The disclosure provides catalyst composition for converting propylene glycol and glycerol to acrolein comprising a catalyst having the formula:
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒM1M2 x M3 y O z
wherein M1 is a metal promoting dehydrogenation and C-O cleavage,
wherein M2 is a metal with acid sites promoting dehydration,
wherein M3 is an amphoteric catalyst support, with acid and base sites, promoting both dehydration and dehydrogenation in conjunction with M1,
wherein x is a molar ratio from about 0.25 to about 4,
wherein y is a molar ratio from about 0.25 to about 4,
wherein z is the total amount of oxygen bound to M1, M2, and M3, and corresponds to the sum of the oxidation states of M1, M2, and M3. The catalyst composition may be used in a method for converting propylene glycol into acrolein. Subsequently, the acrolein may be converted into acrylonitrile.
Also disclosed is a method for producing a first product comprising ethylene glycol, propylene glycol, and glycerol by converting C5 and/or C6 sugars. |
