  • Patent number: 5202517
    Abstract: An apparatus and system for the dehydrogenation of ethane to produce ethylene and hydrogen through the use of a catalytic ceramic membrane having selective permeability, thus permitting separation of hydrogen from the reaction zone which causes further dehydrogenation of ethane, the catalytic ceramic membrane being in a cylindrical form which has been treated to have a metallic catalyst of suitable metal, such as platinum, palladium or chromium, deposited on the surface adjacent to the reaction zone. The catalytic ceramic membrane tube is enclosed within an alloy tube of suitable composition to permit heating to the temperature range of to C. The annulus surrounding the ceramic membrane tube may be filled with a pelleted catalyst, thus causing the dehydrogenation reaction to take place within this annular zone, but which will be accelerated by the permeation of hydrogen out of the zone through the ceramic catalytic membrane.
