Non-noble metal methanol-to-hydrogen catalyst requiring no reduction and preparation method thereof

Abstract

The invention discloses a non-noble metal methanol-to-hydrogen catalyst requiring no reduction and a preparation method thereof. The active component of the catalyst is NiO, and the mass ratio of the NiO is 1-30%; the auxiliaries of the catalyst are ZnO and CeO2, and the mass ratio of the auxiliaries is 8-55%; the carrier of the catalyst is at least one selected from aluminum oxide, zirconium oxide, titanium oxide and cordierite, and the mass ratio of the carrier is 15-91%. The dispersion degree and the stability of the catalyst are improved through a method of dipping twice. The catalyst provided by the invention can be applied to high-temperature steam reforming of methanol for hydrogen production under a reaction condition of 350-600 DEG C; and a noble metal catalyst and a copper-based catalyst are not used, reaction is good at high temperature, the catalyst does not need to be reduced before the reaction, reduction cost is saved, time is saved, and operation is simpler.

Description

technical field [0001] The invention relates to the technical field of new energy, in particular to a non-precious metal methanol hydrogen production catalyst without reduction and a preparation method thereof. Background technique [0002] With the development of fuel cell research in recent years, the preparation of fuel, including hydrogen production, purification and storage, has also received extensive attention. Methanol has the advantages of cheap and easy to obtain, high energy density, low carbon content, and convenient transportation and storage. It is known as the most promising high-energy-carrying fuel. There are three kinds of partial oxidation reforming, among which hydrogen production by steam reforming of methanol is the reaction with the highest hydrogen content in the reformed gas, which has the advantages of low cost, mild conditions, less product components and easy separation. [0003] The core of methanol steam reforming hydrogen production technology...
