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.
Claims16
A process for making carbon black particles, comprising:
- generating a plasma arc in 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, wherein the at least one hydrocarbon injector is cooled using a cooling liquid in thermal contact with the plasma arc, and wherein heat transferred to the cooling liquid from the plasma arc is less than about 20% of total energy input into the process.
