Abstract
This disclosure provides systems, methods, and apparatus related to catalysts. In one aspect, a catalyst is a ZnxMy/zeolite catalyst, with ½≤x/y≤4, and M being a metal from a group Cr, Mo, and W. Zn is an oxide, M is an oxide, and there are at least some ZnMOx oxides.
Claims22
A method comprising:
- mixing a Zn precursor, a metal precursor, and a zeolite to form a mixture;
- grinding the mixture;
- and
- after grinding the mixture, heat treating the mixture to form a Zn3M1/zeolite catalyst, wherein M is a metal selected from the group consisting of Cr, Mo, and W, and wherein Zn and M form at least some ZnMOx oxides.
