摘要

Severe conditions involved in hydrogen storage and transportation limit the practical applications of hydrogen denitration reaction. In this paper, we developed a new process that consists of methanol steam reforming inline hydrogen production coupled with denitration, which reduces the threshold use of hydrogen. The bifunctional CuZnOx-X-MnPdOz@Ni catalyst prepared in this paper could achieve inline hydrogen production through the CuOx center and reduce NOx by the MnPdOz center. The optimal CuZnOx-CeZrOy-MnPdOz@Ni candidate catalyst could maintain over 90% denitration efficiency under conditions: GHSV = 22 000 h(-1) + n(methanol) : n(water) = 1 : 1.3 + 800 ppm NO at 150 degrees C. We conducted various characterization methods to reveal the valence state distribution of the promising catalyst. The experimental results indicated that the inline hydrogen selective catalytic reduction of NO is a promising strategy for green, efficient, and sustainable NOx control technology.
