Abstract

The invention relates to a Ba-Mn perovskite type cobalt-based catalyst for hydrogen production by autothermal reforming of acetic acid. Aiming at the problem that an existing catalyst is inactivated in the acetic acid autothermal reforming process, the invention provides a novel catalyst with a stable structure and high activity. The molar composition of the catalyst is (BaO)a(MnO1.5)b(CoO1.5)c interms of oxides, wherein a is 0.177-0.430, b is 0.430-0.709, and c is 0.113-0.140; the catalyst is composed of the components in percentage by weight based on oxides: 30.4 to 60.4 percent of barium oxide, 29.5 to 59.6 percent of manganese oxide and 8.0 to 11.0 percent of cobalt oxide. A sol-gel method is adopted for preparation; cobalt is used as an active component, manganese and barium are introduced, and a stable BaMn0.7Co0.3O2.8 and BaMnO3 perovskite structure composite oxide structure is formed after roasting, so that the oxidation resistance and dispersity of active components are improved, and meanwhile, the hydrogen yield, sintering resistance and carbon deposition resistance in the acetic acid autothermal reforming process are improved.

Description

technical field

[0001] The invention relates to the application of a Ba-Mn perovskite-type cobalt-based catalyst in the production of hydrogen by autothermal reforming of acetic acid, belonging to the field of producing hydrogen by autothermal reforming of acetic acid. Background technique

[0002] With the rapid development of human society and economy, the demand for energy continues to increase. Finding alternative energy sources to traditional fossil fuels has become an urgent goal in today's world, and hydrogen is a clean source of energy. Traditional hydrogen production methods mainly include oil catalytic cracking, natural gas reforming, and electrolysis of water to produce hydrogen. Hydrogen production by electrolysis of water is costly, while hydrogen production from oil and natural gas needs to consume a large amount of non-renewable resources. Therefore, in order to realize the long-term and efficient utilization of hydrogen energy, the primary problem to be solv...
