QUICK-START SYSTEM FOR PREPARING HYDROGEN VIA AQUEOUS METHANOL, AND HYDROGEN PREPARATION METHOD

摘要

Disclosed are a quick-start system for preparing hydrogen via aqueous methanol, and hydrogen preparation method. The system comprises a liquid storage container, a raw material feeding device, a quick-start device, hydrogen preparation equipment and a membrane separation device; the quick-start device comprises a first start device and a second start device; the first start device comprises a first heating mechanism and a first gasification pipeline, the first gasification pipeline winding around the first heating mechanism; one end of the first gasification pipeline is connected to the liquid storage container, and feeds methanol into the first gasification pipeline via the raw material feeding device, for the first heating mechanism to heat and gasify; the hydrogen preparation equipment comprises a reforming chamber; the second start device comprises a second gasification pipeline, the main body of the second gasification pipeline being disposed in the reforming chamber; and the methanol outputted by the first gasification pipeline and/or the second gasification pipeline heats the second gasification pipeline while heating the reforming chamber, thus gasifying the methanol in the second gasification pipeline. The present invention can be quickly started, while having less energy consumption and good practicability.
