Environmental issues related to greenhouse gases (GHG) emissions have pushed the development of new technologies that will allow economic production low-carbon energy vectors, such as hydrogen (H2), methane (CH4) and liquid fuels. Dry reforming (DRM) has gained increased attention since it uses CH4 carbon dioxide (CO2), which are two main (GHG), feedstock for syngas, is a mixture H2 monoxide (C...

Abstract: Hydrogen production via Sorption-Enhanced Chemical-Looping reforming combines hydrocarbons reforming (in this case methane reforming), by chemical-looping auto-thermal reforming, with water-gas shift and carbonation reactions. Both H2 production rate and concentration depend on the chemical equilibrium that is established in the fuel reactor and that is influenced by several parameter...

Internal dry reforming of methane is envisaged as a possibility to reduce on capital and operation costs biogas fuelled solid oxide fuel cells (SOFCs) system by using the CO2 present in biogas. Due internal reforming, requirement for upgrading becomes obsolete, thereby simplifying complexity increasing its technology readiness level. However, impurities prevailing such H2S have been reported li...

The CO2 (dry) reforming of hydrocarbons offers an opportunity to convert greenhouse gases into synthesis gas, which can further transform various valued products. Here we explore the influence Rh particle size and support on propane methane. To that end, nanoparticles with controlled sizes varying from 1.6-8.0 nm were synthesized following a polyol reduction method then dispersed three differen...

This work investigated the steady state and dynamic simulation of a fixed bed industrial naphtha reforming reactors. The performance of the reactor was investigated using a heterogeneous model. For process simulation, the differential equations are solved using the 4th order Runge-Kutta method .The models were validated against measured process data of an existing naphtha reforming plant. The r...

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 ...

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...

Introduction Reforming (i.e., partial oxidation, steam reforming, or autothermal reforming (ATR)) of infrastructure fuels, such as natural gas, liquefied petroleum gas, gasoline, or diesel, is one approach being investigated for distributed H2 production for use with fuel cell systems being developed for automotive and stationary applications. One area of interest is reforming gasoline either o...

Technical Targets The goal of this project is to develop a cost effective and feedstock flexible technology for reforming of biomass feedstocks. The synergistic improvement in reforming catalysts and reaction engineering will help the reforming technology development that meets the following DOE 2010 targets for distributed production of hydrogen from bio-derived renewable liquids: • Cost: $3.6...
