Acidic sites in beta zeolites in dependence of the preparation methods
Beta zeolites synthesized by different methods are compared in their structure peculiarities and acidic properties by nitrogen physisorption, IR-KBr, pyridine sorption-desorption and thermoprogrammed desorption of ammonia. ...
Fe containing ZSM-5 zeolite as catalyst for wet peroxide oxidation of orange II
(De Gruyter, 2011)
This study presents the catalytic performances of iron containing ZSM-5 zeolites, prepared by ion exchange or hydrothermal synthesis, in catalytic Fenton-like oxidation of Orange II in aqueous solution. The catalyst, ZSM-5 ...
Characterization and catalytic activity of CuFeZSM-5 catalysts for oxidative degradation of Rhodamine 6G in aqueous solutions
This study presents an evaluation of the catalytic performances of Fe and Cu containing ZSM-5 zeolites for oxidation of Rhodamine 6G. Fe and Cu were loaded by ion exchange or through hydrothermal synthesis. The catalytic ...
Isomerisation of α-pinene over Beta zeolites synthesised by different methods
Liquid-phase α-pinene isomerisation at l00°C in a batch reactor is studied over Beta zeolites synthesised by different methods. It is confirmed that α-pinene forms a carbenium ion in an acidic environment, which rearranges ...
Liquid phase transformation of α-pinene over Beta zeolites containing aluminium or boron, titanium and vanadium as lattice ions
Beta zeolites with different modules (SiO2/Al2 O3) and containing B, Ti or V in lattice positions were synthesised by different methods and tested as catalysts in liquid phase transformation of α-pinene at 100 °C in a batch ...
