2019-5-24  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.

Understanding the hydration of dolomite in

2018-6-1  Formation of dolomite can occur via two possible mechanisms – i) direct precipitation from solution to form primary dolomite, and ii) dolomitization process in which calcite undergoes dissolution supplying the Ca 2+ ions followed by the precipitation of dolomite from a solution rich in Mg 2+ ions [1,2]. Therefore, it is not uncommon to observe dolomite coexisting with calcite.

What is the difference between dolomite and calcined

Dolomite is a mixture of calcium and magnesium carbonates, i.e., CaMg (CO3)2. When you calcine this salt by heating to high temperature, it decomposes to CaO and MgO and CO2 gas is released. Hope...

Effect of natural dolomite calcination temperature on ...

2013-5-1  Natural dolomite was calcined at 700–900 °C under air and an Ar gas flow atmosphere to characterize its sorbency potential for borate. A sequential decarbonation occurred with increase in calcination temperature, that is, transformation of CaMg (CO 3) 2 to MgO and CaCO 3 up to 700 °C and CaCO 3 to CaO from 700 to 900 °C.
