Claim:
1. A system for the production of carbon nanotubes, comprising: a feed gas heater comprising a heat exchanger configured to heat a feed gas with waste heat from a waste gas stream; a reactor configured to receive the feed gas from the feed gas heater and to form carbon nanotubes from the feed gas on catalyst in a Bosch reaction, and to discharge a reactor effluent stream, wherein the reactor is a fluidized bed reactor; a separator configured to separate the carbon nanotubes from the reactor effluent stream, forming the waste gas stream; and a water removal system comprising an ambient temperature heat exchanger and a separation vessel, the water removal system configured to separate a bulk of water from the waste gas stream to form a dry waste gas stream.
