Description

Technical Field

[0001] The present invention relates to the technical field of hydrogen production, and in particular to a hydrogen production device and method for balanced use of catalysts. Background Art

[0002] As a secondary energy source, hydrogen energy is widely used in oil refining, electrochemistry, aerospace, metallurgy and other fields. At present, the steam methane reforming hydrogen production process is widely used.

[0003] For example, Chinese patent CN105680072B discloses a small- to medium-scale distributed natural gas steam reforming hydrogen production system, including an integrated natural gas steam reforming hydrogen production reactor body and a peripheral auxiliary system; the integrated natural gas steam reforming hydrogen production reactor body is composed of eight main components: a raw water evaporator, a natural gas preheater, a combustion chamber, a reforming chamber, a reforming gas cooler, a combustion flue gas waste heat cooler, a reforming gas waste heat cooler, and a fuel burner. A hydrogen production method for a small- to medium-scale distributed natural gas steam reforming hydrogen production system, wherein the raw natural gas and water are preheated in multiple stages and then enter the reforming chamber inside the integrated reactor for a steam reforming reaction. The energy utilization rationality and energy utilization efficiency of the entire system are improved; the reforming hydrogen production system is made efficient and compact; and the operation mode is highly selective, flexible and convenient.

[0004] However, the catalyst in the reforming chamber of the above-mentioned patent is used in a unidirectional direction, and the catalyst that contacts the gas first is consumed faster than the catalyst that contacts the gas later. When the catalyst that contacts the gas first is consumed completely, the catalyst that contacts the gas later is not completely consumed. When the overall catalyst is replaced according to the degree of consumption of the catalyst that contacts the gas first, the catalyst that contacts the gas later that is not completely consumed will also be replaced at the same time. This replacement method easily causes a waste of catalysts and is not conducive to full use of the catalyst.
