摘要：

Vaporization of water leads to low levels of CO: Now, it is possible to produce low-CO-containing, H2-rich streams by simple, aqueous-phase reforming of oxygenates. The schematic of ethylene glycol reforming on a Pt catalyst shows the composition of a gas bubble in the aqueous-phase reactor. Lowering the H2 and CO2 pressures, by increasing the water pressure, lowers the CO concentration in the product. WGS = water-gas shift.
