Abstract

The invention provides a fluidized bed reactor. A reaction area of the reactor is provided with foam metal plates with catalytic activity, the foam metal plates are longitudinally and / or transversely arranged along the reaction area, the space among the foam metal plates and / or the space between the foam metal plates with the inner wall of the reaction area are / is used to hold a fluidizable particle, and the fluidizable particle can pass through pores on the transversely-arranged foam metal plates. The invention also provides a fluidized bed reaction apparatus which comprises the fluidized bed reactor and a regenerator. The invention also provides a methane water-vapour reforming method using the fluidized bed reaction apparatus, and the foam metal plates have catalytic activity on the methane water-vapour reforming reaction, and at least a part of the fluidizable particle has adsorption effect on carbon dioxide. In the method, the catalyst does not need frequently regenerating along with the adsorbent, when the adsorbent is guaranteed to be always capable of satisfying usage requirements, energy consumption during regeneration is reduced, and senseless reduction of the catalyst activity is avoided.

Description

technical field [0001] The invention relates to a fluidized bed reactor, and also relates to a fluidized bed reaction device using the fluidized bed reactor, and further relates to a methane steam reforming method. Background technique [0002] With the development of economy and society, the demand for energy is gradually increasing; however, oil resources are becoming increasingly depleted and environmental pollution is becoming more and more serious, so the development and utilization of clean energy has become a research hotspot. Hydrogen not only has a high calorific value of combustion, but also has no adverse effects on the environment because the combustion product is water, so it is an efficient and ideal clean energy. [0003] Hydrogen can be produced from methane (that is, natural gas) through steam reforming, and natural gas reserves are abundant worldwide. Therefore, the development and utilization of hydrogen energy has gradually attracted attention. [0004] ...
