Catalytic removal of nitrates from waters
(2010)The selective catalytic reduction of nitrates (NO3 -) in pure water towards N2 formation by the use of gaseous H2 and in the presence of O2 (air) at 1 atm total pressure and 25 °C has been investigated over Pd-Cu supported ...

Kinetics of methane oxidative coupling on zinc-doped titanium oxide
(1992)A kinetic study of methane conversion to C2-hydrocarbons was conducted by cofeeding methane and oxygen at 1 bar total pressure over a series of zinc-doped TiO2 catalysts. The zinc dopant concentration was varied between 1 ...

Selective catalytic reduction of NO by H2/C3H6 over Pt/Ce1-xZrxO2-Δ: The synergy effect studied by transient techniques
(2017)A series of Pt/CexZr1-xO2-δ(x = 0.4–0.6) solids were synthesized and evaluated for the SCR of NO under lean burn conditions (2.5 vol% O2) using C3H6and H2as reducing agents. SSITKA-Mass Spectrometry, SSITKA-DRIFTS and other ...

The selective oxidation of methane to C2-hydrocarbons over lithium-doped TiO2 catalysts
(1994)The oxidative coupling of methane (OCM) to C2-hydrocarbons was studied on a series of lithiumdoped titania catalysts by cofeeding methane (PCH4 = 0.5 bar) and oxygen (Po2 = 0.07-0.16 bar) at 1 bar total pressure in the ...
