Zusammenfassung: | The invention discloses an oil shale gasification technology and a special apparatus thereof. The gasification technology is characterized in that raw materials comprise 50-70% of an oil shale and coal mixture (containing 20-100% of oil shale), water and 0.7-2% of a dispersant, and the technology comprises the following steps: 1, preparing a slurry according to the following scheme A or B: A: mixing the raw materials, and grinding to obtain the slurry, wherein the particle size of the solid particles of the slurry is lower than 0.5mm; and B: crushing the oil shale and coal mixture to below 0.5mm, and uniformly mixing the crushed mixture with water and the dispersant to obtain the slurry, wherein the solid content of the slurry in the scheme A or B is 58-70%; and 2, reacting the slurry with a gasification agent under 0.01-8.7MPa at 1200-1700DEG C to generate synthetic gas, wherein the input ratio of the slurry to the gasification agent is 0.6-2.5kg/m . The synthetic gas obtained through the gasification technology contains no impurities, has high low-calorific value, and can be directly used as a fuel. |
