Production Of Fine Coke (Char)

The Circochar process, a spin-off of the Circofer technology, produces fine coke and a valuable fuel gas from fine-grained volatile coals. This fine coke production, also known as ‘charring’, is based on Outotec’s circulating fluidized bed (CFB) technology, which has been applied in over 150 commercial plants worldwide ranging from the calcinations of aluminum hydroxide and coal combustion, to the reduction of iron ore fines. Apart from fine coke, a fuel gas is created, whose gas quality can be adjusted to meet the requirements for power generation by adding steam or oxygen to the process.
