| 摘要 |
The present invention relates to a gasification system where a bulky carbonaceous feedstock is pyrolyzed at lower temperature (600-1000 C) to bring about a significant reduction in it's volume; and the pyrolysis products are transferred into a smaller reformer at 1200 C to carry out an efficient conversion to syngas. Carbonaceous material constitutes all forms of carbon-containing substance and it includes all fossil fuel, biomass, marine vegetation, animal waste, and industrial organic wastes. Pyrolysis reaction at 600-1000 C produces C1-C8 flue gas and solid char and cokes. Reforming reaction here is more specifically defined as that carbon atom reacts with steam or carbon dioxide gas at 1200 C and reforms into CO gas and all hydrogen atoms are reduced to H2 gas.; It is also referred as endothermic reduction reaction, irregardless of physical and chemical states of carbon, it reacts steam or CO2 gas at 1200 C and above, and reforms into CO and H2 gas, called syngas. No catalyst is needed. |
