Abstract
Official abstract text for this publication.
Processes for contacting an olefin feed stream, preferably comprising ethylene, with at least one stream from an ethanol production process that comprises water. The hydration reaction produces ethanol to improve overall ethanol yields from the hydrogenation acetic acid and esters thereof.
First claim
Opening claim text (preview).
What is claimed is: 1. A process for producing an alcohol, comprising: hydrogenating an acetic acid feed stream in the presence of a first catalyst in a first reaction zone to form a crude alcohol product; separating at least a portion of the crude alcohol product in one or more columns to produce an alcohol product stream and a dilute alcohol stream comprising water; and contacting an olefin feed stream with at least a portion of the dilute alcohol stream in the presence of a…
