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

Abstract

The disclosure relates to a reforming hydrogen production reactor, a hydrogen production conversion furnace and a hydrogen production reaction method. The reforming hydrogen production reactor and the conversion furnace adopt a micro-catalytic reaction plate, and the activity required for the hydrogen production reaction is loaded on the reaction plate Components, reducing the amount of catalytically active metals and the catalyst is not easy to be deactivated by carbon deposition, shortening the distance from the reaction gas to the catalytic active center, reducing the mass transfer resistance and reactor pressure drop, and improving the conversion rate of the hydrogen production reaction; the reaction gas Flowing from the center to the outside in the reactor, the flow channel area gradually increases, and the temperature of the reaction plate gradually increases, which is conducive to the improvement of the conversion rate of the hydrogen production reaction as a volume increase and endothermic reaction; the reforming hydrogen production reactor uses Wide range, as the furnace tube of the hydrogen production reformer, it can be applied to different types of reformer. The hydrogen production method using the reforming hydrogen production conversion furnace has a lower pressure of the furnace tube, a high time-space yield of the catalyst per unit volume in the furnace tube, and a high conversion rate of the raw material gas treatment capacity, which can meet the requirements of the hydrogen production reaction.

Description

technical field [0001] The present disclosure relates to the field of reforming hydrogen production, in particular, to a reforming hydrogen production reactor, a hydrogen production conversion furnace and a hydrogen production reaction method. 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, ...

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
