A comprehensive investigation ot the second weight loss step for Huangxian oil shale was performed by comparison of IR spectra of semicoke obtained at various end temperatures of pyrolysis and shale sample treated with MCI and in combination with the kinetic parameters of the second pyrolysis and other evidences.These results verified that the second weight loss step is caused mainly by pyrolysis of dolomite and calcite in oil shale. Thermogravimetric data in the second weight loss step were fitted satisfactorily...

The calculation of the non- isothermal decomposition kinetic parameters for ephedrini hydrochloridum and ribavirinum was processd by this method,and non- isothermal decomposition kinetic function was determined,which showed that the method was sound and feasible.Meanwhile,the reason why sole TG curve was coped with several model functions was studied.The thermal decomposition kinetic function obtained is solely and reliable by combining single and mutile- heating rate method.
