ABSTRACT:
A regenerable molecular sieve comprises 0.001-15% elemental silver or gold in or on zeolite A. The molecular sieve is capable of simultaneously removing mercury and water from a fluid. A method for impregenating zeolite A with elemental silver or gold comprising treating the zeolite A with a solution of a silver or gold salt of a carboxylic acid and heating the impregnated zeolite A at a temperature sufficient to decompose the salt is also provided. A method for simultaneously and repeatedly removing mercury and water from a hydrocarbon fluid by contacting the fluid with an effective amount of a molecular sieve comprising zeolite A and 0.001-15% elemental silver or gold and regenerating the zeolite A at elevated temperatures is also provided.
