In the author's 3rd report, the reformative result of the pyrolysis reaction, to reduce oxygen contents in low-rank coal by autoclave, was submitted.
In this report, it has been discussed that about brown coal, above all low-rank one like lignite, the carboxyl group, to cause high moisture contents and to promote spontaneous conbustion, in the reformed coal, is remarkably reduced in comparison with one in the raw coal, by the reaction to be based on the same method in 3rd report.
