A process for producing methanol is described in which a hydrocarbon is
steam reformed in a reforming zone, and during the reforming stage, of a
cyclic steam reformer having a reforming stage and a regeneration stage,
the steam reforming being conducted under conditions effective to produce
a first effluent stream containing synthesis gas. Fuel and an
oxygen-containing gas are combusted in the regeneration stage of the
reformer so as to reheat the reforming zone to a temperature sufficient
for the reforming stage and generate a flue gas. At least part of the
first effluent stream is contacted with a methanol synthesis catalyst
under conditions effective to convert synthesis gas to methanol and form
a methanol-containing stream and a tail gas stream comprising unreacted
carbon monoxide and hydrogen. At least part of the tail gas stream is
recycled as fuel for the regeneration stage of the cyclic steam reformer.
