| titleOfInvention | Catalyst for steam methane reforming having an active metal concentration gradient in an spinel structured inorganic oxide support, a method for preparing the same, and a method for preparing a synthesis gas using the catalyst |
| abstract | The present invention relates to a method for preparing a catalyst applied to an SMR reactor for a hydrogen charging station into a catalyst having excellent thermal stability and strong resistance to carbon deposition. Since the catalyst for SMR reaction requires the pellet catalyst to have high thermal stability in order to maintain a high reaction temperature, pellets made of inorganic oxide having excellent thermal stability and having a spinel structure were selected as the catalyst support. The SMR reaction exhibits a very high reaction rate compared to the diffusion rate of the reactant, so that most of the reaction occurs on the surface of the pellet, making it difficult to effectively use the active metal. In order to solve this problem, in the present invention, a catalyst having a concentration gradient in which the active metal is selectively supported only on the outer surface of the pellet was prepared. For reactivity comparison, a catalyst without a concentration gradient in which the active metal is evenly supported throughout the pellet was also prepared. As a result, the catalyst with the concentration gradient showed that the durability of the pellets and the degree of carbon deposition in the SMR reaction under severe conditions were superior to the catalyst without the concentration gradient and the commercial catalyst. It was confirmed that the catalyst with a concentration gradient is more suitable for the SMR reaction. |
