Embodiment 1
[0029] Embodiment 1: A super wear-resistant carbon black with high structure and low heat generation, which uses a mixture of anthracene oil and coal tar with a weight ratio of 8.5:1.5 as raw material oil, natural gas as fuel, no additives, and super wear-resistant carbon black It is prepared by the production process of grinding furnace and black furnace method; the raw material oil processing capacity ranges from 4000 to 4300kg / h. The water content of various oil products in the raw oil must be less than 2%, the density should be between 1.09-1.21g / ml, and the oil yield should not be less than 50%.
Embodiment 2
[0030] Embodiment 2: produce the super wear-resistant carbon black of the high structure low heat generation described in embodiment 1 with super wear-resistant furnace black furnace method, the concrete steps of production technology are as follows:
[0031] (1) The air compressed to 170Kpa is preheated to 750°C by the air preheater, and sent to the air distribution room of the reaction furnace through the hot air pipeline;
[0032] (2) Send the fuel into the combustion chamber of the reaction furnace, mix and burn with the hot air sent from the air distribution chamber above, and control the temperature at 1918°C. After the raw oil is preheated to 200°C by the raw oil preheater, it is sprayed into the throat section of the reaction furnace, atomized and sheared, and cracked for 10 milliseconds in the reaction section of the reaction furnace (the temperature of the reaction section is 1650 ℃), producing carbon black smoke;
[0033] (3) The carbon black flue gas is quenched o...
Embodiment 3
[0036] Embodiment 3: A super wear-resistant carbon black with high structure and low heat generation, which uses a mixture of anthracene oil and coal tar with a weight ratio of 9:1 as raw material oil, natural gas as fuel, no additives, and super-resistant carbon black It is prepared by the production process of grinding furnace and black furnace method; the processing capacity of raw material oil ranges from 3900 to 4200kg / h. The water content of various oil products in the raw oil must be less than 2%, the density should be between 1.09-1.21g / ml, and the oil yield should not be less than 50%.
