Prospects and Technical Challenges in Hydrogen Production through Dry Reforming of Methane

CO-Free Production of Hydrogen via StepwiseSteam Reforming of Methane

CO-free hydrogen is produced by the reversible cyclic stepwise steam reforming of methane for use in fuel cells and other processes that are sensitive to CO poisoning. The process consists of two steps involving the decomposition of methane in a first step followed by steam gasification of the surface carbon in a second step. The ease of carbon removal in step II is strongly dependent on temper...

Production of hydrogen by unmixed steam reforming of methane

Dry Reforming of Methane Using Cold Plasma; Kinetic Model Study

In this work, the dry reforming of methane was studied using a corona and gliding discharge plasma microreactors. A chemical kinetic model was developed to describe the experimental behavior observed. The kinetic model is proposed based on the assumption that the reactant molecules CH4 or CO2 are attacked by active species produced b...

Investigation of the catalytic performance and coke formation of nanocrystalline Ni/SrO-Al2O3 catalyst in dry reforming of methane

In this study, nickel catalysts supported on mesoporous nanocrystalline gamma alumina promoted by various strontium contents were prepared by the impregnation method and employed in dry reforming of methane (DRM). The prepared catalysts were characterized using N2 adsorption (BET), temperature-programmed reduction and oxidation (TPR,) and oxidation (TPDTPO), X-ray diffraction (XRD), and scannin...

Heat and Power Integration Opportunities in Methane Reforming based Hydrogen Production with PSA separation

Hydrogen is getting increasing attention by government and industry leaders, [1], as a very environmentally attractive and clean fuel because its oxidation leads only to water formation. There is abundance of hydrogen in nature, although it is only available for exploitation in a combined state, either in water, hydrocarbons, or coal [2]. Its recovery from these natural resources requires the a...
