摘要

Non-isothermal and isothermal analysis of Tarfaya's oil shale residual carbon has been studied under a reactive atmosphere (mixture of N_2 and H_2O). The non-isothermal results show that the reactive atmosphere enhances the decomposition of the residual carbon much more than nitrogen and that this decomposition depends on the heating rate used to generate this residual carbon. The kinetics analysis indicate the possibility of two consecutive first order reactions. The isothermal weight change determinations was carried out under the same atmosphere at different temperatures and reveals also the presence of two consecutive first order decomposition reactions.
