Title:
REACTOR FOR THE PRODUCTION OF CARBON BLACK
Document Type and Number:
WIPO Patent Application WO/1999/051334
Kind Code:
A1
Abstract:
The present invention relates to a reactor for producing carbon black in which the particles have a size of between 110 and 600 Å. This reactor comprises the following members connected in series: a combustion chamber with systems for burning the fuel together with air; a multiple-channel mixing nozzle having a flow section with a global surface area of between 0.036 and 0.36 m as the ratio between a channel diameter (d¿c?) and the diameter at the global surface area of the flow section in said mixing nozzle (d¿ef?) ranges from 0.35 to 0.72, said nozzle being provided with raw-material injectors; and a reaction chamber comprising systems for cooling down the gaseous carbon-black-containing products. This reactor has a large unitary rate (up to 5000 kg/h of raw material) and is capable of producing carbon-black at a particle coalescence rate in the apparatus that ranges from 0.03 to 0.09. The use of the carbon black thus obtained in vulcanised rubber mixtures increases the physical and mechanical indices.
