Abstract:
A reformer tube assembly for use in reformer reactors including a ceramic tube having an open top end and a closed bottom end, a corrosive resistant liner for the ceramic tube also having an open top end and closed bottom end and a centrally disposed metal tube having an open top end and open bottom end wherein the centrally disposed metal tube has a diameter substantially less than the liner so as to form an annulus between the interior of the liner and the exterior of the centrally disposed tube in which catalyst for the reaction is placed, and the open bottom end of the centrally disposed tube is spaced away from the closed bottom of the liner to allow process gas exiting the catalyst filled annulus to pass along the closed bottom of the liner and up the interior of the centrally disposed metal tube.
