A steam methane reformer (SMR) system includes an outer tube, wherein a first end of the outer tube is closed; an inner tube disposed in the outer tube, wherein a first end of the inner tube is open. A flow channel is defined within the inner tube and an annular space is defined between the outer tube and the inner tube, the flow channel being in fluid communication with the annular space. The SMR system includes a catalytic foam disposed in the annular space between the outer tube and the inner tube, the catalytic foam comprising a catalyst.

A method of forming a hydrocarbon product, the method comprising a first step of enriching a carrier liquid with carbon monoxide and hydrogen and a subsequent step of bringing the enriched carrier liquid into contact with a catalyst in a first reaction zone of a reactor, wherein the catalyst catalyzes reaction of the carbon monoxide and hydrogen to form the hydrocarbon product.

Methods, reactor tubes, reactors, and systems for catalysis are disclosed. A reactor tube includes an outer shell defining a catalyst bed, a catalyst within the catalyst bed, and an inner tube extending through the catalyst bed. An interior of the inner tube is isolated from the catalyst within the catalyst bed. Methods of activating a catalyst are also disclosed herein.

A method for producing hydrogen includes flowing a first gas along a bayonet flow path of a steam methane reformer (SMR) to produce a first product, including flowing the first gas through a foam disposed along the bayonet flow path; providing the first product produced in the SMR to an input of a water gas shift (WGS) reaction channel defined within a reaction tube of a WGS reactor; and flowing a second gas including the first product through the WGS reaction channel to produce a second product. Flowing the second gas includes flowing the second gas across a heat transfer material disposed in the WGS reaction channel to reduce the temperature of the flowing second gas; and flowing the second gas across a WGS catalyst disposed in the reaction channel.
