Abstract

The invention relates to a method for producing hydrogen by reforming methane and hydrogen sulfide. According to the method, hydrogen sulfide, methane and a catalyst are subjected to a contact reaction, wherein the catalyst comprises, by mass, 5-65% of Fe2O3, 1-20% of Co2O3, and 15-94% of LaMO3, LaMO3 is a carrier having a perovskite structure, and M is at least one selected from Co, Fe and Ni. According to the present invention, the perovskite type oxide is used as the carrier, and supports Fe2O3 and Co2O3 as the active components, wherein the perovskite type oxide has good stability at a high temperature, is suitable for high temperature reactions, and is rich in oxygen vacancies and lattice oxygen so as to easily activate methane and hydrogen sulfide, and Fe2O3 and Co2O3 are used as thedouble active components so as to effectively improve the conversion rates of methane and hydrogen sulfide and lower the reaction temperature, such that the reaction is performed at the relatively low temperatures, the reactants have high conversion rates, and the energy consumption is reduced.

Description

technical field

[0001] The invention relates to a method for producing hydrogen by reforming methane hydrogen sulfide, in particular to using a catalyst with a perovskite structure to catalyze the reforming of methane hydrogen sulfide, which belongs to the catalyst technology in the field of methane reforming hydrogen production. Background technique

[0002] The main form of sulfur in natural gas is H 2 S, and the rest are organic sulfur such as mercaptans and sulfides, which will also be converted into H through hydrogenation 2 S. h 2 S is a highly toxic, foul-smelling, and highly corrosive gas. Therefore, sulfur-containing natural gas will cause a series of complicated problems in drilling, gas production, and gas transmission. Corrosion, resulting in huge economic losses. Therefore, proper disposal or utilization of H 2 S is also a severe problem faced by my country's petrochemical industry.

[0003] Currently, my country's H 2 The S utilization technology is also...
