PROCESS FOR THEMANUFACTURE OF LOW-ASH ELECTRICALLY CONDUCTIVE CARBON BLACK AND AN APPARATUS FOR MAKING THE SAME

摘要

In the process without supporting flame and quenching, the hydrocarbons are heated under pressure without segregation to at least 120 DEG C, and the oxygen gas is heated to a temperature of at least 150 DEG C above the temperature of the fuel. A mean residence time of at least 10 seconds is maintained in the reaction. The carbon black formed in the reactor is then cooled in stages to the filtration temperature. The equipment for carrying out the process contains at least one heat exchanger for indirect cooling of the carbon black product.
