Methods, apparatuses, and systems for conversion of bioethanol to renewable jet fuel

Abstract

Methods, apparatuses, and systems for the conversion of bioethanol to renewable jet fuel are disclosed. In an example embodiment, a method for converting bioethanol to renewable jet fuel includes providing an olefin process stream comprising olefins to a hydrogenation reaction zone, converting at least a portion of the olefin process stream to a product stream comprising jet-range compatible hydrocarbons, determining, in the hydrogenation reaction zone, an iso-to-normal ratio of a portion of the product stream via one or more online analyzers, in an instance wherein the determined iso-to-normal ratio fails to satisfy a predetermined iso-to-normal threshold ratio, determine at least one additive and an amount of the at least one additive to be added to the product stream, the at least one additive configured to adjust a freeze point of the product stream, and adding the at least one additive to the product stream prior to the product stream exiting the hydrogenation reaction zone.

Dependencies are inferred from the claim text.
