Hydrogen production reactor using honeycomb SiC ceramic as catalyst carrier

Abstract

The invention discloses a hydrogen production reactor taking honeycomb SiC ceramic as a catalyst carrier. The reactor comprises an upper cover plate, a lower cover plate, an evaporation plate, a firstcatalytic combustion plate, a second catalytic combustion plate, a reforming chamber upper cover plate, a methanol steam reforming plate and a reforming chamber lower cover plate. Bolts pass througheach plate and are tightly connected; the upper and lower cover plates are provided with reactant inlet and outlet pipes; the evaporation plate is provided with a serpentine flow passage as an evaporation chamber; the first and second catalytic combustion plates are provided with parallelogram grooves as combustion chambers; the reforming chamber upper cover plate and the methanol steam reformingplate are provided with rounded rectangular through grooves, wherein the honeycomb SiC ceramics are arranged; reactants alternately pass through each plate and flow into corresponding cavities/groovesto realize hydrogen production reaction. The hydrogen production reactor can improve the orientation and flow uniformity of fluid flow, has the characteristics of high thermal conductivity, good thermal stability, stable chemical performance, large specific surface area and the like, improves the mass transfer and heat transfer performance in the reactor, reduces the pressure loss in the reactor,and enhances the loading capacity of a catalyst.

Description

technical field [0001] The invention relates to a methanol reforming hydrogen production reactor, in particular to a hydrogen production reactor using honeycomb SiC ceramics as a catalyst carrier. Background technique [0002] With the continuous development of society, the human demand for petroleum fossil fuels continues to increase. However, the extensive use of fossil fuels has led to serious environmental pollution and global warming. At the same time, the reserves of fossil fuels are limited, so the search for renewable green energy has become a hot research topic today. Hydrogen energy has the characteristics of renewable, high utilization rate and wide range of sources, and is an ideal energy source to replace fossil fuels. [0003] Hydrogen fuel cells are one of the main ways to utilize hydrogen energy. At present, the application of hydrogen fuel cells in mobile applications is severely restricted by the development of mobile hydrogen supply technology. As a hyd...
