چکیده انگلیسی
There has been much interest in alternative fuels made from coal which is much more abundant than oil. The coal-oil-water slurry is a new type of oil-based synfuel composed of finely pulverized coal, oil and water. It has lower viscosity, lower ignition point and higher heating value than coal-water slurry. The preparation of stable water-in-oil (W/O) emulsion is critical for the success of production of stable coal-oil-water slurry. The present study was undertaken to experimentally investigate the effects of different process variables on emulsion stability. The emulsion was prepared using 100 ml colloid mill with sorbitan monooleate (SM) as emulsifier. The variables studied include emulsifier dosage, ratio of oil to water, stirring intensity, emulsifying temperature and mixing time. The results showed that the optimum process conditions are: emulsifier dosage, 0.5%; oil to water ratio, 1:1; stirring intensity, 2500 rpm; and mixing temperature, 30 °C.
