Excerpt from American Fuels, Vol. 2 of 2

Tests made with a number Of typical coals Of the United States gave an ash reduction varying from 30 to 75 per cent. Sul phur reduction was fairly good in the case Of anthracites, but low in the case Of bituminous coals. Combustible recovery was, with a few exceptions, better than 95 per cent. Results point to the desirability Of preliminary water concentration Of high-sulphur coals for removal Of pyrite before treatment by the Trent process. It has been found that grinding finer than 200-mesh does not give sufficiently greater ash reduction to pay for the increased cost Of finer pulverization.

Amalgamation of Hydrocarbons - The physical reaction involved in the formation Of the amalgam has been found to take place between most Of the liquid hydrocarbons and the solid bituminous or carbonaceous minerals. The results attained with various Oils, together with the general principles involved in the process, are summarized as follows in the report.
