Claim Text:
1. A method for forming carbon allotropes, comprising: treating a carbonaceous compound to form a feedstock comprising at least about 10 mol % oxygen, at least about 10 mol % carbon, and at least about 20 mol % hydrogen; heating, via a heat exchanger, the feedstock with waste heat from a waste gas stream; forming carbon allotropes from the feedstock in a reactor in a Bosch reaction at a temperature of at least about 500° C.; separating, via a separator vessel disposed downstream of the reactor, the carbon allotropes from a reactor effluent stream, forming the waste gas stream having waste heat from the reactor; passing the waste gas stream through the heat exchanger to an ambient-temperature heat exchanger to condense water in the waste gas stream to give a dry waste gas stream; and passing the dry waste gas stream to a fractionation system comprising a separation column.
