in which the catalyst was existed. : FT synthesis reaction was carried out in the FT synthesis apparatus using the synthesis gas which was produced by gasification of woody biomass. The inside temperature of the reactor was adjusted at 300 degrees and the inside pressure was also adjusted at 4MPa. The reaction was continued for more than 4 hours at the stable state, supplying the synthesis gas at the flow rate of 60 NL/min. The original gas contained 60 % of H2 and 30% of CO. The flow rate of the off-gas which was exhausted from the apparatus was 20NL/min and the composition of the gas was 25% of H2, 25% of CO and 30% of CH4. After the end of the reaction, 4.3 kg of liquid was obtained from the light-oil recovery tank and 62g of liquid was also obtained from the gasoline and water recovery tank. From these results, FT synthesis reaction was thought to be successfully carried out.
