Catalyst Complexed Carbon Slurry Fuel Development.
Abstract
Catalyzed carbon blacks and a control sample were prepared for the purpose of evaluating the effectiveness of the catalyst in the improvement of carbon slurry combustion. Two batches (100 pounds each) of carbon black containing 0.2 and 0.99 percent iron catalyst highly dispersed within the carbon structure were produced. Each carbon black was thoroughly characterized by the standard methods used in the carbon black industry. Slurries (five gallons each) were prepared using state-of-the-art dispersing technology at a carbon black loading of 25 weight percent, with JP-10 as the liquid carrier. With the objective of evaluating the effect of carbon black particle size on the combustion efficiency of carbon slurries, four commercial carbon blacks representing a wide particle size range were selected and slurries were prepared. The carbon blacks selected and their average calculated particle diameter (in nanometers) were: United N219 (30 nm), United N660 (56 nm), United SL-90 (103 nm), and Statex MT (300 nm). Slurries (five gallons each) were prepared with each carbon black at a loading of 25 weight percent with JP-10 as the liquid carrier. In addition, slurries containing 65 weight percent Statex MT and 60 weight percent United SL-90 were also prepared in five gallon quantities. Each carbon slurry fuel was characterized by measurement of the viscosity, density, net heat of combustion, flash point, and stability to centrifugation (900g for 30 minutes). The viscosity of each slurry was measured at 0 C, 25 C and 40 C over a wide range of shear rates.
