Preparation, characterization, and catalytic properties of SO42-/SnO2-Hangjin2#Clay solid superacid catalyst

Preparation of Solid Superacid SO42-/ZnO-TiO2 and Its Action on Synthesis of Dimethyl Carbonate from Urea and Methanol

SO42-/ZnO-TiO2 catalyst was prepared by sulfating ZnO-TiO2 powders with H2SO4 solution. The catalyst was characterized by XRD, IR and Hammett indicator. The catalyst showed strong acidity(H0 ≦-16.0). The optimum conditions are found that the calcination temperature is 823K and the so...

preparation of solid superacid so42-/zno-tio2 and its action on synthesis of dimethyl carbonate from urea and methanol

so42-/zno-tio2 catalyst was prepared by sulfating zno-tio2 powders with h2so4 solution. the catalyst was characterized by xrd, ir and hammett indicator. the catalyst showed strong acidity(h0 ≦-16.0). the optimum conditions are found that the calcination temperature is 823k and the soaked consistency of h2so4 is 1 mol/dm3. then so42-/zno-tio2 was applied as the catalyst in the catalytic synthesi...

Synthesis of Nanostructured MnNiAPSO-34 Catalyst: Catalytic Properties and Performance

Silicoaluminophosphate (SAPO-34) molecular sieve doped with transition metals, Mn and Ni, with different molar ratios (Mn/Ni=0.33, 3) were investigated for their activity, selectivity and lifetime in biomethanol to olefins reaction. MnNiAPSO-34 nanostructured catalyst was synthesized by hydrothermal method and addition of metals was carried out by isomorphous substitution into the crystalline f...
