Process for producing mixture containing hydrogen gas.

摘要

A method of producing a gaseous mixture containing hydrogen gas by reacting a methane-rich gas composed mainly of lower hydrocarbons with steam under heat in a radiation heating device comprised of a heating zone (A), a zone (B) to be heated, a gas non-permeable boundary member (C) separating and defining these zones (A) and (B), a porous radiating member (D) having many gas-flowable pores in the heating zone (A) and a porous heat receiving member (E) having many gas-flowable pores in the heated zone, which comprises passing a high-temperature gas through the pores of the porous radiating member (D) from that side of the heating zone (A) which adjoins the gas non-permeable boundary member (C) to thereby heat the porous radiating member (D), using a porous heat receiving member (E) having a catalyst for said reaction under heat on the surfaces of gas-flowable pores as the porous heat receiving member (E) in the zone (B) to be heated, and passing steam and a methane-rich gas composed mainly of lower hydrocarbons through the pores of the porous heat receiving member from that side of the heated zone (B) which adjoins the gas non-permeable boundary member (C) to form a gaseous mixture containing hydrogen gas.
