Abstract of the Disclosure A process for agglomerating bituminous fines into a useful low-sulfur particulated fuel by subjecting the bitumin- ous fines to an autoclaving treatment at a controlled elevated temperature and controlled high pressure for a period of time sufficient to convert the moisture and a portion of the organic constituents therein to a gaseous phase and to effect a con- trolled thermal restructuring of the chemical structure thereof, providing a solid agglomerated coke-like product and a by- product fuel gas. It is further contemplated that the bitu- minous fines feed material can be subjected to a preliminary mechanical separation treatment to extract some of the impur- ities therein prior to the autoclaving step. It is further contemplated that the feed material can comprise bituminous fines blended with up to about 50% by weight of particulated cellulosic materials, such as agricultural and forest waste materials, which similarly are converted during the autoclaving treatment to a useful solid coke product.
