The study of the oxidation or combustion of oil shale or coal is important because it is the basis of the exploitation process to obtain the energy to be converted This exploitation involves several physical phenomena such as heat transfer, matter transfer and others. The laws of matter transfer have been adopted The respective combustion of two national energy materials (Morocco), namely the Z4 layer of oil shale from the Tarfaya deposit and the coal from Jerada, was the subject of this study in an isothermal regime. First, we were interested in mentioning the average temperatures remarkable for this combustion which turned out to be slightly different, then we started a study of the combustion of parallelepipeds with variable dimensions of the two previous materials and we presented a simulated theoretical model by comparing it with the experimental results. This simulated model allowed us to discuss the reactivity of the two energetic materials. Combustion was followed in an isothermal regime using a muffle furnace from 400Â°C to 800Â°C for fine-grained samples (< 0.5 mm) and for grains. The noticeable loss of mass for oil shale at 500Â°C, and for coal at 600Â°C in the first instance. These remarkable temperatures were used to study the effect of parallelepiped dimensions, which have constant height (z = 2 mm) and square side surfaces (x = y = 2, 4, 6, 8, 10 mm). Several results and interpretations were noted when comparing the combustion of coal and oil shale.
