Abstract
A catalyst used for dehydrogenation of an organic hydrogen-storage material to generate hydrogen, a support for the catalyst, and a preparation process thereof are presented. A hydrogen-storage alloy and a preparation process thereof are provided. A process for providing high-purity hydrogen, a high-efficiently distributed process for producing high-purity and high-pressure hydrogen, a system for providing high-purity and high-pressure hydrogen, a mobile hydrogen supply system, and a distributed hydrogen supply apparatus are also described.
Claims12
A support composition for a dehydrogenation catalyst of an organic substance, comprising an alumina substrate and a modifying metal oxide disposed thereon, wherein:
- the modifying metal oxide is titanium oxide or a combination of titanium oxide and zirconium oxide,
- η<0.3, η being the content by weight percent of the crystal phase of the modifying metal oxide in the support composition/the content by weight percent of the chemical composition of the modifying metal oxide in the support composition, and
- θ≥5, θ being the content by weight percent of the modifying metal oxide on the surface of the support composition/the content by weight percent of the chemical composition of the modifying metal oxide in the support composition, titanium oxide is calculated as TiO2, zirconium oxide is calculated as ZrO2,
- wherein the modifying metal oxide is formed by contacting a modifying metal oxide precursor in a ads phase with the alumina substrate to form an alumina substrate loaded with the modifying metal oxide precursor, followed by hydrolyzing and calcining the alumina substrate loaded with the modifying metal oxide precursor to convert the modifying metal oxide precursor to the modifying metal oxide.
