1 High Efficiency Waste Cooking Oil Refinery Plant Can Produce Portable Biomass Energy Wataru IIJIMA, Yuichi KOBAYASHI, Kazuhiro TAKEKURA, Hitoshi KATO, Ken TANIWAKI Biomass National Agricultural Research Center, NARO, JAPAN APAN Field Server/Sensor Network Workshop 29. Aug. 2007

2 Contents W. IIJIMA 29/Aug./2007 Background About Biodiesel Fuel Problems in Traditional Process Introduction of STING-process Portable Production Units Production Costs Conclusions

3 W. IIJIMA 29/Aug./2007 Background · Portable Energy Station is useful for field server in no-electricity area. · Carbon-neutral Energy is desired. · Biodiesel Fuel is one of promising fuel for alternative diesel fuel. · There is a some problems for portable plant using traditional biodiesel production process. · We would like to suggest another technologies.

4 W. IIJIMA 29/Aug./2007 Biodiesel Fuel Biodiesel Fuel is Biomass-oriented Alternative Diesel Fuel Fatty Acid Methyl Ester (FAME) from Plant Oils and Animal Fats by Transesterification and Esterification Hydrocarbon from Plant Oils and Animal Fats by Pyrolysis from Plant Oils and Animal Fats by HDO (removal Oxygen by Hydrogen) from All Biomass by FT (Fisher-Tropsch) process

5 W. IIJIMA 29/Aug./2007 Methyl Ester Production from Oils and Fats Free Fatty Acid Methanol Fatty Acid Methyl Ester CH 3 OH R 4 COOCH R 4 COOHH2OH2O Water Triacylglycerol (Fat and Oil) Methanol Glycerol Fatty Acid Methyl Esters CH 2 OCOR 1 CHOCOR 2 CH 2 OCOR 3 3CH 3 OH CH 3 OCOR 1 CH 3 OCOR 2 CH 3 OCOR 3 CH 2 OH CHOH + +

8 W. IIJIMA 29/Aug./2007 Problems in Traditional Process · Can't esterified Free Fatty Acid · Need large amount of water for washing · Need many process in purification and neutralization of fuel and waste water · Produce by-products such as glycerol

9 W. IIJIMA 29/Aug./2007 STING-process Simultaneous reaction of Transesterification and crackING The Complex Reaction of Methanolysis, Pylolysis, Cracking, and Methlation in Supercritical Methanol 460ºC, 20MPa, 5min STING-process Non-Catalytic Process No Glycerol Production Improvement of the Fuel Characteristics

IIJIMA 29/Aug./2007 STING-process Oil Ddehydration Transesterification Methanol Residues Deacidification Catalyst Methanol Fuel Water Dehydration Separation Evaporation 0.2% Glycerol Reaction

12 W. IIJIMA 29/Aug./2007 STING Plants Labo-scale Bench-scale Compact Type Verification Test Plant by HARAKOSAN CO., Ltd. Type 1 Type 2 Automatic Operation by 81 Co., Ltd. Manual Operation Lower Price by Taishou rika K.K.

13 1,500 W. IIJIMA 29/Aug./2007 Bench-scale Plant 3,300 1,500 1,500 mm Production Ability: 5~25 L/H Reaction Pressure : Max. 25 MPa Reaction Temperature : Max. 600ºC Reaction Time: 5 min Power Consumption: Start Up: 9kW Steady State: 2~4kW

14 W. IIJIMA 29/Aug./2007 Portable Energy Station STING Plant Oil (10L) Fuel (11L) Methanol (5L) External Power (4L) Standard Fuel Production Unit Oil (10L) Methanol (5L) (4L) STING Plant Fuel (8L) Generator (3L) Standalone Fuel Production Unit STING Plant Oil (10L) Methanol (5L) Generator (4L) Fuel (11L) Electricity (50~60kW) Standalone CoGeneration Unit Hot Water

15 W. IIJIMA 29/Aug./2007 Production Costs The trial condition Price of Instrument: 100,000~ 133,333 (\15,000,000~\20,000,000) depreciate for 8 years Power:Three-phase 200V, 9kW Operation Condition:24hours continuous running Availability 90%) Fuel Production Quantity:6L/h 3,888L/Month) Standard Fuel Production Unit Electricity Cost 0.12/L (\ 19/L) Depreciation Cost 0.27/L (\ 40/L) + Material costs and Personnel costs Standalone Fuel Production Unit Electricity Cost 0/L (\ 0/L) Depreciation Cost 0.38/L (\ 57/L) + Material costs and Personnel costs Standalone Cogeneration Unit Electricity Cost 0/kWh (\ 0/kWh) Depreciation Cost 0.05/kWh (\ 7/kWh) + Material costs and Personnel costs

16 W. IIJIMA 29/Aug./2007 Conclusions · Portable Energy Station was suggested for rural area energy supply. · STING-process is no-catalytic and no-by-product process. · STING-process was suitable for Portable Energy Station. · Bench-scale portable plant is now developing. · Production costs was about 0.4/L without material costs and personnel costs.
