Three types of local Malaysian dolomites were characterized to investigate their suitability for use as tar-cracking catalysts in the biomass gasification process. The dolomites were calcined to examine the effect of the calcination process on dolomite's catalytic activity and properties. The modifications undergone by dolomites consequent to thermal treatment were investigated using various ...
Dec 05, 2017· Calcined Dolomite or FluxDolomite is the name given to the quicklime formed from calcininga natural dolomitic limestone that contains nearly an equal molar weight percentage of calcium oxide to magnesium oxide.
A method for calcining dolomite in which the pressure of carbon dioxide is controlled is described. Less than ½ of one per cent of lime is liberated. Material was calcined in ton lots using external heating. Two types of retort were used: wrought iron and fire clay.
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.
applications of dolomite depend on its physicochemical, structural, and thermodynamic properties. Knowledge of kinetics thermal decomposition of min-erals is very important for the calcination process in industrial production. The kinetics of the thermal decom-position of dolomite has been studied owing to .
The decomposition of dolomite into CaO and MgO was performed at 1073 K in vacuum and at 1273 K in an Ar atmosphere. The dolomite calcined in vacuum was found to have a higher specific surface area and a higher micropore volume when compared to the dolomite calcined in the Ar atmosphere. These pyrolysis products of dolomite were reacted with CO2 at 673 K for 21.6 ks.
Natural dolomite was calcined at different temperatures in the range 873-1373K and characterized by X-ray diffraction, X-ray photoelectron spectroscopy, scanning electron microscopy, and N 2 adsorption/desorption isotherm. The calcination temperature had considerable effect on the surface chemical composition, crystallinity, and basicity of CO 2 gas sorption of each component in the .
Calcination of dolomite involves heating the raw material at sufficient temperature in order to release the carbon dioxide from its carbonate minerals. This process is commonly conducted in a rotary kiln. There have been a number of calcination studies in a laboratory scale, but the study of dolomite calcination in a larger scale is very scarce.
