Abstract
A torch stinger apparatus may comprise one or more sets of plasma generating electrodes and at least one hydrocarbon injector contained within the electrodes. The electrodes may be concentric. The at least one hydrocarbon injector may be cooled. A method of making carbon particles using the apparatus is also described.
Claims38
A carbon black particle generating reactor, comprising:
- a plasma generating section containing one or more sets of concentric electrodes configured to generate a plasma;
- a reactor section connected to the plasma generating section;
- and
- an injector located within the concentric electrodes, wherein temperature centrally within the concentric electrodes is less than a temperature of the plasma generated by the concentric electrodes.

A process for making carbon black particles, comprising:
- generating a plasma arc in a high temperature zone of a reactor with concentric plasma generating electrodes;
- and
- injecting a hydrocarbon into the reactor to form the carbon black particles, wherein the hydrocarbon is injected into the reactor through at least one hydrocarbon injector located within the concentric plasma generating electrodes, and wherein heat loss during the process due to the at least one hydrocarbon injector is less than about 20% of total energy input into the process.
A method for making carbon black particles, comprising:
- flowing a thermal transfer gas between electrodes in a reactor;
- generating a plasma arc with the electrodes;
- and
- injecting a hydrocarbon into the reactor to form the carbon black particles, wherein the hydrocarbon is injected into the reactor through at least one hydrocarbon injector located within the electrodes, and wherein the carbon black particles have a transmittance of toluene extract greater than or equal to about 94%.
