Embodiment Construction

[0028] The following examples will further illustrate the present invention, but do not limit the present invention thereby.

[0029] Natural gas hydrogen production reactor of the present invention ( figure 1), which is composed of a number of different reaction chambers. The whole reactor body adopts a flat structure. From left to right, it includes material gasification (1a), catalytic combustion (1b), reforming (1c), pre-catalysis Multiple areas such as combustion (1d), material preheating (1e), transformation (1f), material preheating (1g) and purification (1h). The natural gas and water required for the hydrogen production reaction enter through the inlet (11), and are provided to the user through the outlet (14) after gasification, reforming, conversion and purification; the energy for the entire hydrogen production process comes from the catalysis of natural gas Combustion reaction, the raw material natural gas and air of the catalytic combustion reaction enter the hy...

Abstract

The invention relates to a natural gas hydrogen production reactor and a hydrogen production process thereof. The reactor is combined by a plurality of different reaction cavities, the whole reactor contains five reaction areas for reforming, catalytic combustion, pre-catalytic combustion, transformation and purification, as well as three areas for gasification of material, preheating of the material and the like, so that the compactness of the reactor is improved, the processing difficulty of the reactor is reduced and the reactor is easy for scaling up; and the flow way of material flows among the different reaction cavities is mainly based on parallel current and counter current, energy matching between internal different material flows is reasonable and the heat transfer efficiency is high. The reactor disclosed by the invention can be widely used for coupling reaction systems with strong heat release and strong heat absorption, in particular to hydrogen source systems of full battery distributed power supplies of 1-10kW.

Description

technical field [0001] The invention belongs to the technical field of hydrogen energy and fuel cells, and in particular relates to a natural gas hydrogen production reactor and a hydrogen production process thereof. Background technique [0002] my country is rich in natural gas resources, most of which are mainly distributed in remote areas such as the west and northwest, resulting in high costs for compression, transportation, storage, and utilization. At present, in order to realize the economic utilization of natural gas, natural gas is usually processed as the initial raw material to produce compounds such as multi-carbon hydrocarbons and alcohols, which is mainly completed in two steps: first, methane is converted into CO and H 2 (that is, synthesis gas), and then convert the synthesis gas into multi-carbon hydrocarbons and alcohol compounds, such as F-T synthesis. Synthesis gas can be prepared from almost carbon-containing compounds, such as coal, natural gas, etc. ...
