ABSTRACT:
A process for agglomerating bituminous fines into a useful low-sulfur particulated fuel by subjecting the bituminous 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 controlled 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 bituminous fines feed material can be subjected to a preliminary mechanical separation treatment to extract some of the impurities 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.
