Popis: | It has been proved that a novel class of catalysts containing only titanium and zinc oxides with different Zn/Ti molar ratio is able to produce hydrogen by methanol reforming. Catalysts were characterised by X-ray diffraction. The influence of the reaction temperature, fed composition and catalyst composition were investigated. The best catalyst performances were obtained when χ Zn = 0.05. A comparative study on the steam reforming of methanol and combined reforming of methanol reactions was performed at the same conditions. The main by-products were CO, (CH 3 ) 2 O and CH 4 . Coke was formed when χ Zn ⩽ 0.02. In particular it was verified that a proper amount of zinc in the catalyst prevented coke and reduced by-products formation, however if χ Zn ⩾ 0.10 it limited the catalyst performances reducing surface area and forming zincite. |
