Problems solved by technology

But the reaction is not complete, and the content of by-products is more
Researchers have improved the reactor device and used various new reactors such as three-stage type to increase the activity of the catalyst and improve the service life of the catalyst. However, the catalytic effect achieved through the modification of the reactor and its relationship with the catalyst The synergistic effect between them is not ideal, and there are still many disadvantages, which restrict the industrial application of ethanol reforming hydrogen production technology

Abstract

The invention relates to a microreactor applied to an ethyl alcohol and water vapor reforming reaction and a preparing method of the microreactor. The microreactor comprises spherical cerium dioxide and a Beta molecular sieve shell structure with the inner wall loaded with platinum, and an isolation hollow structure is arranged between spherical cerium dioxide and the Beta molecular sieve shell structure. The preparing method comprises the steps that a platinum source, an aldehyde compound, a phenol compound, a cerium source, polyvinylpyrrolidone, deionized water, absolute ethyl alcohol and the like serve as raw materials, poly diallyldimethylammonium chloride and sodium polystyrene sulfonate serve as treating agents, spherical cerium dioxide is synthesized first and then coated with phenol resin layers, high-temperature carbonization is carried out under the nitrogen condition, then spherical cerium dioxide coated with the phenol resin layers is treated with the treating agents, and finally the jingle-bell-type microreactor is synthesized. The jingle-bell-type microreactor applied to the ethyl alcohol and water vapor reforming reaction is simple, fast and controllable; according to the jingle-bell-type microreactor prepared through the method, the grain diameter ranges from 1.5 micrometers to 2 micrometers, and the product purity reaches 99.9%.

Description

technical field [0001] The invention relates to a microreactor, in particular to a microreactor applied to ethanol steam reforming reaction and a preparation method thereof. Background technique [0002] Hydrogen energy has become one of the most ideal low-carbon energy sources in the world today. There are many hydrogen production technologies that have been developed and utilized. However, from the long-term perspective of sustainable development, the bioethanol steam reforming reaction has a good application prospect for hydrogen production. Its advantage is that the whole process from biological fermentation to ethanol hydrogen production can form a carbon cycle system without net carbon dioxide emissions. [0003] The hydrogen production performance of the ethanol steam reforming reaction is mainly affected by the catalyst and the reactor. At present, research on catalysts is mainly focused on supported active component catalysts. This type of catalyst combines the adv...
