2results about How to "High hydrogen yield" patented technology

This invention discloses an ethanol reforming hydrogen production device based on a photothermal-driven vapor phase reaction, comprising a shell, a support, a porous transport layer, a porous evaporation layer, and a porous catalyst layer. The porous transport layer is placed inside the shell, and the porous evaporation layer is placed on top of the porous transport layer. The support is located outside the porous transport layer and the porous evaporation layer, serving to support the porous catalyst layer and suspend it above the porous evaporation layer. The porous transport layer and the porous evaporation layer are made of SiO2, Ti4O7, and carbomer; the porous catalyst layer is made of SiO2, Ti4O7, carbomer, photothermal material Fe2O3, and catalyst Pt. This invention utilizes the photothermal effect of solar energy to locally generate heat at the reaction site, resulting in high hydrogen production, high product selectivity, and no CO2 emissions, making it suitable for efficient and green industrial hydrogen production.

The application provides a chemical chain reaction hydrogen production system and method. The system comprises a hydrocarbon conversion syngas reactor, a first gas-solid separation device, a syngas oxidation reactor, a second gas-solid separation device, a hydrogen production reactor and a third gas-solid separation device; the product outlet of the hydrocarbon conversion syngas reactor is connected with the feed inlet of the first gas-solid separation device, the gas phase product outlet of the first gas-solid separation device is connected with the gas feed inlet of the syngas oxidation reactor, the gas phase product outlet of the syngas oxidation reactor is connected with the feed inlet of the second gas-solid separation device, the solid phase product outlet of the syngas oxidation reactor is connected with the solid feed inlet of the hydrogen production reactor, and the product outlet of the hydrogen production reactor is connected with the feed inlet of the third gas-solid separation device. The technical scheme provided by the application can realize continuous methane efficient conversion, carbon dioxide capture and high hydrogen production rate and hydrogen purity.
