Abstract: Kinetic parameters of kerogen pyrolysis have been widely used in basin modelling. Because the de-tection of gas products is more difficult than that of liquid products in thermal simulation experiments,the study of natural gas generation is random. The combination of TG( thermogravimetric)analysis with Fourier transform infrared(FTIR) spec-troscopy analysis was used to analyze different coal macerals and detect the pyrolysis products. The powdered samples were grogerssively heatedcatra to of 25℃/minute) and weighted in theT G A. A carrier gas transported the effluent through a multipass gas cell for continuos analysis by FTIRSelected infrared absorption bands were used to detect different compounds. Data were captured foraliphatics, aromatics, cardon dioxide and methane. The analytical results indicated that different coal macerals have different characters in pyrolysis. Hydrocarbon generation can be modelled by assuming that a number of parallel first grder reactions control the thermal decomposition of kerogen.
