Abstract
A method for producing carbonaceous-derived solid fuel products comprising subjecting a carbonaceous material to a temperature sufficient to remove a substantial portion of water inherent in said carbonaceous material, pyrolyzing at least a portion of the dried carbonaceous material to form a carbonaceous-based char material and simultaneously recover carbonaceous-based tar by-products and contacting at least one material selected from the group consisting of the dried carbonaceous material and the carbonaceous-based char material with a water-in-tar emulsion, said emulsion being prepared from said recovered carbonaceous-based tar by-products.
