Abstract
The purpose of this investigation is to clarify the influence of micropore volume of coke on reaction of coke and CO2 gas.
We change the micropore volume by deashing treatment and we study the reaction of coke and CO2 in the range of 950°C to 1400°C.
The findings obtained are as follows:
1) The factor of coke quality for CO2 reaction of coke differ by reaction temperature.
(1) At 950°C, contribution of micropore volume is about 30% and contribution of content of optical anisotropic texture is about 70%.
(2) At 1200°C, the influence of content of optical anisotropic texture is gone for the reaction rate and micropore volume of coke decides the reaction rate.
(3) At 1400°C, reaction rate is independent of coke quality.
2) Reactivity in the range of 1000°C to about 1300°C can be dropped by the decrease of micropore volume.
3) As a result, further study is necessary the decrease of micropore volume as the method of decrease of coke reactivity at high temperature.
