Abstract
Catalysts and processes designed to convert DME and/or methanol and hydrogen (H2) to desirable liquid fuels are described. These catalysts produce the fuels efficiently and with a high selectivity and yield, and reduce the formation of aromatic hydrocarbons by incorporating H2 into the products. Also described are process methods to further upgrade these fuels to higher molecular weight liquid fuel mixtures, which have physical properties comparable with current commercially used liquid fuels.
Claims11
A method comprising:
- contacting at least one of dimethyl ether (DME) or methanol with hydrogen (H2) and a solid catalyst to produce a mixture comprising at least one of 2,2,3-trimethylbutane or 2,3,3-trimethyl-1-butene, wherein the solid catalyst comprises:
- a beta zeolite;
- metallic copper deposited on a surface of the beta zeolite;
- a total acid content between about 1900 μmol/g and about 2100 μmol/g;
- and
- a ratio of Brønsted acid sites to Lewis acid sites between about 0.5 and about 2.5.
