In Situ Capturing and Absorption of Sulfur Gases Formed during Thermal Treatment of South African Coals.

The objective of this study, the first of its kind on these specific South African low-sulfur coals, was to capture HS and SO produced under inert and oxidizing conditions from sulfur compounds present in the coals. The capturing agents were calcium and magnesium oxides formed during the transformation of calcite and dolomite. The effectiveness of two different scrubbing solutions (0.
