  • Feedstocks for forming carbon allotropes
    Patent number: 10351974
    Abstract: Methods and systems are provided for forming carbon allotropes. An exemplary method includes forming a feedstock that includes at least about 10 mol % oxygen, at least about 10 mol % carbon, and at least about 20 mol % hydrogen. Carbon allotropes are formed from the feedstock in a reactor in a Bosch reaction at a temperature of at least about 500° C., and the carbon allotropes are separated from a reactor effluent stream.
