A bubbling fluidized bed membrane reactor for steam reforming of higher hydrocarbons is modelled, using n ‐heptane as a model component to represent steam reforming of naphtha. The reformer is modelled as a bubbling fluidized bed reactor, consisting of two pseudo phases, a dense phase and a bubble phase, both in plug flow. In situ H 2 permselective membranes remove H 2 continuously as a pure product, greatly enhancing the H 2 yield per mole of heptane fed. A fluidized bed membrane reformer for higher hydrocarbons could give a very compact reactor system combining all the units from the pre‐reformer to the hydrogen purification system in a traditional steam reforming plant into a single unit.
