Eluciation of hydrogen mobility in coal using a tritium tracer method. 1. Hydrogen exchange reaction of coal with tritiated water

摘要

The hydrogen exchange of coals with water was investigated using a tritium tracer method to estimate the mobility of hydrogen in coals. The reactions at several temperatures between 50 and 300 deg.C were carried out using a glass batch reactor and a pulse flow reactor, respectively. At lower temperatures, the ratio of hydrogen exchange of coal with water increased with a decrease In rank of coals and tended to change with respect to the content of functional groups such as Hydroxyl group, thiol, amino groups, and carboxylic acid in coal.
