NOVELTY - A carbon-rich coal comprises (pts. wt.): natural raw coal composite raw material (50-55), modified plant optimal material (45-55), environmental-protection cleaning agent (3-5), energy convergence accelerating agent (8-12) and mixed double-polar binder (4-6), preferably natural raw coal composite raw material (40-50) (containing 10-25% of low-value coal gangue, coal slurry and middlings), modified plant optimal material (45-58), environmental-protection cleaning agent (5-7), energy convergence accelerating agent (6-12) and mixed double-polar binder (4-6).    USE - Carbon-rich coal used in industry and civil use.    ADVANTAGE - The coal has improved and regrouped structure, attribution, performance and quality, thus obtaining highest efficiency and better environment protection feature; prolongs combustion time, thus increasing combustion value; and has thermal efficiency, saves energy, eliminates pollution and protects the environment. It has strong reproducibility, thus saving original coal carbon energy, and has conservation ratio is 50-80. The coal has calories reaching to 6000-7200 kilocalories, sulfur content of 0.2-0.5%, Ringelmann smoke degree of 20-40%, and fixed carbon content of 50-65%.    DETAILED DESCRIPTION - Carbon-rich coal comprises (pts. wt.): natural raw coal composite raw material (50-55), modified plant optimal material (45-55), environmental-protection cleaning agent (3-5), energy convergence accelerating agent (8-12) and mixed double-polar binder (4-6), preferably natural raw coal composite raw material (40-50) (containing 10-25% of low-value coal gangue, coal slurry and middlings), modified plant optimal material (45-58), environmental-protection cleaning agent (5-7), energy convergence accelerating agent (6-12) and mixed double-polar binder (4-6); or natural raw coal composite raw material (45-55) (containing 26-40% of low-value coal gangue, coal slurry and middlings), modified plant optimal material (40-50), environmental-protection cleaning agent (5-7), energy convergence accelerating agent (6-15) and mixed double-polar binder (4-6).
