摘要： Thus, a novel process for producing a passivated coal material has been disclosed, comprising the steps of (a) drying a coal material by heating said coal material in the presence of a first gas comprised of less than about five volume percent of oxygen until said coal material has a moisture content of from above about 1 to about 20 weight percent, thereby producing a partially dried coal material, wherein said coal material is selected from the group consisting of lignitic coal, sub-bituminous coal, bituminous coal, coal char, and mixtures thereof; (b) heating said partially dried coal material to a temperature of from about 100 to about 600 degrees Fahrenheit, thereby producing a heated partially dried coal material; (c) charging said heated partially dried coal material to a fluidized bed reactor; (d) feeding a second gas with an oxygen content of from about 6 to about 15 volume percent into said fluidized bed reactor; (e) contacting said heated partially dried coal material with said second gas while maintaining said heated partially dried coal material at a temperature of from about 450 to about 650 degrees Fahrenheit; and, thereafter, (f) removing water from said heated partially dried coal material until no more than about 1 weight percent of water remains in said heated partially dried coal material.

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： Aa process for preparing an irreversibly dried coal which utilizes a fluidized bed reactor with a fluidized bed density of from about 20 to about 40 pounds cubic feet which is at a temperature of from about 150 to about 200 degrees Fahrenheit. To this reactor is fed coal with a moisture content of from about 25 to about 30 percent, an oxygen content of from about 10 to about 20 percent, and a volatile matter content of from about 35 to about 45 percent; and it is subjected to a temperature of from about 150 to about 200 degrees Fahrenheit for from about 1 to about 5 minutes while simultaneously being comminuted and dewatered. The comminuted and dewatered coal is passed to a second fluidized bed reactor with a fluidized bed density of from about 20 to about 40 pounds per cubic foot and a reactor temperature of from about 480 to about 600 degrees Fahrenheit. Also fed to this second fluidized bed reactor is from about 0.5 to about 3.0 weight percent of mineral oil.

To this reactor is fed coal with a moisture content of from about 25 to about 30 percent, an oxygen content of from about 10 to about 20 percent, and a volatile matter content of from about 35 to about 45 percent; also fed to this reactor is from about 0.5 to about 3.0 weight percent (by weight of dried coal) of mineral oil with an initial boiling point of at least about 900 degrees Fahrenheit. A coated coal is produced in the reactor, and it is subjected to a temperature of from about 480 to about 600 degrees Fahrenheit for from about 1 to about 5 minutes while simultaneously being comminuted and dewatered. The comminuted and dewatered coal is passed to an elutriator in which said comminuted and dehydrated coal is contacted with air and separated into a coarse fraction and a fine fraction. The coarse fraction from the elutriator is fed to the fluidized bed, while the fine fraction from the elutriator is quenched to reduce its temperature to ambient temperature within about 5 seconds.
