Abstract
To clarify the differences in the reducing behavoirs according to the composition of pyrite cinders, the cinders were investigated as follows:
(1) Reduction efficiency on the reaction of CO gas and pitch coke.
(2) Measurement of the permeability (A. F. A) at various high temperatures.
(3) Compared with the surface conditions of cinder grains by electron microscopic examlnation.
(4) Measurement of the surface area by Bet process:
