Alumina-Supported Nickel Methanation Catalyst
Alumina-supported nickel methanation catalyst used in syngas processing to convert carbon monoxide and hydrogen into methane. The nickel active phase is dispersed on a high-surface-area alumina support, making it a supported catalyst preparation. It is classified under this tariff item as a supported catalyst not elsewhere specified or included.
Carbon-Supported Palladium Hydrogenation Catalyst
Carbon-supported palladium hydrogenation catalyst with 5% palladium on activated carbon, used for selective hydrogenation of nitro compounds to amines. The carbon support is not a specified support material in other subheadings, so this falls under the 'other' supported catalyst category. It is classified under this tariff item as a supported catalyst not elsewhere specified or included.
