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 ZnZrOmixed oxide catalyst.

Process for making biobased fuel additives

Processes are described for making biobased isoprene, wherein a biobased isobutene prepared from acetic acid in the presence of a catalyst is combined with a formaldehyde source to form a reaction mixture, and the reaction mixture is reacted to yield biobased isoprene. In certain embodiments, methyl-tert-butyl ether prepared by reacting the same biobased isobutene with methanol serves as a formaldehyde source, being oxidatively cracked to produce formaldehyde as well as isobutene for being converted to the biobased isoprene.

Process for making biobased isoprene

Processes are described for making methacrylic acid via methacrolein from a biobased isobutene, wherein the biobased isobutene is prepared from ethanol or from acetic acid in the presence of a ZnZrOmixed oxide catalyst, the biobased isobutene is oxidized to methacrolein and the methacrolein is further oxidized to methacrylic acid.

Processes for making methacrylic acid

A process is disclosed for converting acetic acid to isobutene in the presence of a catalyst. In certain embodiments, a ZnZrOmixed oxide catalyst is used for carrying out a gas phase process for converting acetic acid to isobutene. In some embodiments, a ZnZrOmixed oxide catalyst made by an incipient wetness impregnation method is used and is indicated to be very stable for carrying out the conversion.

Process and catalyst for conversion of acetic acid to isobutene

A process is disclosed for converting acetic acid to propylene and isobutene as the principal hydrocarbon products made, in the presence of a catalyst and in the further presence of hydrogen. In certain embodiments, a ZnZrOmixed oxide catalyst is used for carrying out a gas phase process, and propylene is produced preferentially to isobutene by using at least a certain amount of hydrogen in the process. In some embodiments, a ZnZrOmixed oxide catalyst made by an incipient wetness impregnation method is used and is indicated to be very stable for carrying out the conversion.

Process and catalyst for conversion of acetic acid to isobutene and propylene

A process is described for making renewable para-xylene, comprising converting acetic acid to isobutene in the presence of a catalyst then converting the acetic acid-derived isobutene to a product composition including para-xylene. The catalyst can be a ZnZrOmixed oxide catalyst.

Renewable para-xylene from acetic acid

A process is described for making renewable isobutene and renewable isoprene, comprising converting a mixed acid feed including acetic acid and propionic acid to a product mixture including isobutene and at least one or both of 2-methyl-1-butene and 2-methyl-2-butene in the presence of a catalyst, separating isobutene from the product mixture and dehydrogenating either or both of the 2-methyl-1-butene and 2-methyl-2-butene in the remainder to provide isoprene.

Renewable isobutene and isoprene from a mixture of acetic acid and propionic acid

A process is described for making a product mixture including isobutene, propylene, 1-butene, 2-butene, 2-methyl-1-butene and 2-methyl-2-butene from a mixture of acetic acid and propionic and through reaction in the presence of a source of hydrogen and of a mixed oxide catalyst, for example, a ZnZrOmixed oxide catalyst. A variety of commercially valuable products may be made in turn from the various C, Cand Cconstituents of the product mixture.

Renewable olefins from a mixture of acetic acid and propionic acid

Processes are described for improved utilization of the byproduct acetic acid universally produced in various oxidative processes for making acrylic acid and methacrylic acid, wherein at least a portion of the byproduct acetic acid is converted to isobutene and optionally to one or more further value-added products which may be prepared from isobutene.
