The adsorption by coals from mixtures of n-alkane and benzene was investigated from the points of carbon contents of coals and of chain-length of n-alkane. As a result, in n-hexane and benzene, n-hexane was adsorbed preferentially by coals with carbon contents from 62% to 75%, while preferential adsorption of benzene occurred on coals with carbon content from 80% to 90%. In coal with carbon content of 93%, n-hexane was again adsorbed preferentially.
The effect of chain-length of n-alkane on adsorption was also examined. The preferential adsorption of n-alkane was dependent on chain-length of n-alkane and coals with different carbon contents. Particularly, in the coal with carbon content of 93%, preferential adsorption of n-alkane was decreased with increasing chain-length of n-alkane.
