Abstract
Oxidative dehydrogenation catalysts for converting lower paraffins to alkenes such as ethane to ethylene when prepared as an agglomeration, for example extruded with supports chosen from slurries of TiO2, ZrO2 Al2O3, AlO(OH) and mixtures thereof have a lower temperature at which 25% conversion is obtained.
Claims21
An agglomerated catalyst comprising:
- 10 wt. % to 95 wt. % of a catalyst of the formula:
- Mo1.0V0.12-0.49Te0.06-0.16Nb0.15-0.20Od
- wherein d is a number to satisfy the valence of the oxide;
- and
- 5 wt. % to 90 wt. % of a binder chosen from TiO2, ZrO2 Al2O3, AlO(OH), and mixtures thereof provided that ZrO2 is not used in combination with an aluminum containing binder,
- wherein the agglomerated catalyst has a cumulative surface area of less than 35 m2/g as measured by BET.
