More Information
Summary:Systems and methods for producing syngas are provided. In at least one specific embodiment, a hydrocarbon can be reformed in the presence of steam and one or more first catalysts in a first reaction zone to provide an effluent containing a portion of the hydrocarbon, carbon monoxide, carbon dioxide, and hydrogen at a first temperature. The first reaction zone can include one or more catalyst-containing tubes. The effluent can be indirectly heated from the first temperature to a second temperature. The effluent at the second temperature can be reformed in the presence of one or more oxidants and one or more second catalysts at conditions sufficient to provide a syngas comprising hydrogen, carbon monoxide, carbon dioxide, and less than about 5% mol, dry basis, methane. The syngas can be used to indirectly heat the effluent from the first temperature to the second temperature.
