Summary:

This report describes our initial evaluation of a process designed to produce premium-quality solid fuel from Powder River Basin (PRB) coal. The process is based upon our experience gained by producing highly-reactive, high-heating-value char as part of a mild-gasification project. In the process, char containing 20 to 25 wt % volatiles and having a gross heating value of 12,500 to 13,000 Btu/lb is produced. The char is then contacted by coal-derived liquid. The result is a deposit of 6 to 8 wt % pitch on the char particles. The lower boiling component of the coal-derived liquid which is not deposited on the char is burned as fuel. Our economic evaluation shows the process will be economically attractive if the product can be sold for about $20/ton or more. Our preliminary tests show that we can deposit pitch on to the char, and the product is less dusty, less susceptible to readsorption of moisture, and has reduced susceptibility to self heating.
