Kinetics of the coke shrinkage process during calcination

01/01/1980· The isothermal dimensional analysis is adapted to the coke shrinkage process by placing a coke sample into a dilatometer and measuring the expansion and contraction of the coke as a function of temperature and time. The apparent activation energy of the coke shrinkage process is computed from the experimental deformation rate data.

Process for calcining coke Koa Oil Company, Limited

As is apparent from the foregoing, the process for calcining coke according to the present invention has the following advantages. (1) By using three or more heating furnaces, the respective stages of the coke calcination can be controlled independently from each other and the optimum conditions for producing high-grade coke can be realized. (2) By ensuring complete control of the combustion

Production and Application of Calcined Coke In Rotary

Keywords—Calcination, coke, rotary Kiln, petroleum . I. INTRODUCTION ALCINED Petroleum Coke (CPC) is manufactured from Raw Petroleum Coke (RPC) by the process known as high temperature pyrolysis. Several papers have been published over the last 5 years comparing rotary kiln calciners to shaft calciners [1,2,3,4]. Shaft calciners are common in China but there are very few operating outside

Influence of Coke Calcining Level on Anode Real Density

measures to control coke calcination levels. They are also measured routinely on anode core samples as a means of tracking anode baking levels. Many anode producers target anode RD levels which are at least 0.02 g/cm3 higher than the calcined petroleum coke (CPC) RD to minimize differential reactivity between the CPC and binder derived carbon. Depending on the calcining process parameters and

What is Calcining? (with pictures) wiseGEEK

06/11/2020· Calcining, also called calcination, is an industrial process that uses very high temperatures, often between 1,400-1,800 degrees Fahrenheit (800-1,000 degrees Celsius) or higher, to change the physical and chemical properties of various solid materials, such as minerals, metals, and ore.The origin of the term comes from one of the oldest and most common calcining processes:
