Rotary Kiln Reactor For Char Activation

The activation process is strongly endo- thermic and involves gasification of the carbona- ceous char by oxidation with either water vapor or carbon dioxide in the temperature range of 1073 - 1373 K. This process is carried out in either directly or indirectly fired activators, such as rotary kilns.
We have 40 years of experience in mechanical manufacturing and provide you with the most sophisticated equipments.

Rotary Kiln Slow Pyrolysis For Syngas And Char Production ...

Rotary Kiln Slow Pyrolysis For Syngas And Char Production ...

Jan 05, 2007 A microscale electrically heated rotary kiln for slow pyrolysis of biomass and waste was designed and built at the University of Perugia. The reactor is connected to a wet scrubbing section, for tar removal, and to a monitored combustion chamber to evaluate the lower heating value of the syngas.

Application: Activation

Application: Activation

The solid residues of a waste pyrolysis process often contain a lot of chemical bound energy. This energy could be used by a so called Carbon Recovery Unit (CRU). The gasification takes place in a rotary kiln. The ratio of the feeded air and steam has to be balanced to heat up the char to approximately 900 C.
