Electrified methane steam reforming on a washcoated SiSiC foam for low‐carbon hydrogen production

AIChE Journal, Volume 69, Issue 1, January 2023., 2023
Abstract In view of largely available renewable electricity as a green future resource, here we report the electrification of a Rh/Al2O3 washcoated SiSiC foam for methane steam reforming (MSR). We show that, thanks to the suitable bulk resistivity of the SiSiC foam, its direct Joule heating up to relevant temperatures is feasible; the interconnected ...
