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...
متن کاملHigh Coke-Resistance Pt/Mg1-xNixO Catalyst for Dry Reforming of Methane
A highly active and stable nano structured Pt/Mg1-xNixO catalysts was developed by a simple co-precipitation method. The obtained Pt/Mg1-xNixO catalyst exhibited cubic structure nanocatalyst with a size of 50-80 nm and realized CH4 and CO2 conversions as high as 98% at 900°C with excellent stability in the dry reforming of methane. The characterization of catalyst was performed using various ki...
متن کاملElectrodeposited Re-promoted Ni foams as a catalyst for the dry reforming of methane
Article history: Received 11 October 2015 Received in revised form 2 December 2015 Accepted 15 December 2015 Available online 17 December 2015 The dry reforming of methane (DRM) utilizes carbon dioxide (CO2) as the oxidizing agent in order to produce synthesis gas. Catalyst deactivation via coking, oxidation, and sintering has stymied the industrialization of catalysts for the DRM. Here, we uti...
متن کاملIn-Situ TEM Study of a Nanoporous Ni–Co Catalyst Used for the Dry Reforming of Methane
We performed in-situ transmission electron microscopy (TEM) on a dealloyed nanoporous NiCo catalyst used for the dry reforming of methane (DRM) to investigate the origin of the catalytic activity and structural durability. The in-situ observations and local chemical analysis indicated that the DRM induced chemical demixing of Ni and Co accompanied by grain refinement, implying possible “synergi...
متن کاملSyngas from CO2 Reforming of Coke Oven Gas: synergetic effect of activated carbon / Ni-γAl2O3 Catalyst
The CO2 reforming of coke oven gas for the production of synthesis gas has been studied over an activated carbon, an in-lab prepared Ni/Al2O3 catalyst and physical mixtures of both materials in different proportions (AC+Ni) at 800 oC. It was found that there are two possible coexisting reaction pathways: the direct dry reforming of methane (decomposition of methane followed by gasification of t...
