[0027] Examples:
[0028] The carbon black variety N326 is produced by the reactor of the present invention, coke oven gas is used as fuel, and the feedstock oil composed of 30% anthracene oil + 50% tar + 20% low temperature tar is sprayed into the throat section under atomized state for high temperature cracking production Carbon black, and 200Nm of coke oven gas is added to the front section of the pipe 3 / hr, carbon black smoke is collected into carbon black after being quenched. It can be seen from the table below that when a 40,000-ton reactor is used to produce N326 carbon black, the quality of the carbon black produced is obviously better than that of the carbon black produced in a 20,000-ton carbon black reactor. This is mainly reflected in the color strength of the product. (Tint). In terms of the compressed oil absorption value, the Tint value of the product produced by the 40,000 tons reactor is about 3% higher than the product produced by the 20,000 tons reactor. The ...
