摘要： 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.

摘要： The present invention provides a process for the preparation of ethene by vapor phase chemical dehydration of a feed-stream comprising ethanol and optionally water and/or ethoxy ethane, said process comprising contacting a dried supported heteropolyacid catalyst in a reactor with the feed-stream having a feed temperature of at least 200° C.; wherein before the supported heteropolyacid catalyst is contacted with the feed-stream having a feed temperature of at least 200° C., the process is initiated by: (i) drying a supported heteropolyacid catalyst in a reactor under a stream of inert gas having a feed temperature of from above 100° C. to 200° C.; and (ii) contacting the dried supported heteropolyacid catalyst with an ethanol-containing vapor stream having a feed temperature of from above 100° C. to 160° C.

摘要： The present invention provides a process for the preparation of ethene by vapor phase chemical dehydration of a feed comprising ethanol and optionally water and/or ethoxyethane, said process comprising contacting a dried supported heteropoly acid catalyst in a reactor with the feed-stream having feed temperature of at least 200° C.; wherein the pressure inside the reactor is at least 0.80 MPa but less than 1.80 MPa; and before the supported heteropolyacid catalyst is contacted with the feed-stream having a feed temperature of at least 200° C., the process is initiated by: (i) drying a supported heteropolyacid catalyst in a reactor under a stream of inert gas having a feed temperature of from above 100° C. to 200° C.; and (ii) contacting the dried supported heteropolyacid catalyst with an ethanol-containing vapor stream having a feed temperature of from above 100° C. to 160° C.
