1. A method of making carbon black particles in an enclosed particle generating reactor, comprising:
generating a plasma comprising at least 60% by volume hydrogen with plasma generating electrodes in a reactor, wherein an interior dimension of the reactor is at least 10% smaller downstream of the plasma generating electrodes;
injecting, through injectors, hydrocarbon either at a point where the interior dimension is smallest or further downstream from the plasma generating electrodes to form carbon black particles comprising a first amount of a combustible gas, wherein a sum of diameters of the injectors is greater than 5% of a circumference of a cross-sectional plane of the reactor where the injectors are co-located; and
reducing the combustible gas present in the carbon black particles such that the carbon black particles comprise a second amount of the combustible gas after said reducing, wherein the second amount is less than 10% of the first amount.
