Calcium–nickel–lithium oxide: a high selectivity catalyst for the oxidative dehydrogenation of ethane to ethylene

Abstract

Novel calcium-nickel oxides promoted by alkali metal are shown to be highly selective for the oxidative dehydrogenation of ethane to ethylene; 93.6% selectivity for ethylene with 25% ethane conversion over Ca, Ni0.4Li0.35 oxide catalyst is attained at 600 "C.

Recent Advances in Polyoxometalate-Catalyzed Reactions

“…It has been reported that NiO serves dehydrogenation reactions. − However, single NiO is hard to employ as a stable catalyst with high catalytic performance because it is easily reduced to Ni 0 . The nanocomposites of NiO and Cs 2.5 H 0.5 PMo 12 with particle size in the range of 5–10 nm exhibit excellent catalytic performance in the oxidative dehydrogenation of propane and isobutane .…”

Coupling of thermal cracking with noncatalytic oxidative conversion of Ethane to Ethylene

“…The reactor must therefore be shut down so the coke can be removed. In order to overcome these problems, studies have recently been made throughout the world by many workers in the area of heterogeneous catalytic oxidative dehydrogenation of ethane to ethylene (Argent and Harris, 1986;Morales and Lunsford, 1989;Erdohelyi and Solymosi, 1990;Conway and Lunsford, 1991;Kennedy and Cant, 1991;Swaan et al, 1992;Desponds et al, 1993;Huff and Schmidt, 1993;Zhang et al, 1993;Burch and Crabb, 1993). We have also very recently studied the coupling of the therCorrespondence ccmceming this article should be addressed to V. R.

In vitro and in silico antioxydant activity, toxicity prediction, and molecular docking study of 3- and 3,3'-nitrophenylferrocene and their reduced amines

“…All these methods are based on measure thing the radicals scavenging activity of the studied antioxidant compounds against the appropriate free radicals like the superoxide anion radical ( 2O − . ) [10][11][12][13], the hydroxyl radical (OH • ) [14][15], the 1,1-diphenyl-2-picrylhydrazyl (DPPH • ) radical [16][17][18][19][20], or the peroxyl radical (ROO • ) [21][22][23][24]. Most work in the field of antioxidant activity is limited to the comparison of the antioxidant activity which are in most cases are not equal due to different applied technics.…”
