METHOD OF OBTAINING CARBON BLACK Russian patent published in 2008 - IPC C09C1/52 

FIELD: chemistry.

SUBSTANCE: invention can be used for obtaining carbon black from natural gas. The method of obtaining carbon black involves supplying fuel and an oxidising agent to the combustion zone, and a turbulent stream of hydrocarbon gases to the cylindrical reaction chamber, with their subsequent decomposition into soot and hydrogen. Part of the cylindrical reaction chamber is made from high-melting porous material. The soot accumulates on the inner surface of cylinder 2 and partially penetrates into the porous material. In the pore space there is accumulation of soot, resulting in lower permeability of the walls. Mechanical oscillations at the resonance frequency of the porous part of cylinder 2 can be stimulated in the reaction chamber using vibrators 9 and 10. This will reduce cohesion of soot on the surface of the pores. In this way, there is separation of the soot and its deposition into volume 8. Hydrogen passes through the pores to combustion chamber 3 and extra heat energy is released from burning. That energy is used to heat cylinder 2.

EFFECT: lowering of specific energy consumption and specific metal quantity of the basic equipment.
