FOERFARANDE FOER OMVANDLING AV CELLULOSAHALTIGA UTGAONGSMATERIAL TILL KOKSARTAT BRAENSLE ELLER BRAENSLESUSPENSION. ADDITIONAL TO PATENT 61202 - TILLAEGG TILL PATENT 61202

摘要

Cellulosic material, is converted into a useful, low-sulfur and low-ash coke type fuel by autoclaving at a temperature of 750 to 1250 DEG F and pressure of at least 1000 psi 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 restructuring of the chemical structure of the cellulosic material, producing a solid coke-like product and a by-product fuel gas. The low- sulfur coke product can be comminuted and admixed with high- sulfur fuel oils, providing a blended liquid slurry fuel of acceptably low- sulfur content. IMAGE
