Abstract
Wholly biobased MTBE and ETBE fuel additive materials are described, together with fuel compositions including such additives and processes for making the wholly biobased MTBE and ETBE using isobutene prepared from acetic acid in the presence of a ZnxZryOz mixed oxide catalyst.
Claims5
A process for making a gasoline fuel additive, comprising:
- converting acetic acid to isobutene in the presence of a catalyst;
- and
- reacting the isobutene with at least one of methanol and ethanol, wherein the catalyst for converting the acetic acid to isobutene is a ZnxZryOz mixed oxide catalyst, wherein the ratio of x:y is from 1:100 to 10:1 and z is a stoichiometric integer for the mixed oxide catalyst.
