摘要： Methods for utilizing carbon dioxide to produce multi-carbon products are disclosed. The systems and methods of the present disclosure involve: reducing CO2 to produce a first product mixture comprising an alcohol product mixture comprising one or more alcohols and a paraffin product mixture comprising one or more paraffins; dehydrating the alcohol product mixture to form an olefin product mixture comprising one or more olefins; oligomerizing the olefin product mixture to form a higher olefin product mixture comprising unsaturated paraffins and optionally aromatics; and reducing the higher olefin product mixture to form a higher hydrocarbon product mixture comprising unsaturated paraffins and optionally aromatics. Catalyst materials and reaction conditions for individual steps are disclosed to optimize yield for ethanol or jet fuel range hydrocarbons.

摘要： Methods for producing alcohols by deriving carbon dioxide from air or another dilute source, and supplying water, which is converted to hydrogen and oxygen, with subsequent conversion of the carbon dioxide and hydrogen into alcohols is disclosed. The method includes, but is not limited to including, a direct air capture system carbon dioxide, a water electrolysis unit powered by electricity, a hydrogenation reactor to convert carbon dioxide and hydrogen gases into alcohols, and a distillation system to separate alcohols or a single constituent alcohol from other hydrogenation products. Optionally, these methods may include systems capture water from air, if water or hydrogen is not available on-site, and the distillation system may use propylene glycol as an extraction solvent. This process can be used for on-site production of feedstock alcohols such as ethanol at high purity, and many other applications.
