OSTI ID:7233440
The chemical reactivity of chars from various ranks of coal with CO/sub 2/ has been studied using the diffusion cell technique which has been previously developed at BNL. Chars from the following coals were used: Montana lignite, Illinois No. 6 bituminous, and Pennsylvania anthracite. The reactivity peaks at a certain temperature and the peaking temperature can be correlated to the ash-melting temperature; this temperature varies widely from the range of 1100 to 1200/sup 0/C to 1500 to 1600/sup 0/C for the three coals. Results on the leached lignite and on the surface area measurements were also obtained and are used to discuss the effect of ash on the reactivity of char.
