| ABSTRACT |
|
Rice straw is catalytically gasified under nickel catalysts at different reaction temperatures from 150 to 300℃. The influences of several parameters such as reaction time, support, sodium carbonate, amount of water and reducing temperature of nickel catalyst have been studied. A marked effect of sodium carbonate is observed for the production of oils and nickel catalyst supported on kieselguhr shows an excellent activity for the gasification of rice straw. These results also show that the yield of hydrogen and carbon monoxide are largely increased with the higher reducing temperature of nickel catalyst. |
