Abstract

Extensive studies have been carried out on the genetic chemical reaction of coals by many famous researchers. Some of the previous studies are as follows: H. Potonei[1] initiated the study of coalification. F. Fischer, et. al.[2] supported the origin of lignin theory. F. Bergins[3], Erasmus[4] and R. V. Wheeler, et. al.[5] supported the cellulose theory. Tropsch[6], Berl and Schmit[7], Horn and Sustsmann[8] and Fuch and Horn[9] developed the systematic investigation on artificial coalification. Berl and Schmidt[10] experiments on coalification were checked and confirmed by Schuhmacher and Van Krevelen[11]. Two researches on this topic were studied in our country. W. Funasaka and C. Yokokawa[12] discussed the relationship between the genetic origin of coal and its chemical properties at atmospheric conditions by artificial coalification experiments. T. Yamazaki and R. Abe[13] reported the experimental results of the gas evolutions from raw coal during the artificial coalification process following the procedure presented by C. Yakakawa.
