PROCESS FOR THE PREPARATION OF A COMBUSTIBLE MIXTURE OF COAL IN WATER

摘要

There is disclosed a novel fuel slurry comprising a mixture of finely ground coal constituting 65 to 70 percent of the fuel, water, a wetting/dispersing agent for the coal constituting 0.5 to 5 percent of the fuel and a suspending agent for stabilizing the fuel slurry which agent constitutes a clay such as attapulgite clay in the dry, pregelled or predispersed form. Other clays can be employed as a stabilizer, as a predispersed non-gelling montmorillonate clay. If the coal slurry is to be used immediately the clay or other gelling agent is not necessary to maintain suspension stability.
