Abstract
A method and apparatus are provided for reforming impure methanol wherein residual gas produced during the reforming reaction is combusted simultaneously with residual gas coming from the purification of the hydrogen produced. The apparatus includes a tubular reactor in which the steam reforming is performed, a vaporizer for the reaction mixture, a heat exchanger to exchange heat between the outgoing gases and the feed liquid, a separator, a purification unit, and a combustion furnace for the residual purification gas. The apparatus further comprises a pipe for bringing in the condensed water-alcohol mixture to the combustion furnace, this pipe being equipped with two heat exchangers.
