METHOD FOR PRODUCING GRANULATED ACTIVATED CARBON Russian patent published in 2017 - IPC C01B31/14 

Abstract RU 2637240 C1

FIELD: oil and gas industry.

SUBSTANCE: according to the invention, a binder is prepared on the basis of residual petroleum processing products, its dynamic viscosity is measured and mixed with coal dust of non-caking coal. The ratio of components is selected depending on rheological properties of coal compositions with binder and viscosity of binder used. The coal compositions with binder is moulded on a screw granulator. The obtained granules are aged, subjected to carbonization and activation in the medium of superheated steam.

EFFECT: method makes it possible to reduce the labour costs due to the possibility of selecting the optimal composition of the composition for granulation.
