Abstract Ni60Co40 nanoparticles supported on ?-Al2O3 capable of simultaneously catalysing the steam reforming reaction methane and supplying in-situ heat necessary to activate by induction heating, have been synthesized characterized. Energy is remotely promptly supplied an alternating radiofrequency magnetic field (induction heating system) that act as dissipating agents virtue their ferromagn...

A supported Pd-Au (Au 7wt%) membrane was produced by electroless plating deposition. Permeation tests were performed with pure gas (H₂, H₂, N₂, CO₂, CH₄) for long time operation. After around 400 h under testing, the composite Pd-Au membrane achieved steady state condition, with an H₂/N₂ ideal selectivity of around 500 at 420 °C and 50 kPa as transmembrane pressure, remaining stable up to 1100 ...

In this work it is analyzed the performance of an iron waste material as oxygen carrier for a chemical-looping combustion (CLC) system. CLC is a novel combustion technology with the benefit of inherent CO2 separation that can be used as a source of energy for the methane steam reforming process (SR). The tail gas from the PSA unit is used as fuel in the CLC system. The oxygen carrier behaviour ...

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...

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...

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...

Glycerol represents an emerging renewable bio-derived feedstock, which could be used as a source for producing hydrogen through steam reforming reaction. In this review, the state-of-the-art about glycerol production processes is reviewed, with particular focus on glycerol reforming reactions and on the main catalysts under development. Furthermore, the use of membrane catalytic reactors instea...

Methane reforming allows the production of synthesis gas (syngas) which is an important mixture feedstock for chemicals and energy carriers. Steam methane (SRM) partial oxidation (POM) have been deployed at large industrial scale, while dry (DRM) more recently tri-reforming (TRM) are intensively studied. TRM simultaneously combines SRM, POM DRM in a unique process overcoming several weaknesses ...
