| 摘要 |
A method of feeding solid carbonaceous material to a gasifier operating under conditions of high temperature and pressure by forming a slurry of the carbonaceous material and a liquid vehicle, raising the internal pressure of the slurry to the operating level of the gasifier, drying the carbonaceous material by entraining the carbonaceous material in a hot gas stream, and thereafter separating the carbonaceous material and feeding the carbonaceous material to the gasifier. The method is adaptable to using the gasifier effluent to dry the carbonaceous material and includes using process materials such as char accumulated from the process and condensing steam to provide a portion of the source of carbonaceous materials and vehicle for the slurry. |
