Abstract
Water-solid fuel slurries suitable for use as feed to a solid fuel gasifier are prepared by forming a ground solid fuel-water mixture containing about 35-55 wt. % water, adding sufficient organic liquid to form a pumpable slurry, pumping the slurry through a heating zone to a separator, and separating organic liquid from the fuel-water mixture.
Claims10
In a process for the gasification of a solid fuel which comprises adding water to a finely-divided solid fuel to form a mixture having a total water content between 35 and 55% by weight, the improvement which comprises adding sufficient organic liquid of a type selected to improve the pumpability of said mixture to the mixture to form a pumpable slurry, heating the resulting slurry under pressure sufficient to maintain the water in liquid phase, separating at least a portion of the organic liquid from the heated slurry and then injecting the remaining mixture into a solid fuel gasification zone.
