In this paper, the catalytic pyrolysis of Jimsar oil shale was studied using CoCl2 center dot 6H(2)O as a catalyst. The thermogravimetric analysis (TGA) was carried out on oil shale samples with the catalyst added. The kinetic analysis of the pyrolysis reaction of each sample was performed using the main curve method and several model-free methods. The results showed that CoCl2 center dot 6H(2)O could not only reduce the average activation energy of oil shale pyrolysis from 216 kJ/mol to 163 kJ/mol, but also decrease the pyrolysis temperature by about 100 degrees C.
