Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
We claim: 1. A dehydrogenation catalyst for use in dehydrogenation of a hydrocarbon gas, comprising platinum, an assistant metal, an alkali metal or alkaline earth metal, and a halogen component, which are supported on a carrier, wherein the carrier is alumina having a theta cryslallinity of 90% or more, and having mesopores of 5˜100 nm and macropores of 0.1˜20 μm, and having mesoporc volume of 0.32 -0.47 cc/g and macropore volume of 0.23-0.25 cc/g, and the platinum ha…
