Reforming hydrogen production reactor, conversion furnace, and reforming hydrogen production reaction method

Abstract

The present invention relates to a reforming hydrogen production reactor, a conversion furnace, and a reforming hydrogen production reaction method. According to the present invention, the reforming hydrogen production reactor and the conversion furnace adopt micro-catalytic reaction plates, wherein a catalytic active component is loaded on the reaction plate, such that the consumption of catalytic active metals is reduced, the catalyst is not easily subjected to carbon deposition deactivation, the diffusion distance of the reaction gas to the catalytic active center is shortened, the mass transfer resistance and the pressure drop of the reactor are reduced, and the conversion rate of the hydrogen production reaction is increased; the reaction gas flows outward from the center in the reactor, the flow channel area is gradually increased, and the temperature of the reaction plate is gradually increased, such that the conversion rate of the hydrogen production reaction as volume increaseand endothermic reaction is easily increased; the heat exchange zone is arranged in the reforming reactor, such that the temperature of the raw material gas entering the reaction zone is increased, the temperature of the product at the outlet of the reactor is reduced, the reaction rate is easily improved, and the material requirements on the downstream pipelines and equipment are easily reduced;and the reforming hydrogen production reactor has wide use range, and the furnace tube as the hydrogen production conversion furnace can be used for different types of conversion furnaces.

Description

technical field [0001] The disclosure relates to the field of reforming hydrogen production, and in particular, to a reforming hydrogen production reactor, a reformer, and a method for reforming hydrogen production reaction. Background technique [0002] Hydrogen is not only an important chemical raw material, but also a clean fuel. Hydrogen plays an increasingly important role in modern industry, especially petrochemical industry, fuel cell and other national economies. Under the multiple pressures of increasing crude oil quality and inferior quality in the world, increasing demand for clean oil products, continuously improving quality standards, and increasingly stringent environmental regulations, the demand for hydrogen is also increasing, and the demand for hydrogen production is also increasing. Devices also put forward higher requirements. [0003] Hydrogen production processes mainly include water electrolysis, light hydrocarbon steam reforming, partial oxidation a...

AI Technical Summary

Problems solved by technology

[0008] The existing hydrogen production conversion furnace is filled with a nickel-based catalyst of a certain particle size and shape in the furnace tube, which often causes uneven loading, causing the raw material gas to drift, resulting in a low conversion rate of the raw material, and the catalyst is prone to carbon deposition and deactivation. operating cycle

In addition, the catalyst with smaller particle size is loaded in the furnace tube, although it can increase the loading amount of the catalyst, increase the number of catalyst active centers, and improve the processing capacity and conversion rate of raw materials to a certain extent, the disadvantage is that the smaller the catalyst size, the furnace The larger the pipe pressure drop, the higher the energy consumption of the feed gas compressor
