COAL DRYING METHOD AND SYSTEM

摘要

The present invention provides a method and system for drying coal using activated alumina. The method and system dries the coal by combining coal with the activated alumina. While in combination, the mixture is agitated to maximize surface contact between the activated alumina and the coal. As the coal contact the activated alumina, the surfactant moisture on the coal is then absorbed by the activated alumina. The activated alumina allow for the water molecules to pass into the sieves, thus being removed from the coal. After a period of agitation, the method and system thereby separates the activated alumina and the coal.

主权项

1. A method for drying coal comprising:
combining a first volume of coal with a second volume of activated alumina; drying the coal through contacting engagement of the coal with activated alumina such that moisture content of the coal is reduced by the activated alumina; and separating the activated alumina from the coal.
