Abstract
A process for converting cellulosic materials, including waste cellulosic materials, into a useful, low-sulfur and low-ash fuel by subjecting the cellulosic feed material to an autoclaving treatment at a controlled elevated temperature and controlled high pressure for a period of time to convert the moisture and a portion of the organic constituents therein to a gaseous phase and to effect a controlled thermal restructing of the chemical structure thereof, producing a solid carbonaceous or coke-like product and a by-product fuel gas. It is further contemplated that the low-sulfur coke product can be comminuted to a desired particle size range and admixed with high-sulfur fuel oils, providing a blended liquid slurry fuel of an acceptable sulfur content.
