The effect of SMSI (strong metal-support interaction) behavior on CO adsorption and hydrogenation on Pd catalysts: II. Kinetic behavior in the methanation reaction
TLDR
In this paper, a reaction model for Pd is proposed which is consistent with this behavior, with ir spectra of CO adsorbed on these Pd surfaces, and with recent results in the literature on CO hydrogenation.About:

Recent advances in methanation catalysts for the production of synthetic natural gas
TL;DR: In this paper, a comprehensive review of methanation catalysts for coal-or biomass-derived carbon oxides for production of synthetic natural gas (SNG) is provided, covering reaction thermodynamics, mechanism and kinetics, the effects of catalyst active components, supports, promoters and preparation methods.

Ordered Mesoporous Pd/Silica-Carbon as a Highly Active Heterogeneous Catalyst for Coupling Reaction of Chlorobenzene in Aqueous Media
TL;DR: The results clearly indicate that the pore wall nature shows great influence on the dispersion of metallic Pd species and, in turn, the catalytic performance.

Metal-support effects on the intramolecular selectivity of crotonaldehyde hydrogenation over platinum
M. Albert Vannice,Bishwajit Sen +1 more
TL;DR: In this article, the vapor phase hydrogenation of crotonaldehyde (CROALD) was studied at low temperature and low conversions over Pt powder and Pt dispersed on SiO2, η)-Al2O3, and TiO2 after either a high or a low-temperature reduction, HTR and LTR, respectively.

Mechanistic Aspects of the Formation of Hydrocarbons and Alcohols from CO Hydrogenation
TL;DR: In this article, it is shown that the world reserves of coal and natural gas far exceed those of oil, and this fact alone implies that the conversion of coal to transportation fuels is almost certain to become more widespread within the next 20 years.

The catalytic synthesis of hydrocarbons from H2CO mixtures over the group VIII metals: I. The specific activities and product distributions of supported metals
TL;DR: In this paper, specific catalysts were determined in the synthesis of hydrocarbons from CO-H2 mixtures over all the Group VIII metals except Os, and the methanation reaction was fitted to a power rate law of the form r CH 4 = Ae −Em RT P H 2 X P CO Y over all groups VIII metals.

Catalytic synthesis of hydrocarbons from carbon monoxide and hydrogen
TL;DR: The Fischer-Tropsch synthesis reaction as mentioned in this paper is commonly referred to as the Fischer reaction and is used to produce a variety of organic products from coal, residua, oil shale, and tar sands.

Methanation of carbon monoxide on nickel and nickel-copper alloys
TL;DR: In this paper, two steps of the overall mechanism have been identified, namely, dissociation of CO and hydrogenation of deposited carbon by adsorbed hydrogen, and they have been studied on Ni and Ni-Cu alloy films at low pressures, at temperatures of 250-350 °C.

Hydrogenation of surface carbon on alumina-supported nickel
Jon G. McCarty,Henry Wise +1 more
TL;DR: In this article, four types of carbon were observed to form on an alumina-supported nickel methanation catalyst on exposure to carbon monoxide at 550 ± 50 K. In order of their reactivity toward hydrogen, the carbon species may be classified as: chemisorbed carbon atoms (α), bulk nickel carbide, amorphous carbon (β), and crystalline elemental carbon.
