Canada has considerable coal resources, which are produced by conventional means. Oxidative coal dissolution approaches coal production in a different way. Oxidative coal dissolution is the conversion of coal using air at mild conditions to produce mainly water-soluble products. This approach to coal conversion has the potential to be applied to subsurface recovery of marginal coal deposits without mining. The dissolved coal produced by oxidative coal dissolution is substantially free of mineral matter. A second step is needed for the upgrading of the oxidative coal dissolution product, such as decarboxylation. There is also the possibility that the product can be upgraded to higher-valued materials. An investigation of both oxidative coal dissolution and the upgrading of the dissolution products will be undertaken.

加拿大有相当大的煤炭资源，这些资源是用常规方法生产的。煤的氧化溶蚀作用以一种不同的方式接近煤的生产。煤的氧化溶解是煤在温和条件下利用空气进行转化，主要生产水溶性产物。这种煤转化方法有可能应用于不开采的边缘煤层的地下开采。氧化煤溶解产生的溶解煤基本上不含矿物质。第二步是煤氧化溶解产物的升级，如脱羧。该产品也有可能升级为更高价值的材料。对煤的氧化溶解和溶解产物的改造进行了研究。
