Process for distilling solid carbonaceous material
Patent
·
OSTI ID:5362198
A process of destructive distillation of solid carbonaceous materials is described which consists in subjecting the material to the action of steam at a preheating temperature by percolating the steam through the material to cause a distillation. The residuum from the distillation is subjected to the action of superheated steam under pressures above atmospheric by percolating the steam therethrough at a destructive distillation temperature. Saturated steam is passed through the residuum of the second step, this steam being raised in temperature and then used in preheating.
