weight ratio the spectra for the 20 vol glycerol sample show an absorbance at 633 nm of 1 71 this sample was subsequently analyzed by a laser droplet sizer that demonstrated a resulting droplet size distribution spanning 1 4 microns is shown in fig2 demonstrated emulsion creation with intermediate fuel oil 180 99 pure glycerin marine gas oil span 80 and span 85 surfactants in this experiment 70 ml of 99 pure glycerin was placed in a 300 ml wide mouth pyrex u00ae bottle added onto of the glycerin was 60 ml of intermediate fuel oil 180 25 ml of marine gas oil 3 ml of span 80 surfactant and 2 ml of span 85 surfactant for a total sample volume of 160 ml the mixture was place in a water bath and heated to a uniform temperature of 70 u00b0 c the mixture was then vigorously agitated by hand to create a uniform appearing mixture the mixture was immediately emulsified using an ultrasonic processor which utilized a u00bd u2033 horn operated at a frequency of 20 khz with a power output of 75 watts for 20 seconds for a total power output of 1 523 joules the resulting emulsion was dark brown in color and uniform the emulsion remained homogeneous in nature for over 168 hours at room temperature this homogeneous mixture is shown in fig6 in the a free glycerol layer is clearly present at the bottom with heavy fuel oil 180 and surfactant on top after processing b the glcycerol emulsion remains homogeneous for extended periods of time demonstrated 24 hour emulsion homogeneity using ultra low sulfur diesel reagent glycerol water and technical grade mono di tri glycerides in this experiment 100 ml of ultra low sulfur diesel fuel 15 ppm sulfur concentration was placed in a.
