The thermal decomposition of kerogen in a Colorado shale was studied in a TGA‐type apparatus in which the temperature was first increased at a constant rate and then held constant at a plateau value. Data were obtaiend at plateau temperatures from about 573 to 703 K and at 101.3 kPa. The objective of the research was to determine the influence of transport effects on the observed rate of decomposition. The results show that, for the shale studied, transport of heat and mass influenced the rate, if the particle size was greater than about 0.4 × 10 −3 m and if more than two to three layers of particles were placed in the weighing basket.
