ABSTRACT:
A graded temperature methanol reactor includes an inclined container containing a liquid heat transfer medium, such as water, having a varying temperature along the container. Conduits, extending through the container and in contact with heat transfer medium, conduct a feed gas having hydrogen and carbon monoxide and permit heat transfer between the feed gas and the heat transfer medium. A copper catalyst is disposed within each conduit to cause the hydrogen and carbon monoxide to react to form methanol, which condenses as the temperature decreases along the container from the upper end to the lower end. Preferably, the conduits are configured as a rotor and can be rotated relative to the container. By using this methanol reactor, methanol can be produced from a feed gas having hydrogen and carbon monoxide in a 2:1 molecular ratio, regardless of the source of this feed gas. For example, this feed gas can be produced by a biomass gasification and reforming process, and the methanol reactor can be interrelated with the gasification process.
