Catalyst for hydrogen production by methanol steam reforming, preparation method and application thereof, and reaction for hydrogen production by methanol steam reforming

Abstract

The invention belongs to the technical field of energy and chemical industry, and provides a catalyst for hydrogen production by methanol steam reforming, a preparation method and application thereof, and a reaction for hydrogen production by methanol steam reforming. The catalyst provided by the invention comprises an oxide carrier, and a copper oxide and fullerene C60 which are loaded on the oxide carrier. The fullerene C60 has excellent electron acceptor properties, can reversibly capture and release electrons, can effectively adjust the electrons on the copper surface, and controls the equilibrium distribution and stability of the copper valence state, thereby ensuring the stability of the catalyst. According to the catalyst provided by the invention, under the conditions that the temperature is 240 DEG C, the pressure is 0.1 MPa, the molar ratio of water to methanol is 1.2: 1, and the mass space velocity of methanol is 4.5 h <-1 >, the hydrogen production rate is 0.4 mol / g / h, the CO selectivity is lower than 0.3%, the structure and performance are kept stable after continuous reaction for 200 h, and the inactivation phenomenon does not occur.
