Abstract:
The production of carbon black by the pyrolytic decomposition of a hydrocarbon feed within a reactor having an axial zone, a precombustion zone, a combustion zone, and a reaction zone wherein flow of a portion of the reactants is established between the axial zone and the precombustion zone through at least one conduit connecting said zones.
Abstract:
A MATERIAL WHICH ACTS BOTH AS A PELLETING AGENT AND A DISPERSANT FOR CARBON BLACK IN RUBBER WHICH COMPRISES A POLYETHOXYLATED AMINE CONTAINED IN CARBON BLACK IN THE AMOUNT OF ABOUT 0.1 TO ABOUT 10%.
Abstract:
A SAMPLE OF THE GAS INCLUDED IN CARBON BLACK SMOKE IS OBTAINED BY DRAWING THE GAS SAMPLE THROUGH A REVERSIBLEFLOW FILTER AND A FIRST AND SECOND COOLER. A COMPRESSOR, WHICH DRAWS THE GAS SAMPLE INTO THE APPARATUS, IS CONNECTED BETWEEN THE FIRST AND SECOND COOLERS AND HAS A CONDUIT ROUTED BACK TO THE FILTER. THUS, A PORTION OF THE SAMPLE GASES WITHDRAWN THROUGH THE FILTER, FIRST COOLER AND
COMPRESSOR IS REINTRODUCABLE TO THE FILTER FOR CLEANING SOLIDS FROM THE FILTER.
Abstract:
A method of pelleting particulate solids employing a pelleter having separate upper and lower jackets by means of which the upper and lower sections of the pelleter can be maintained at different operating temperatures. In one embodiment of the invention, the wall of the pelleter which comprises the inner wall of the jackets is adapted with apertures through which that material introduced into the jacket to heat the wall of the pelleter is brought into contact with the material adhering to the inner wall of the pelleter to remove the adhering material therefrom.
Abstract:
A carbon black pelleting agent which acts as a pelleting agent and which acts to disperse the carbon black in rubber which comprises an aqueous solution of a polyethyoxylated fatty acid.
