Thermal decomposition of limestone in a fluidized

Particles of limestone of 16 to 28 and 60 to 100 mesh sizes were decomposed in a fluidized bed. A mathematical model for the thermal decomposition was proposed comprising the thermal decomposition at the interface within particles and the related heat and mass transfer steps.

A Kinetic Study of Thermal Decomposition of

2012-4-27  In all samples, limestone decomposition starts with dolomite dissociation, followed by calcite decomposition. Rather than particle size, limestone texture, and dolomite content seem to be the most important factors controlling the starting temperature of calcination and its kinetic behavior.

Study of Limestone Thermal Decomposition in

2012-8-18  In this article, experiments have been done to investigate the behavior and mechanism of limestone thermal decomposition by a thermogravimetric analyser (TGA). It was observed that the limestone specialities of physical properties, pore structure, impurities categories and content have an important influence on the decomposition properties.

2021-3-10  Most metal carbonates you will come across will break down on strong heating (thermal decomposition) to give a metal oxide and carbon dioxide gas. When limestone is heated in a kiln at over 825-900 o C, it breaks down into quicklime (calcium oxide) and carbon dioxide. Both are useful products.

2021-3-10  Note on heating other carbonates you get a similar thermal decomposition. Other carbonates show a similar thermal decomposition to calcium carbonate e.g. using the simple apparatus illustrated below. Unlike limestone, some carbonates can be decomposed in the school/college laboratory using a bunsen burner and pyrex test/boiling tube.

Thermal decomposition of calcium carbonate

Calcium carbonate is strongly heated until it undergoes thermal decomposition to form calcium oxide and carbon dioxide. The calcium oxide (unslaked lime) is dissolved in water to form calcium hydroxide (limewater). Bubbling carbon dioxide through this forms a milky suspension of calcium carbonate. This experiment can be carried out conveniently ...
