Products classified under HTS 3815.19.00.00
Zeolite-Supported Platinum Reforming Catalyst
This supported catalyst uses platinum on a zeolite base to facilitate hydrocarbon reforming reactions in petroleum refineries. It falls under HTS 3815.19.00.00 as a supported catalyst with precious metal not specified elsewhere in subheading 3815.12 or 3815.13.
Alumina-Supported Nickel Methanation Catalyst
Nickel dispersed on high-surface-area alumina serves as a catalyst for CO methanation in syngas processing. Classified under 3815.19.00.00 as a supported catalyst not qualifying for base metal subheadings due to specific preparation.
Silica-Supported Copper Dehydrogenation Catalyst
Copper oxide on silica gel accelerates dehydrogenation of alcohols to aldehydes in fine chemical production. This 'other' supported catalyst fits HTS 3815.19.00.00 as it doesn't meet precious or specific base metal criteria.
Zirconia-Supported Molybdenum Hydrodesulfurization Catalyst
MoS2 on zirconia promotes hydrodesulfurization removing sulfur from diesel fuel. Falls under 3815.19.00.00 as supported catalyst preparation NESOI with complex metal-support interaction.
Carbon-Supported Palladium Hydrogenation Catalyst
5% palladium on activated carbon facilitates selective hydrogenation of nitro compounds to amines. Classified 3815.19.00.00 as carbon is not a specified support triggering other subheadings.
Titania-Supported Vanadium SCR Catalyst
V2O5/WO3 on anatase titania reduces NOx emissions in selective catalytic reduction systems. HTS 3815.19.00.00 covers this supported preparation used in stationary emission control.
Magnesia-Supported Cobalt Fischer-Tropsch Catalyst
20% Co on MgO promotes syngas conversion to synthetic hydrocarbons via Fischer-Tropsch synthesis. This supported catalyst preparation is specified under 3815.19.00.00.
Ceria-Stabilized Alumina Three-Way Catalyst
CeO2-ZrO2 stabilized gamma-alumina with Pt/Rh/Pd promotes CO/HC/NOx conversion in automotive converters. Classified 3815.19.00.00 as complex supported preparation.
Zeolite-Supported Iron Ammonia Synthesis Catalyst
Promoted iron on zeolite support operates under high pressure/temperature for Haber-Bosch ammonia production. HTS 3815.19.00.00 as supported catalyst NESOI.
