  • Patent number: 10669221
    Abstract: A method of producing a catalyst can include heating a hydrotalcite above a decomposition temperature, forming a decomposed hydrotalcite in response to the heating, combining the decomposed hydrotalcite with a metal salt to form a catalyst mixture, and heating the catalyst mixture to convert the metal salt to a metal oxide. The resulting metal oxide combined with the decomposed hydrotalcite forms the catalyst.

  • Patent number: 10081588
    Abstract: A reactive distillation method comprises introducing a feed stream to a reactive distillation column, wherein the feed stream comprises ethanol, contacting the feed stream with one or more catalysts in the reactive distillation column during a distillation, and removing butyl acetate during the distillation from the reactive distillation column as a bottoms stream. The feed stream reacts in the presence of the one or more catalysts to produce a reaction product comprising ethyl acetate, butanol, and water, wherein the butanol and the ethyl acetate react to produce a reaction product comprising the butyl acetate.

  • Patent number: 9771308
    Abstract: Olefins and diolefins, such as 1,3-butiadiene, may be produced by a method utilizing a series of bromination and dehydrobromination reactions. Bromine may be reacted with n-butane to form dibromobutane. The dibromobutanes may be dehydrobrominating to form 1,3-butadiene. The method may include reacting butene with bromine to form bromobutenes, and dehydrobrominating the bromobutenes to form 1,3-butadiene. The method may include reacting butene with hydrogen bromide in the presence of oxygen to form bromobutenes, and dehydrobrominating the bromobutenes to form 1,3-butadiene. The method may include reacting butene with bromine to form dibromobutanes, and dehydrobrominating the dibromobutanes to form 1,3-butadiene.
