  • Butanol Purification
    Publication number: 20180016215
    Abstract: Provided are methods for removing one or more components from a butanol based composition. The methods comprise providing a butanol based composition comprising one or more components, targeting at least one component or a combination thereof for reduction, and processing said butanol based composition such that the at least one targeted component is substantially removed. The butanol based composition can, for example, be bio-produced.
    Type: Application

  • Process for the acid-catalysed dehydration of ethanol
    Patent number: 9828319
    Abstract: A process for the acid-catalyzed dehydration of ethanol, the process comprising the steps of distilling an ethanol feedstock (101) comprising at least one nitrogen-containing contaminant to form an overhead stream (102) and a bottom stream comprising ethanol (103), wherein the distillation has a reflux ratio of at least 20:1; and reacting the bottom stream in the presence of an acid catalyst to form a product stream comprising ethylene.
    Type: Grant

  • Treatment of alcohols
    Patent number: 9725387
    Abstract: Process for treating an alcohol composition containing nitrogen-containing contaminants by contacting the alcohol composition with an adsorbent in an adsorption zone. The adsorbent is a transition metal-loaded solid porous material selected from aluminosilicates, silica-aluminas, silicates and aluminas, and the alcohol composition is contacted with the adsorbent either alone or in the presence of an inert carrier gas.
