OXIDATIONAL SELF THERMAL REFORMING APPARATUS AND METHOD OF OXIDATIONAL SELF THERMAL REFORMING THEREWITH

摘要

Oxidational self thermal reforming apparatus (1) in that it includes reforming layer (2) having at least part thereof filled with a reforming catalyst, adapted to bring a mixture of hydrocarbon or aliphatic alcohol and steam into contact with the reforming catalyst to thereby produce a reformed gas composed mainly of hydrogen through reforming reaction, and oxidational exothermic layer (3) having at least part thereof filled with an oxidation catalyst, adapted to oxidize part of the reformed gas to thereby generate heat, and that the reforming layer (2) is disposed upstream of the oxidational exothermic layer (3), and that the reforming layer (2) and the oxidational exothermic layer (3) are cylindrical, and that the apparatus (1) has a triple circular tube structure composed of, disposed sequentially from radial-direction inside, inside reforming layer (2A), oxidational exothermic layer (3) and outside reforming layer (2B), and that at least part of the reforming catalyst incorporated in the inside reforming layer (2A) and outside reforming layer (2B) contains a Ru metal.
