Steam reforming of the crude glycerol by-product of a biodiesel production plant has been evaluated experimentally at atmospheric pressure, with and without in situ CO(2) sorption, in a continuous flow fixed-bed reactor between 400 degrees C and 700 degrees C. The process outputs were compared to those using pure glycerol. Thermodynamic equilibrium calculations were used to assess the effect on...

in this study, the modeling of hydrogen production process in microreactors by methanol-steam reforming reaction is investigated. the catalytic reaction of methanol-steam reforming producing hydrogen is simulated considering a 3d geometry for the microreactor. to calculate diffusion among species, mixture average correlations are compared to stephan-maxwell equations. the reactions occurring in...

Direct Reduction processes use gases (CO and H2) for iron reduction production of sponge or direct reduced (DRI). The generation this gas occurs through methane reforming, which can be done in a reformer inside the shaft with as catalyst. latter auto-reforming processes. kinetics steam reforming catalyzed by was studied at temperatures between 875°C 1050°C. Results showed that acts catalyst con...

Utilization of methane to produce chemicals has become attractive due to significantly reduced prices for methane gained from recent development in natural gas recovery. However, the lack of suitable catalysts for methane conversion (other than steam reforming) hinders its advances. While intensive research has been conducted on oxidative methane upgrading over decades, the carbon selectivity a...
