CALCINED DOLOMITE - CALCINOR. Minerales industriales

Calcined dolomite is a material that plays an important role in the steel sector, both for its purifying action and for the protection of refractory linings. Calcium and magnesium oxide or calcined dolomite are obtained from dolomitic minerals such as calcium carbonate and magnesium (Ca Mg (CO3) 2, through the calcination process .

Calcined Dolomite: An Efficient and Recyclable Catalyst ...

13/12/2018  Natural dolomite exhibited lowest surface area; while after calcination, the calcined dolomite showed larger pore volume and higher surface area compared with those of natural dolomite. Among them, dolomite-700 °C exhibited the highest surface area and the largest pore volume. This was because the mesporous pores were formed through the decomposion of dolomite during the calcination

A review of dolomite catalyst for biomass gasification tar ...

01/05/2020  Cho et al. reported 73% tar reduction with calcined dolomite in comparison to silica sand for the air gasification of mixed plastic wastes in a two-stage gasifier. Dolomites become chemically active after being calcined at a temperature above 900 °C. The calcined dolomites are generally referred to as cracking catalysts with formula CaO.MgO.

Effect of natural dolomite calcination temperature on ...

01/05/2013  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.

Understanding the hydration of dolomite in cementitious ...

01/06/2018  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. The presence of dolomite renders limestone unsuitable for the production of clinker, as the dolomite ...

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.
