  • Patent number: 12655361
    Abstract: A method for making C5-C8 alcohols includes converting a mixture of ethanol and water under suitable conditions into a reaction product mixture comprising a liquid phase and a gas phase, wherein the liquid phase comprises water, acetone, acetaldehyde, and diethylketone, and wherein the gas phase comprises carbon dioxide, hydrogen, C2-C4 olefins, and C1-C4 paraffins; hydrogenating the acetone and the diethylketone to yield isopropanol and 3 pentanol alcohol; and reacting ethanol, the isopropanol, and ethylene in the presence of peroxides of tertiary alcohols to form sec-butanol and tertiary C5-C8 alcohols.

  • Patent number: 12559691
    Abstract: A method for making a motor fuel includes converting a mixture comprising one or more C2-C4 alkenes, synthesis gas, and acetaldehyde to a mixture comprising C3-C4 aldehydes and C5-C8 aldols; hydrogenating the mixture comprising C3-C4 aldehydes and C5-C8 aldols to obtain a mixture comprising C3-C8 alcohols; converting the C3-C8 alcohols into C6-C24 paraffins; and isolating a fraction of the C6-C24 paraffins. The isolated fraction may be used to formulate a motor fuel.

  • Patent number: 12338403
    Abstract: A method for producing a motor fuel includes telomerizing ethylene and an alcohol mixture comprising ethanol under suitable conditions to form a mixture comprising C5-C8 alcohols; dehydrating the mixture comprising the C5-C8 alcohols to form a mixture comprising C5-C8 olefins; oligomerizing the C5-C8 olefins to form C10-C24 olefins; hydrogenating the C10-C24 olefins to form C10-C24 paraffins; and isolating a fraction of the C10-C24 paraffins. The isolated fraction may be used to form a motor fuel selected from gasoline, kerosene, diesel, and mixtures thereof.
