45.褐炭ブリケットの吸水崩壊に関する研究

抄録

The factors that determine the easiness of disintegration of brown coal briquttes by sorption of water was investigated by employing some surface treatment toward brown coal particles, steam treatment, acid washing, Ca-exchange, and heat treatment. Increase in COOH brought by steam treatment rather than decrease in cation by acid washing was found to show an excellent resistance against the disintegration. Heat treatment at 200℃ was optimum by giving a good resistance comparable to steam treatment.
