Dehydrogenation catalyst

摘要

This invention relates to a dehydrogenation catalyst having a macropore size and a high active density of platinum, suitable for use in dehydrogenation of a hydrocarbon gas. This dehydrogenation catalyst having a macropore size and a high active density of platinum is highly active, has high active density per unit catalytic surface area, facilitates material transfer of reactants and products, delays deactivation due to coke formation, keeps the initial activity constant after being regenerated thanks to the disposal of coke, has high strength and so is resistant to external impact, and undergoes neither structural changes due to heat nor changes in the properties of active materials.
