LIQUEFACTION OF COAL
A solid carbonaceous material, for example a coal, is slurried in a vessel (10) with solvent and then preheated by passage through the convection section (19, 20) of a hybrid boiler (21) which also produces steam (e.g. in a radiant section 51 to satisfy process steam requirements and produce at leas...

| description | A solid carbonaceous material, for example a coal, is slurried in a vessel (10) with solvent and then preheated by passage through the convection section (19, 20) of a hybrid boiler (21) which also produces steam (e.g. in a radiant section 51 to satisfy process steam requirements and produce at least some of the electrical power required for the liquefaction process. The preheated slurry is subjected to conventional liquefaction (29) to provide gaseous material (32), normally liquid liquefaction products (34, 35, 36) and a normally solid bottoms product (33). At least a portion of the bottoms product is combusted in the combustion section (22) of the hybrid boiler (21) to provide at least some of the heat for preheating the slurry. Preferably another portion is gasified (45) to produce hydrogen, which can be employed for solvent-hydrogenation (48, 37) and/or the liquefaction (17, 15, 29). |
