Calcined Dolomite, Magnesite, and Calcite for Cleaning Hot ...

Calcined dolomites, limestones, and magnesites are active and inexpensive solids for cleaning raw hot gas from biomass gasifiers with steam. The variations of their activities with time-on-stream are studied here. Simultaneous coke formation and coke elimination by steam gasification increases the life of these "naturally occurring" catalysts under some circumstances.

DF2014:Dolomite - Dwarf Fortress Wiki

Dolomite is a white medium-value and economic type of sedimentary stone that forms entire layers. It is also a flux stone, meaning it can be used in the production of pig iron and steel.Additionally, it is magma safe, with an extremely high melting point of 16507 °U, in fact, the highest melting point of all common stones, barring raw adamantine (and, because it cannot be melted, slade 1).
