    • A method of upgrading coal which comprises: pulverizing low-grade coal; mixing the pulverized low-grade coal with an oil to form a slurry; heating the slurry to or above the boiling point of water to vaporize the water contained in the low-grade coal and dehydrate the coal; compressing a vapor mixture of the steam resulting from the slurry heating and that part of the oil which has vaporized simultaneously and thereby elevating the temperature and pressure of the vapor mixture; and supplying the vapor mixture increased in temperature and pressure by the compression and utilizing this vapor mixture as a high-temperature heat source to heat the slurry. In the method, the vapor mixture before being compressed is brought into contact with an oil in a liquid state. This method is a process in which low-grade coal containing water in a large proportion and hence having a low calorific value is dewatered in an oil to thereby upgrade the coal to a high-calorie fuel for thermal power generation, wherein the vapor mixture to be supplied to a compressor can be purified.
    • 一种提炼煤的方法,包括:粉碎低档煤; 将粉碎的低品位煤与油混合以形成浆料; 将浆料加热至或高于水的沸点,蒸发低级煤中所含的水分,使煤脱水; 压缩由浆料加热产生​​的蒸汽的蒸汽混合物和同时蒸发的部分油,从而提高蒸汽混合物的温度和压力; 并通过压缩将蒸汽混合物的温度和压力提高,并利用该蒸气混合物作为高温热源来加热浆料。 在该方法中,压缩前的蒸气混合物与液态的油接触。 这种方法是一种方法,其中大部分含量低,因此具有低热值的低含量煤在油中脱水,从而将煤升级为用于热发电的高热量燃料,其中蒸汽混合物 供应给压缩机可以净化。
