摘　　要：用二连脱油沥青和尤利卡沥青混合物作原料,按双指标控制的自然粒度分布粉碎,分段加入水和结构相似、相对分子质量接近的分散剂,可以制备一种清洁化的液体代用燃料。该燃料具有高沥青含量(大于65%),低粘度(小于100 mPa·s,100 r/s),泵送性能和流动性好,稳定性满足工业要求,燃烧效率高,便于组织燃烧,燃烧烟气有害物含量低等优点。采用不同软化点的硬沥青复合制成水浆,对解决高软化点沥青的出路问题、增强溶剂脱沥青和尤利卡热裂化工艺的竞争力以及解决沥青水浆工业化的难题都具有重要意义。The mixture of Erlian deoiled asphalt and Eureka bitumen was grinded according to the nature particle size distribution controlled by double indexes, the dispersant having similar structure and molecular weight, and water were added into the mixture stage by stage for preparing a clean liquid fuel. The prepared fuel had high bitumen content (>65%), low viscosity (<100mPa ·s, 100r/s), good fluidity and pumping performance, high combustion efficiency with low harmful components in flue gas, and the stability could fulfill the industry demand. Preparation of slurry with various softening point hard bitumens could solve the way out of high softening point hard bitumens. The new process strengthened the competition force of solvent deasphlting and Eureka cracking process, and solved the problem of the commercialization of bitumen slurry.
