Effect of SO42− on catalytic activity of Fe2O3 for hydrocracking of coal

Metal atom based growth kinetics of low nuclearity metal clusters in liquid poly(dimethyl-co-methylphenylsiloxane). Part 2

“…In writing eq [5][6][7][8][9] we make two additional assumptions. In the first place it is assumed that colloid formation can be neglected.…”

Characterization of NiSO4Supported on Fe2O3and Catalytic Properties for Ethylene Dimerization

“…This catalyst also showed high catalytic activities for the polymerization of alkyl vinyl ether, 22 the double bond isomerization isomerization of 1-butene, 23 the ring-opening isomerization of cyclopropane, 23,24 the dehydration of 2-butanol, 23,24 and the liquefaction of coal. 25 Sulfated zirconia incorporating Fe and Mn has been shown to be highly active for butane isomerization, catalyzing the reaction even at room temperature. 26,27 Coelho et al have discovered that the addition of Ni to sulfated zirconia causes an activity enhancement comparable to that caused the addition of Fe and Mn.…”

Effect of Catalysts on the Pyrolysis of Turkish Zonguldak Bituminous Coal

“…Iron, copper, nickel, and zinc chlorides are mainly used as catalysts for liquefaction, gasification, and pyrolysis of coals. , The catalytic activity of Fe 2 O 3 for the hydrocracking of a bituminous coal increases when a small amount of SO 4 2- is included in the catalyst . The effect of nitrates of Cr(III), Mn(II), Fe(III), Co(II), Ni(II), Cu(II), and Zn(II) on the gasification rate and the composition of the evolved gases during steam gasification of Spanish lignite coke have been studied .…”
