ABSTRACT:
A novel process, and the compositions of matter formed thereby, wherein Group II-A metals, or compounds thereof, can be ion-exchanged onto coal, preferably a high rank coal, notably a subbituminous or bituminous coal, by soaking the coal in an alkali solution of a Group I-A metal compound sufficient to incorporate said metal compound, or cation portion thereof, into said coal to form ion-exchange sites, and ion-exchanging, and thereby replacing all or a portion, preferably a portion, of the Group I-A metal cations with said Group II-A metals. Enhanced gasification rates are achieved by gasification of the so-treated coal, or composition which contains both the Group I-A and Group II-A metals, as contrasted with a coal composition otherwise similar except that it contains an equal molar quantity of either a Group I-A metal or Group II-A metal, rather than both Group I-A and Group II-A metals.
