23.褐炭液化反応の研究(14) : 褐炭中のClの反応挙動

抄録

Behavior of chlorine in Yallourn brown coal was investigated under reaction conditions during coal liquefaction with relation to the formation of NaCl, which is one of the compositions in preheater-scales. Although the 90% of chlorine (640ppm) in Yallourn coal was insoluble in water, it was found that most of the water-insoluble chlorine changed to be soluble in water during coal liquefaction at 350℃ for 10min. with iron catalyst. It seemed that NaCl was formed by the reaction from chlorine and sodium in Yallourn coal at the initial stage in liquefaction.
