| Popis: | This communication reports the current progress in thermal analysis studies on oil sludge pyrolysis. The pyrolysis behaviors of three different oil sludge samples were studied and compared using the results of thermogravimetry (TG) and differential thermogravimetry (DTG) analysis. Then, the evaporation stage of the pyrolysis process was analyzed by comparing the peak distribution in the DTG curves of the oil sludge samples with that obtained for artificial oil sludge. The relationship between the DTG peak distribution and the surface properties of the oil sludge particles was determined. As a complement to our previous study, the active stage of oil sludge ash additive was determined based on the results obtained from the pyrolysis of oil sludge with and without the addition of oil sludge ash. The kinetic parameters were calculated using the iso-conversional differential method, the integral method, and the Kissinger method. The results of this study provide reference values for practical engineering applications. |
