A structurally organized mesoporous CuO/CeO2/Al2O3 catalyst (8.3 % CuO, 17.0 % CeO2) was prepared by a new single-step template sol-gel synthesis, characterized by TGA, XRD, N2 adsorption and TPR, and tested for oxidative steam reforming of methanol (OSRM) at T = 200–400°C, H2O/CH3OH/O2 molar ratios = 1.1/1/0.12, CH3OH concentration = 17.8%, GHSV = 60000 h−1 . The catalyst contained Cu2+ species strongly interacting with CeO2, besides a CuO phase highly dispersed in alumina. After reduction in H2 the catalyst, compared with more conventional CuO/CeO2 systems, showed good activity and H2 yield in the OSRM process

Abstract
A structurally organized mesoporous CuO/CeO2/Al2O3 catalyst (8.3 % CuO, 17.0 % CeO2) was prepared by a new single-step template sol-gel synthesis, characterized by TGA, XRD, N2 adsorption and TPR, and tested for oxidative steam reforming of methanol (OSRM) at T = 200–400°C, H2O/CH3OH/O2 molar ratios = 1.1/1/0.12, CH3OH concentration = 17.8%, GHSV = 60000 h−1 . The catalyst contained Cu2+ species strongly interacting with CeO2, besides a CuO phase highly dispersed in alumina. After reduction in H2 the catalyst, compared with more conventional CuO/CeO2 systems, showed good activity and H2 yield in the OSRM processI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
