Abstract
Immature organic matter(peat) were pyrolysized at temperatures ranging from 200℃ to 400℃ under high pressure ranging from 0.1 to 2 GPa in a closed system. As the index of maturation, vitrinite reflectance (Ro) of samples was measured. The results display that Ro value of samples tends to rise when temperature increases under constant pressure and the Ro value decreases when pressure increases under constant pressure. These results indicate that pressure is one of factors that influence the maturation of organic matter as important as temperature do, and the pressure can retard the thermal evolution of organic matter. The function of pressure has its interior kinetic principle. The role of pressure in organic maturation process of organic matter can't benig nored as suggested by results of experiment and fact of Geology. It has important theoretical and practical significance on studying the function and influence of pressure by means of pyrolysis
