Abstract: 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.

Abstract: A process for the production of hydrogen and/or carbon monoxide rich gases by steam reforming of a hydrocarbon feedstock, the process comprising the step of contacting the hydrocarbon feedstock and steam with a catalyst comprising nickel as a main catalytic component, a refractory carrier material for the nickel, and at least one catalytic element for the steam reforming of the hydrocarbon feedstock, the element being selected from the group consisting of germanium, tin, lead, arsenic, antimony and bismuth.
