Abstract:
     The invention relates to a new liq. fuel,i.e. the pulverized coal is dispersed in water at high coal concn,and this can be used as boiler fuel instead of fuel-oil.This fuel can be transportted through pipeline.The invention uses hamic acid or sulphonic deriv. derived from peat,weathered coal or lignite as additive for prepareing high concn. aq. coal slurry contg.solids of above 55%.The additive is cheap and abundant in natural resources.The additive has molecular wt. less than 50,000, the concn. of the additive is about 0.01-10%(by wt.) of coal. Either used solely or used together with other additives, the invention can obtain good ag. coal slurry of low viscosity and high stability.
