Rane, K.S.; Verenkar, V.M.S.; Sawant, P.Y. (Bulletin of Materials Science. 24(3); 2001; 331-338.)

Iron oxyhydroxides and hydroxides were synthesized from chemically beneficiated high SiO2/Al2O3 low-grade iron ore (57(.)49 percent Fe2O3) rejects and heated to get iron oxides of 96-99(.)73 percent purity. The infrared ...
Ammonolysis of ethanol on pure and zinc oxide modified HZSM-5 zeolites

Naik, S.P.; Fernandes, J.B. (Applied Catalysis A-General. 205(1and2); 2001; 195-199.)

Reaction between ethanol and ammonia have been studied on various zinc oxide modified HZSM-5 (Si/Al=225) catalysts under various conditions of temperature, C/N ratio of the reactants and their WHSV. Two pure zinc oxides ...
