CO2 Methanation of Biogas over Ni-Mg-Al: The Effects of Ni Content, Reduction Temperature, and Biogas Composition

THE INFLUENCE ON Ni-CONTENT ON THE Ms-TEMPERATURE OF Cu-Zn-Al-Ni ALLOYS

Reforming of Biogas over Co- and Cu-Promoted Ni/Al2O3-ZrO2 Nanocatalysts Synthesized via Sequential Impregnation Method

Utilization of active and stable catalyst could have enormous advantages in industrial application of biogas reforming. In order to achieve this goal, the effects of Cu and Co as promoters were investigated over physical-chemical properties of Ni/Al2O3-ZrO2 catalyst in reforming of biogas. The sequential impregnation was used for preparation of catalysts. The catalysts were characterized using ...

Kinetic studies of CO2 methanation over a Ni/γ-Al2O3 catalyst.

The production of methane by reacting CO2 with H2 (CO2 methanation) has the potential for producing synthetic natural gas, which could be exported using the existing infrastructure for the distribution of natural gas. The methanation of CO2 was investigated over a wide range of partial pressures of products and reactants using (i) a gradientless, spinning-basket reactor operated in batch mode a...

Creep of Ni-Al and Ni-Cr-Al Superalloy Foams

The steady-state creep rate of Ni-base metallic foams, with superalloy composition (in wt. pct) Ni7.8∼9.1Al (relative density, ρ = 2.5-2.6) and Ni-13.5∼16.6Cr-5.1∼8.9Al (ρ = 2.8∼3.0), was measured under a range of temperatures (680∼825°C) and applied stresses (0.1∼0.3 MPa), and compared with that of NiAl intermetallic foams (ρ = 5.3). The stress exponent and activation energy are within the exp...
