Abstract
PURPOSE: To effectively liquefy low-grade coal, by subjecting a mixture of pulverized coal treated by oxidation and a heavy oil to a heat treatment at a specific temperature.
CONSTITUTION: A low-grade stock coal, e.g., brown coal, weathered coal, etc., is pulverized into particles passing through a 300-mesh sieve, and the pulverized coal is heated at approx. 250°C or lower and at the same time is oxidized by supply of oxygen or air until oxygen-added substances are formed or alkali-soluble high- molecualr organic acid (humic acid) is formed. Then, 1pt.wt. oxidized coal is mixed with 1W5pts.wt. heavy oil, heat-treated with stirring at 300W420°C, preferably 350W400°C for 0W60min for dissolution and then filtered for removal of undissolved substances.
