PROCESS FOR THE ACID-CATALYSED DEHYDRATION OF ETHANOL

A process for the acid-catalysed 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 ref...

Summary:A process for the acid-catalysed 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. Cette invention concerne un procédé de déshydratation de l'éthanol catalysé par un acide, le procédé comprenant les étapes consistant à distiller une charge d'éthanol (101) comprenant au moins un contaminant contenant de l'azote pour former un flux de tête (102) et un flux de queues comprenant l'éthanol (103), la distillation ayant un taux de reflux d'au moins 20:1 ; et à faire réagir le flux de queues en présence d'un catalyseur acide pour former un flux de produit contenant l'éthylène.
