  • Process for preparing ethene
    Patent number: 9950968
    Abstract: The present invention provides a process for the preparation of ethene by vapor phase chemical dehydration of a feed comprising ethanol, said process comprising contacting the feed with a supported heteropolyacid catalyst in a reactor, wherein the feed temperature is at least 250° C. and the pressure inside the reactor is at least 0.80 MPa but less than 1.80 MPa.
    Type: Grant
    Filed: April 1, 2015
    Date of Patent: April 24, 2018
    Assignee: Technip E&C Limited
    Inventors: Stephen Roy Partington, Nigel Stewart Brown, Michael Keith Lee, Mark Julian Howard
  • 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
