Sorption-enhanced ethanol steam reforming process in a fixed-bed reactor

Mostrar todas las versiones(2)

Sorption-enhanced ethanol steam reforming is an alternative to nonrenewable sources to produce high purity hydrogen by simplifying the purification train required to obtain cell grade hydrogen. In this work, NiMgAl hydrotalcite was used as a catalyst precursor and CaO as a sorbent. The catalyst-sorb...
