Reforming hydrogen production reactor and its reformer and method for reforming hydrogen production reaction

Abstract

The present disclosure relates to a reforming hydrogen production reactor and its reformer, and a method for reforming hydrogen production. The amount of catalytically active metal is reduced, the catalyst is not easy to be deactivated by carbon deposition, the distance from 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 improved; It flows from the center to the outside, the flow channel area gradually increases, and the temperature of the reaction plate gradually increases, which is beneficial to the improvement of the conversion rate of the hydrogen production reaction as a volume increase and an endothermic reaction; the reforming hydrogen production reactor has a wide range of applications. As the furnace tube of the hydrogen reformer, it can be applied to different types of reformers. The hydrogen production method using the reforming hydrogen production reformer reduces the furnace tube pressure, the product space-time yield per unit volume of the catalyst in the furnace tube is high, and the raw gas processing capacity can be converted, and the hydrogen production reaction requirements can be met.

Description

technical field [0001] The present disclosure relates to the field of reforming hydrogen production, in particular, to a reforming hydrogen production reactor and its 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 ox...

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
