Polysulfide treated molecular sieves and use thereof to remove mercury from liquefied hydrocarbons
Patent
·
OSTI ID:5202151
This patent describes a process for preparing a molecular sieve absorbent. It comprises: drying a molecular sieve at a temperature of between about 350{degrees} and about 450{degrees} C in an anhydrous nonreactive atmosphere; contacting the molecular sieve with an aqueous solution of water soluble alkali polysulfide until the molecular sieve is saturated with the aqueous solution; and drying the saturated molecular sieve at a temperature between bout 10{degrees} and about 75{degrees} C and a pressure of less than about 500 millimeters of mercury to deposit the water soluble alkali polysulfide onto the molecular sieve without decomposing the water soluble alkali polysulfide.
