Method of calcining coke in a rotary kiln

Definitions. This invention relates to the calcination of carbonaceous materials, particularly petroleum coke such as intended to provide carbon for making electrodes or the like. Calcining operations of this sort are commonly performed in a rotary kiln into which the green petroleum coke in suitable particulate form is fed at one end, for delivery of treated product at the other end.

SOLAR CALCINATION OF MINERALS

Of all the proposed concepts, the most used and studied are rotary kilns. After the first concept, proposed by Flamant, Meier et al. tested an open rotary kiln with a flow of 2.3 kg/h of 2–3 mm limestone particles. Calcination above 95% could be reached. In order to ensure a good particle mixing, high rotational speeds were required.

Rotary Kilns: Working Principles & History

In exploring the limestone rotary kiln further, the calcination process can be explained by looking at the chemical kinetics and thermodynamics involved. Limestone consists of calcium carbonate, which decomposes into lime and carbon dioxide gas. The calcination reaction is endothermic, requiring precise control of the kiln's heat input and ...

Modeling of Rotary Kilns and Application to Limestone …

This paper presents the one dimensional modeling of rotary kilns used for energy intensive production processes. Raw material is fed into an inclined rotating kiln and heated by counter current gas flow. Chemical reactions take place in the bed of raw material as well as in the gas phase. Heat and mass transfer between the bed and the gas phase are implemented. …
