The pyrolysis kinetics were investigated with the en- dothermal peaks in their DTA curves using integral method and differerntial method on an overall first order kinetic model. The kinetic parameters were calculated. It was shown that the pyrolysis of kerogen was retarded by pres- sure, and some effects of pressure on the pyrolysis kinetics were also inves- tigated. Furthermore, a pressure factor f was proposed, and a new pressure kinetic model was established. Results indicate a fair agreement between experimental and calculated data by using the suggested model.

Pyrolysis experiments on single Huangxian lignite lump(20-60mm in diameter) were carried out in a thermogravimetric analyzer for large samples at the constant heating rate of 2℃/min. The experimental data of weight loss and intralump temperature ditsribution were obtained. The effect of sample size on pyrolysis reactien has been investigated. A kinetic model which takes the pyrolysis reaction together with the internal temperature gradient into account was successfully developed. The results indicated that the apparent activation energy is about 110kJ/mol and that maximum temperature difference is about 100℃ for sample size of 60mm.
