Abstract

Removal of carbon monoxide from the H2-rich stream during fuel generation from hydrocarbons is a critical challenge, especially for proton exchange membrane fuel cell (PEMFC) applications. Herein, CO an initial concentration of 1.0 vol. % was successfully removed from a H2-rich stream to a residual level below 10 ppm, within the wide operating temperature range from 92 to 235 oC by utilizing a hybrid channel reactor comprising a micro-channel heat exchanger and mini-packed bed reactor. The mini-packed bed reactor contained two kinds of catalysts that promote preferential oxidation and methanation of CO in series. The hybrid micro- And mini- channel reactor (HMCR) offers not only ultimately safe operation but also easy scale-up and is adaptable to mass production of CO clean-up units.
