Abstract
In one embodiment, the invention is to a process for producing a catalyst composition for converting ethanol to higher alcohols, such as butanol. The process comprises contacting magnesium carbonate with one or more metal precursors to form a catalyst intermediate and calcining the catalyst intermediate to form the catalyst composition that comprises the one or more metals and magnesium oxide. The one or more metal precursors comprises one or more metal selected from the group consists of nickel, palladium, platinum, germanium, copper, ruthenium, gallium, tin, iridium, and mixtures thereof.
Claims25
A process for producing a catalyst composition for converting ethanol to butanol, the process comprising:
- contacting magnesium carbonate with one or more metal precursors, wherein the one or more metal precursors comprise one or more metals selected from the group consisting of nickel, palladium, platinum, germanium, copper, ruthenium, gallium, tin, iridium and mixtures thereof to form a catalyst intermediate;
- and
- calcining the catalyst intermediate to faun the catalyst composition comprises the one or more metals and magnesium oxide.
A process for producing higher alcohols, the process comprising the steps of:
- feeding a gaseous stream comprising ethanol over a catalyst composition in a reactor to form butanol, wherein the catalyst composition comprises a magnesium oxide with one or more metals, wherein the one or more metals are selected from the group consisting of nickel, palladium, platinum, gelinanium, copper, and ruthenium, wherein the catalyst is formed during calcination of a metal coated magnesium carbonate and having a high surface area and mesoporosity.
A catalyst composition for converting alcohols to higher alcohols, the catalyst is of the formula:
- Ma-M′b-M″c-MgO
- wherein M is palladium;
- M′ is germanium;
- M″ is nickel, platinum, ruthenium, or copper;
- and
- a is 0.001 to 0.1,
- b is 0 to 0.5, and
- c is 0 to 0.5.
