The pyrolysis of asphalt has been studied using thermogravimetric analysis at atmospheric pressure and with nitrogen as the ambient gas. The heating rates ranged from 50 or 80 o Cmin -1 to a final temperature of 650 o C. A two-stage first-order model is established to describe the pyrolysis of asphalt. In the model, the activation energy, E, is different for each stage,...
An investigation of the ignition delay time for oil–water emulsion with different additional more volatile liquid fuels as single droplets is conducted. The measurement is made by the suspended droplets. In the experiments, the ratio of n-dodecane, water and n-heptane (more volatile fuel) is as follows: 6:4:0, 5:4:1, 4:4:2, 3:4:3. The experimental and calculated results show that the ignition delay...
