Sulfur absorbents

A method of producing a zinc oxide based absorbent containing a regeneration aiding amount of molybdenum disulfide comprising the steps of:

• mixing molybdenum disulfide with zinc oxide and silica in an amount to provide a mixture comprising a regeneration aiding amount of molybdenum disulfide said amount ranging from at least a portion to about 25 parts by weight molybdenum disulfide per hundred parts by weight of the sum weight of zinc oxide, silica and molybdenum disulfide thereby forming a mixture also having extrusion die lubricating properties;
• adding to said mixture a dilute acid suitable for forming an extrudable paste from said mixture;
• and
• extruding said extrudable paste through an extrusion die to produce an extrudate of said zinc oxide based absorbent containing a regeneration aiding amount of molybdenum.

A method of preparing an absorbent having an improved ability to minimize sulfur slippage in a process for absorbing hydrogen sulfide from a fluid stream when contacted with said fluid stream in the presence of a small amount of hydrogen, comprising:

• mixing zinc oxide, silica, and at least some molybdenum disulfide up to about 25 parts by weight molybdenum disulfide per 100 parts by weight of the sum weight of zinc oxide, silica, and molybdenum disulfide to form a mixture;
• adding to said mixture a dilute acid suitable for forming an extrudable paste from said mixture;
• extruding said extrudable paste to produce an extrudate;
• and
• calcining said extrudate.
