Abstract:The steam reforming of dimethyl ether (SRD) has been proved to be one of the most promising routes for on-site H2 production. However, the two-step consecutive nature of the SRD reaction makes the design of an efficient bifunctional catalyst a challenge. Herein, a series of Cu incorporated into amorphous silica–alumina (Cu–ASA) as integrated bifunctional catalysts for SRD were synthesized by the single-step complex decomposition method, and ammonium carbonate was confirmed to be an effective complex agent for … Show more
“…This difference leads to the fact that typical MSR catalyst materials suffer from deactivation under these harsher SRD conditions. Most prominent among the catalysts tested for step (2) in the SRD sequence are Cu/ZnO/Al 2 O 3 (CZA), [21][22][23] Cu spinels [24][25][26][27] or metal oxide supported PGM group metals. [28][29][30] High DME conversions and hydrogen yields of above 90% have been achieved 25,31,32 with common side reactions being methanol decomposition (6), reverse water-gas-shi reaction (7) and methanation (8).…”
