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...

Pd supported on ZnO has recently raised great interest as a catalyst for methanol steam reforming. Different from unsupported Pd, Pd-ZnO shows high selectivity and good conversion towards CO2 and hydrogen [1]. The difference is attributed to the formation of a PdZn alloy under reaction conditions, but there is still limited knowledge on the exact surface structure/composition and reaction mecha...

This work focuses on the support effect of performances Co based catalysts for acetic acid steam reforming. SBA-15, a well ordered hexagonal mesoporous silica structure, and CeO2 have been selected as supports, with impact chromium addition also being investigated. Better reforming recorded compared to SBA-15 supported and, in particular, 7Co/CeO2 catalyst showed highest values conversions enha...

There is a global push to develop a range of hydrogen technologies for timely adoption of the hydrogen economy. This is critical in view of the depleting oil reserves and looming transport fuel shortage, global warming, and increasing pollution. Molecular hydrogen (H2) can be generated by a number of renewable and fossil-fuel-based resources. However, given the high cost of H2 generation by ren...

The catalytic co-pyrolysis of a seaweed biomass, Laminaria japonica, and a typical polymer material, polypropylene, was studied for the first time. A mesoporous material Al-SBA-15 was used as a catalyst. Pyrolysis experiments were conducted using a fixed-bed reactor and pyrolysis gas chromatography/mass spectrometry (Py-GC/MS). BET surface area, N2 adsorption-desorption isotherms, and NH3 tempe...

Steam methane reforming is a major method of hydrogen production. However, this usually suffers from low energy efficiency and high carbon-emission intensity. To solve issue, novel steam-methane-reforming process over Ni-based catalyst in pressurized dual fluidized bed reactor proposed work. A three-dimensional computational fluid dynamics (CFD) model for the complex physicochemical was built t...

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...
