石炭の急速熱分解における固相からの揮発分ならびに硫黄の放出速度

抄録

Kinetic parameters were determined for the release rates of volatile matter and sulfur from coals at temperatures of 1120K to 1550K by using a free-fall pyrolyzer which enabled coal particles to be heated at the rate of 2 × 10⁴Ks^-1. The release rate of volatile matter increased with the increase of heating rate while each coal showed a different dependency of ultimate volatile yield on the heating rate and final temperature. The desulfurization extents of organic sulfur were larger than the ultimate volatile yields. The release rate of organic sulfur increased with the increase in heating rate.
