Study on the Preparation of Oil-Coal-Water Slurry

摘要

This paper presented a method of a new kind of triplex mixture system of oil-water-coal slurry preparation. Triplex synfuel containing gasoline, water and coal was prepared using nonionic surfactant. Tween 80 was used as emulsifying agent. The ratio of water, gasoline and coal was optimized. The optimum prescription of oil-water-coal slurry was obtained by means of orthogonal experiment. Results showed that stable triplex mixture systems were prepared with the ratio of the components of coal (C) to water (W) to oil (O) by weight was C:W:O=45%:30%:25% when 0.2% Tween 80 were added into the system. Rheological properties of oil-water-coal slurry were also investigated.
