Microfibrous entrapment of Ni/Al2O3 for dry reforming of methane: a demonstration on enhancement of carbon resistance and conversion

Abstract

Microfibrous entrapment technology in process intensification was demonstrated in the dry reforming of methane. The 8 μm-copper microfibrous entrapped Ni/Al₂O₃ (Cu-MFE-Ni/AlO) catalyst, with excellent permeability, provided great heat transfer enhancement, thereby leading to significant improvement of carbon resistance by a thermodynamic route along with visible conversion promotion. For instance, at a temperature of 1073 K, 4-fold reduction of average carbon deposition rate was achieved in the Cu-MFE-Ni/AlO composite bed compared to the packed bed of Ni/AlO.
