calcination of petroleum coke high melting point

Modifiion of coke by different additives to improve

Modifiion of coke by different additives to improve anode properties. (calcined petroleum coke, butts and recycled anodes) and coal tar pitch. The poor wettability of coke modified by the high melting point additive (A3 and A4) might be due to non-homogeneous distribution of the additive in the coke matrix.

Calcination | definition of calcination by Medical …

calcination The process of heating a solid (e.g., an ore) in air below its melting point to effect thermal decomposition, phase transition or remove volatiles, thereby changing the original solid into something else—e.g., heating calcium carbonate to release CO2 gas and form calcium oxide.

EP0018064A1 - Method and apparatus for calcining …

Particulate carbonaceous material, for example delayed petroleum coke, is calcined in an internally-fired vertical shaft kiln (10). A downwardly-moving bed of green coke is preheated in the top of the kiln by rising coustion gases, then heat soaked at calcining temperatures in the intermediate section of the kiln, and finally cooled by recycle gas moving upwardly from the lower part of the kiln.

Calcination - Infogalactic: the planetary knowledge core

2018-8-19 · The calcination process normally takes place at temperatures below the melting point of the product materials. Calcination is not the same process as roasting. In roasting, more complex gas–solid reactions take place between the furnace atmosphere and the solids. Calcination takes place inside equipment called calciners.

Annealing, Sintering and Calcining Processes - CM …

Calcination is one of the most common processes used in the ceramics industry among many others. The most common appliion for Calcining is the decomposition of calcium carbonate to calcium oxide and carbon dioxide, in order to create cement. The product of calcination is usually referred to as “calcine,” regardless of the actual minerals undergoing thermal treatment.
