Coal slurry composition
专利汇可以提供Coal slurry composition专利检索，专利查询，专利分析的服务。并且PURPOSE: To provide a coal slurry compsn. which has excellent dispersion stability and does not form compacted hard cake on standing for many hours, by dispersing coal powder having a specified particle size distribution in water by using a specified anionic surfactant.
CONSTITUTION: 50W80wt% coal powder (i) having a particle size distribution such that particles having a particle size of 74μ or below account for 71W85wt% of the whole particles and the slope (tan α) of a straight line formed by a point representing wt% of particles having a particle size passing through 44μ and a point representing wt% of particles having a particle size passing through 74μ is 0.4W0.9 in a Rosin-Rammleris diagram, 0.01W5wt% surfactant (ii) selected from sulfonated naphthalene or creosote oil, salts thereof, aliph. aldehyde addition condensate thereof, and aliph. aldehyde addition condensate of sulfonic group-contg. aminotriazine or salts thereof, and 15W45wt% water (iii) are mixed together with stirring to form the titled compsn.
