摘要： A solvation process for producing deashed solid and liquid hydrocarbonaceous fuel from coal. Raw coal is slurried with a solvent comprising hydroaromatic compounds in contact with hydrogen in a first zone operating at a low residence time, a relatively high temperature and a relatively low hydrogen pressure to dissolve hydrocarbonaceous fuel from coal minerals by transfer of hydrogen from hydroaromatic solvent compounds to hydrocarbonaceous material in the coal. The solvent is then treated with hydrogen in a second zone at a longer residence time, a relatively low temperature and a relatively high hydrogen pressure to replenish the solvent with hydrogen.

摘要： A solvation process for producing deashed solid and liquid hydrocarbonaceous fuel from carbon. Raw coal is slurried with a solvent comprising hydroaromatic compounds in contact with hydrogen in a first zone to dissolve hydrocarbonaceous fuel from coal minerals by transfer of hydrogen from hydroaromatic solvent compounds to hydrocarbonaceous material in the coal. The solvent is then treated with hydrogen in a second zone to replenish the solvent with hydrogen. Hydroaromatic solvent and residue coal minerals are recycled to the first zone.

摘要： A solvation process for producing deashed solid and liquid hydrocarbonaceous fuel from coal. Raw coal is slurried with a solvent comprising hydroaromatic compounds in contact with hydrogen in a first zone at a relatively high temperature to dissolve hydrocarbonaceous fuel from coal minerals by transfer of hydrogen from hydroaromatic solvent compounds to hydrocarbonaceous material in the coal. The solvent is then treated with hydrogen in a second zone at a lower temperature to replenish the solvent with hydrogen. Forced cooling of the slurry between zones accomplishes many significant improvements in the process.
摘要翻译：用于从煤生产脱沥青的固体和液体含烃燃料的溶剂化方法。原煤在相对较高的温度下在第一区域中与包含与氢接触的水溶性化合物的溶剂制浆，以通过将氢气从水溶性芳族溶剂化合物转移到煤中的含烃材料来溶解来自煤矿物质的烃类燃料。然后在较低温度的第二区域用氢气处理溶剂，以用氢气补充溶剂。区域之间的浆料的强制冷却在该过程中实现了许多显着的改进。
