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...

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...

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...

A small-size gasification unit is improved through process optimization to simulate industrial United Gas Improvement Company gasification. It finds that the reaction temperature has important impacts on semicoke catalyzed methane gas mixture. The addition of water vapor can enhance the catalytic activity of reforming, which is due to the fact that addition of water vapor not only removes carbo...

The use of a plasma reformer for the generation of hydrogen rich gas from diesel fuel has been investigated. A system that is normally used for investigating natural gas reforming has been modified in order to investigate the reforming of heavy liquid fuels. The composition of the reformate has been investigated as a function of the composition of the reagents. The use of a one-step reformer/wa...

This paper focuses on the comparison of different glycerol reforming technologies aimed to hydrogen and syngas production. The reactions of steam reforming, partial oxidation, autothermal reforming, dry reforming and supercritical water gasification were analyzed. For this, the Gibbs energy minimization approach was used in combination with the virial Equation of state. The validation of the mo...

This work initially focuses on developing a computational fluid dynamics (CFD) model of an industrialscale steam methane reforming reactor (reforming tube) used to produce hydrogen. Subsequently, we design and evaluate three different feedback control schemes to drive the area-weighted average hydrogen mole fraction measured at the reforming tube outlet ( x̄H outlet 2 ) to a desired set-point va...

Due to the feasibility of ethanol production in the United States, ethanol has become more attractive as a fuel source and a possible energy carrier within the hydrogen economy. Ethanol can be stored easily in liquid form, and can be internally pre-formed prior to usage in low temperature (200 o C – 400 o C) solid acid and polymer electrolyte membrane fuel cells. However, complete electrochemic...

The thermal valorization of glycerol to produce synthesis gas has been investigated under conventional and microwave heating systems. Different processes (pyrolysis, steam reforming and dry reforming) are compared, using a commercial activated carbon as catalyst. The reforming processes that employ oxidizing agents (CO2 or H2O) were found to promote higher glycerol conversions than mere termal ...
