The dry reforming of methane is a process that produces syngas (a mixture of CO and H2) through the high-temperature reaction of methane with CO2 in the presence of catalysts via the reaction
CH4 + CO2 →2CO + 2H2.
This process has not yet reached commercialization due to catalyst damage from carbon formation.
Our research, in collaboration with the Bernal Institute at the University of Limerick, aims at understanding how carbon forms on the catalyst and how to avoid it while maintaining good performance, and developing stable and cheap catalysts for this process.
We are currently investigating three kinds of catalysts:
Systematically optimized conventional catalysts
Supported interstitial alloy catalysts
Liquid phase sulfur passivated catalysts
In addition, we model the reactive system to predict optimal, time-dependent operating conditions.
