Embodiment 1
[0033] The raw material oil is a mixture of coal tar and anthracene oil, and the ratio of coal tar and anthracene oil in the raw material oil is: weight ratio 8:2; the moisture content of the raw material oil is less than 4%, and the density is 1.15g / ml. The oil yield is greater than 65%.
[0034] The additive is potassium carbonate.
[0035] PSL-203 series carbon black products are produced by a new process of furnace method pigment carbon black production process, the production process is as follows:
[0036] 6) The air is compressed by the Roots blower to a pressure of 0.032Mpa, then passes through the low-temperature air preheater, the medium-temperature air preheater and the high-temperature air preheater in sequence, and is heated to 600°C before being sent into the combustion chamber;
[0037] 7) Send fuel oil and additives into the combustion chamber and mix with hot air for combustion. The temperature is controlled at 1500. The hot smoke generated by combustion ente...
