文摘

Higher heating rates delay pyrolysis and extends it to match iron reduction point. Low volatile char contraction is not desirable for cooling part of TKDRI process. Swelling of high volatile coal is too much if it is aimed to be used in TKDRI. Cracks and open pores of char after devolatilization is desirable in TKDRI process. Structural ordering in addition to volatile percentage is affected by ash content.
