Abstract

Methods for controlling the size and structure of the carbon black recombination of the reactor. Carbon black combustion by lowering the temperature but not hardening the heat. Of the part to flow out (Mixture of the combustion gas and the starting source from which the separation This is usually around 426.67 ° C (800 ° F) at intervals between about 0.0 s and about 0.002 s at the end of the stream from the farthest end point. Of the said starting source

Claims (9)

Disclaimers (all) that will not appear on the advertisement page: 1. The process for controlling the size and structure of carbon black aggregation Which consists of Passing a stream of hot combustion gas through a reactor Injecting the initial source into a stream of hot combustible gas at one or more points to cause a portion to flow out and initiate the fragmentation consisting of heat. The starting source in the section will flow out. The temperature reduction of the part to be discharged at point one within 0.002 s at the end of the current from the furthest end of the initial injection without causing the interruption of the separation. Containing the heat of the starting source In part to flow out 2. The process according to claim 1, where the temperature level of the Was reduced to approximately 426.67 ° C (800 ° F). 3. The process according to claim 1, where the temperature level of the Is reduced to between approximately 10 and approximately 426.67 ° C (50 to 800 ° F). 4. Clause 1 to 3 Clause 3 Clause 3 Temperature level of The discharge portion is reduced within a period of approximately 0.0 to approximately 0.0015 s from the furthest tip of the initial injection. 5. Movement according to any one of the claims 1 to 4 where the temperature The discharge part is reduced by injecting a suspension or cooling fluid. 6. The process for producing carbon black of a controlled size and aggregation structure consisting of Through a stream of hot combustion gas through the reactor The initial source is injected into the hot combustion gas stream at one or more points to form the outflow and initiate the heat-conduction of the The starting source is in the section that will flow out there. Lowering the temperature of the effluent at point one. Within a period of 0.002 s at the end of the stream from the far end of the injection, the starting source without interruption of the fragmentation consists of the heat of the starting source in the part to flow out, the reduction. The temperature of the part to be ejected a further lower at the point at the end of the stream of one point to stop the fragmentation, consisting of the heating of the starting source in the inlet and separation and collection of carbon products. Black 7. The process according to claim 6, where the temperature level of the Was reduced to approximately 426.67 ° C (800 ° F). 8. The process according to claim 7, where the temperature level of the part to flow out is Was lowered to a range of about 10 and about 426.67 degrees Celsius (50 and about 800 degrees F). 9. The process of claim 7 or 8 where the temperature level of the part to flow The output is reduced within an interval of approximately 0.0 and approximately 0.0015 s from the farthest end of the initial injection source 1. 0. Any of the claim procedures of Articles 7, 8, 9 or 10 where the temperature of the effluent is lowered by injecting a suspension fluid or reducing the heat level.
