Comprehensive Guide to Mercury Removal Catalysts: Preventing Liquid Metal Embrittlement and CuS Chemisorption Guard Bed Operations
Trace elemental mercury in natural gas and liquid hydrocarbon streams causes catastrophic Liquid Metal Embrittlement (LME) in aluminum heat exchangers and irreversibly poisons noble metal catalysts. This technical guide unpacks the working mechanism of CuS/Al₂O₃ mercury removal catalysts, examining chemisorption kinetics, gas vs. liquid phase engineering, and safe guard bed operation to achieve rigorous sub-0.01 µg/m³ outlet purity.
A Comprehensive Guide to Methanation Catalysts: Reaction Mechanisms, Thermal Runaway, and Ammonia Synthesis Guard Bed Operation
Trace carbon monoxide (CO) and carbon dioxide (CO2) in synthesis gas act as lethal poisons to downstream ammonia and hydrogen catalysts. This technical guide explores the fundamental chemistry of nickel-based methanation catalysts, sulfur poisoning mechanisms, thermal runaway prevention, and guard bed engineering strategies to achieve sub-10 ppm carbon oxide purity.
