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.
Jun 28, 2017 · Dolomite in iron and steel industry is normally used in three forms. These are (i) raw dolomite which is also the natural form of dolomite, (ii) calcined dolomite, and (iii) sintered dolomite. When dolomite is used as a fluxing material then it is used as either raw dolomite or calcined dolomite.
Get Pricemagnesium oxide or magnesium hydroxide are made by forming an intimate mixture of calcined dolomite and the stoichiometric amount of magnesium chloride (relative to the cao contents of the dolomite), then dehhydrating the mixture by heating it above 100*c., introducing the thus formed solid into water and recovering the magnesium oxide or -hydroxide residue by filtration.
