摘要： A process for drying coal is provided in which coal is passed into a fluidized bed reactor and heated to a predetermined temperature. The dried coal is then fed to a cooler where the temperature of the product is reduced to approximately 200 degrees Fahrenheit and water is added to further passivate the coal.

摘要： A multistage process for drying coal in which coal is passed into a first fluidized bed reactor at a temperature of 300 to 550 degrees Fahrenheit, air is fed into the first reactor in order to maintain the density of the fluidized bed at from 20 to 50 pounds per cubic foot, and from about 40 to about 60 percent of the water from the coal is removed from the coal and the first reactor. The partially dried coal is then fed to a second fluidized bed reactor which is maintained at a temperature at least 50 degrees Fahrenheit higher than that present in the first reactor, and substantially all of the water remaining in the coal is removed from the coal.

摘要： A process for preparing an irreversibly dried coal. In the first step of the process, a first fluidized bed reactor with a bed whose density is from about 30 to about 50 pounds per cubic foot and whose temperature is from about 480 to about 600 degrees Fahrenheit is contacted with a coal with a moisture content of from about 15 to about 30 percent, liquid phase water, inert gas, and air. The comminuted and dewatered coal produced in the first fluidized bed reactor is then passed to a second fluidized bed with a density of from about 30 to about 50 pounds per cubic foot and a temperature of from about 215 to about 250 degrees Fahrenheit, to which water, inert gas, and from about 0.5 to about 3.0 weight percent of mineral oil with an initial boiling point of at least about 900 degrees Fahrenheit is also fed; the temperature of the comminuted and dewatered coal is reduced to the temperature of from about 215 to about 250 degrees Fahrenheit in less than about 120 seconds.
