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...

Two power plant schemes that reduce CO2 emission and employ natural gas reforming were analyzed and discussed. The first one integrates natural gas reforming technology for efficiency improvement with an oxy-fuel combined power system (OXYF-REF), with water as the main work fluid. The reforming heat is obtained from the available turbine exhaust heat, and the produced syngas is used as fuel wit...

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 ...

Blue hydrogen production by steam methane reforming (SMR) with carbon capture is far the most commercialised method, and addition of a simultaneous in-situ CO2 adsorption process, sorption-enhanced (SESMR) can further decrease cost H2 production. Ni-based catalysts have been extensively used for SMR because their excellent activity relatively low price, but deposition, sulphation, sintering lea...

We are interested in catalysts consisting either of substitutionally doped oxides (e.g. RuxCe1-xO2) or of submonolayers of an oxide supported on another oxide (e.g. VOx supported on ceria). Calculations and experiments show that in most cases these systems are more active catalysts than the original oxide (i.e. ceria). We use theory to try to find general patterns governing the activation by do...
