Abstract:
1. A steam methane reformer, comprising: a tube and shell reactor having an outer shell and a reactor core inside the outer shell, wherein the outer shell and an exterior wall of the reactor core define a shell side annulus configured to heat the reactor core present on the tube side of the tube and shell reactor; a plurality of hot fluid inlets connected to the shell of the tube and shell reactor to permit fluid passage of a heating medium into the shell side annulus; no more than one hot air outlet connected to the shell of the tube and shell reactor to permit fluid passage of the heating medium out of the shell side annulus; wherein the reactor core comprises a feed inlet, a porous zone containing a solid catalyst and a product outlet, wherein a reaction takes place in the porous zone; wherein the product outlet is connected to the reactor core and is configured to pass products of the reaction out of the reactor core; wherein the plurality of hot fluid inlets are fixed at a spiraled rotational pattern along the shell side of the tube and shell reactor; wherein the hot air outlet is positioned away from the feed inlet and is adjacent to the product outlet; and wherein the hot air outlet lies parallel to the product outlet and is position along the axis of fluid flow.
