Abstract
An apparatus for producing solid carbon and water by reducing carbon oxides with a reducing agent in the presence of a catalyst includes a reactor configured to receive reaction gas comprising at least one carbon oxide, at least one reducing agent, and water. The apparatus includes at least one mixing means configured to mix the reagents to form a combined feed, a first heat exchanger configured to heat the combined feed, at least one heater configured to further heat the combined feed, and a reaction vessel configured to receive the combined feed. The reaction vessel is configured to contain a catalyst, to maintain predetermined reaction conditions of temperature and pressure, and has an output configured to deliver a tail gas to the first heat exchanger. The system also includes a product separator, a water separation unit, and a product packaging unit.
