Abstract
A method of producing a catalyst comprises forming a decomposed material comprising a decomposed hydrotalcite, a decomposed hydrocalumite, or a combination of both, combining the decomposed material with a mixture to form a catalyst mixture, and heating the catalyst mixture to convert the metal salt to a metal oxide. The mixture comprises a metal salt and a chelating agent, and the resulting metal oxide combined with the decomposed material forms the catalyst.
Claims20
A method for producing a higher alcohol comprising:
- contacting a reactant comprising ethanol with a catalyst at a reaction temperature and pressure sufficient to produce a reaction product, wherein the catalyst comprises a decomposed hydrotalcite, a decomposed hydrocalumite, or a combination of both mixed with one or more metal oxides, wherein the reaction product comprises a higher alcohol, unreacted ethanol, and an ester;
- separating the unreacted ethanol from the reaction product;
- separating substantially all of the ester from the unreacted ethanol to form an ethanol recycle stream;
- and
- recycling the ethanol recycle stream to contact the catalyst.

A method of producing a catalyst comprising:
- decomposing material to form a decomposed hydrotalcite, a decomposed hydrocalumite, or a combination of both;
- combining the decomposed material with a mixture to form a catalyst mixture, wherein the mixture comprises a metal salt;
- and
- heating the catalyst mixture to convert the metal salt to a metal oxide, wherein the resulting metal oxide combined with the decomposed material forms the catalyst, and wherein at least one of the decomposing or the heating comprises applying heat at a temperature between 600° C. and 750° C.
