Abstract
The invention provides a hot-cracking-method carbon black production process assisted by hydrogen-enriched gas. In a production process of semi-reinforced carbon black, a hot cracking method is used for producing the hydrogen-enriched gas to replace part of the natural gas to be used as fuel and combustion air to enter a combustion room (8) to combust; after the gas is sufficiently combusted in a hearth (3), high-temperature gas of 1450-1800 DEG C is generated and is jetted at a speed of 100-200 m/s to be mixed with raw material natural gas; under the effect of a high-temperature and high-speed air flow, the raw material natural gas and the high-temperature gas are rapidly mixed and cracked; then, the mixture of the raw material natural gas and the high-temperature gas enters a flue reaction room (12) to be continually cracked; and finally, cooling water is quenched to stop a cracking reaction to obtain carbon black. The hydrogen-enriched gas is sufficiently utilized as a lower calorific value fuel resource, the reaction efficiency is high and the process is simple; and less room-temperature gas is discharged, a combustion speed is fast and the output can be obviously improved.
