摘要：

The reaction rate of coke, wood charcoal and graphite with pure CO, were obtained at 1 173 and 1 373 K. The change in the reaction rate, specific surface area and micro pore size distribution with reaction degree were examined. The results are summarized as follows. (1) The specific surface area changes remarkably with reaction degree, while the reaction rate does not change so much. (2) The change in the specific surface area accords well to the change in the volume of smaller pores than 10(-8)m in diameter. (3) The reaction occurs exclusively on the surface of pores between 10(-8) to 10(-6) m in diameter. (4) The effective surface area for the reaction is from 0.064 to 0.25 of the total surface area.
