Novel catalytic reactor for oxidative reforming of methanol

Combined steam reforming of methanol over Cu–Mn spinel oxide catalysts

“…Assuming prevaporized reactants, Eq. (4) is thermally neutral ( H • = 0 kJmol −1 ) when the oxygen-to-methanol ratio is equal to 0.1 [5]. Experimental studies on the CSRM process are limited compared with those concerning SRM and focus mainly on copper-based catalysts supported on ZnO, ZnO/Al 2 O 3 , or CeO 2 and group 8-10 metal-based catalysts supported on ZnO or ZnO/CeO 2 [6,7].…”

Catalytic Steam Reforming Technology for the Production of Hydrogen and Syngas

“…By this procedure, it is possible to obtain intimately interacting Pd -Zn species that easily generates the 1:1 Pd/Zn alloy when reduced at 500 ° C. Chen et al 117 reported the use of a wall -coated, highly active PdZn/CuZnAl mixed catalyst for the OSRM in a microchannel reactor. High H 2 yields in the OSRM reaction was also observed in a microchannel reactor by Lyubovsky and Roychoudhury et al 208 Suwa et al 202 reported the performance of various supported Pd/ZnObased catalysts. Although much more stable than Cu -based catalysts, deactivation of PdZn catalysts was reported.…”

A reforming system for co-generation of hydrogen and mechanical work from methanol

“…Autothermal reforming of alcohols into hydrogen has been demonstrated by many researchers [4][5][6][7]. In our previous work, complete conversion of methanol in adiabatic ATR reactor was demonstrated with near equilibrium product composition and about 50% H 2 and less than 2% CO in the reformate stream [6].…”

“…Details of system integration and description of the assumptions used in modeling of individual components for the described system was provided in [9]. The difference between this and our previous work is based on the fact that methanol can be converted to CO and H 2 at much lower temperatures than methane, which allows combining reforming and water-gas-shift steps within a single reactor [6]. Reformate temperature for such an ATR reactor can be compatible with a Pd-based membrane, such that no stream conditioning between these process elements would be required.…”

“…Alcohols can be converted into hydrogen through steam reforming [1][2][3] or autothermal reforming [4][5][6][7] processes. Selection between these two approaches depends on the details of the reformer integration into the fuel processing system and an assessment of overall system efficiency, size and complexity.…”
