The dry reforming of methane using CO2 (DRM) has been extensively investigated since the catalytic reaction converts primary greenhouse gases such as CH4 and CO2 to value-added syngas (H2 and CO). However, the significant hurdles to implement the DRM catalyst in the real process are (1) cheap and facile synthesis without complex catalytic formulation and preparation step, (2) superior thermal durability with zero nature of carbon deposition and (3) excellent conversion of CO2 and CH4 to stoichiometric 1:1 formation of CO and H2. Motivated by this, we have developed a promoter-free Ni-based catalyst in which confined Ni nanoparticles are embedded in amorphous silica networks. At this KIChE spring meeting, we will present the world’s best performance of DRM catalyst, exhibiting 500 hours of outstanding long-term stability and superior feed capacity (250 L/gcatal/h) without any clue of deactivation. |
