Methods of converting ethane to ethylene at relatively low temperatures are described. Ir02-based catalysts are used in the conversion. Methods of converting a base gas to a first gas by exposing the base gas to an IrO2-based catalyst and forming the first gas are described. The base gas ...

from the variety of metal oxides examined in this work. CeO2 nanocrys‐tals with rod and cube morphologies showed higher ethane conversions and ethylene selectivities than CeO2 nanoparticles. The modification of CeO2 by MnOx further enhanced the catalytic perfor‐mance. Ethane conversion of 94% ...

To achieve a low rate of production of precursors we use poorly soluble metal oxide precursors, i.e., MoO3, V2O5, TeO2 and Nb2O5. Their rate of dissolution was adjusted by addition of citric acid, monoethylene glycol and oxalic acid as complexing agents. The presence of these additives ...
The room-temperature CH activation of ethane by metal-free SO2.+ radical cations has been investigated under different pressure regimes by mass spectrometric techniques. The major reaction channel is the conversion of ethane to ethylene accompanied by the formation of H2SO2.+, the radical cation of...
The ethane conversion (XC2H6), the yield of ethylene (YC2H4) and selectivity to ethylene (SC2H4) were calculated as follows:(1)XC2H6%=100×(FC2H6)in-(FC2H6)out(FC2H6)in(2)SC2H4%=100×FC2H4(FCH4+FC2H4)(3)YC2H4%=100×FC2H4(FC2H6)inwhere Fi is the molar flow rate of each com...
we demonstrate a photochemical looping strategy for highly selective stoichiometric conversion of methane to ethane at ambient temperature over silver–heteropolyacid–titania nanocomposites. The process involves a stoichiometric reaction of methane with highly dispersed cationic silver under illumination, which ...
