摘要:
The ash content of raw coals, lignite, and other carbonaceous materials is reduced by leaching the highash material with an aqueous acidic waste product produced by a Fischer-Tropsch reaction. The acidic aqueous waste is mixed with coal and process conditions are described. The claim takes advantage of using otherwise uneconomic coal, lignite or other carbonaceous material by upgrading the material to a suitable feedstock for combustion in a power plant or gasifier.
摘要(中):
原料煤,褐煤和其他碳质材料的灰分含量通过用由费 - 托反应产生的含水酸性废物产物沥滤高而害羞的灰分材料而降低。 将酸性含水废物与煤混合并描述工艺条件。 索赔利用其他不经济的煤炭,褐煤或其他碳质材料,通过将材料升级为合适的原料用于在发电厂或气化炉中燃烧。 p>
