Abstract:
An enhanced, surface modified activated carbon for filter media, having a higher capacity for removing specific contaminants, such as H 2 S, SO 2 , Cl 2 , CCl 4 , NH 3 , and HCHO, and a process for making the same. The surface of the activated carbon is modified with molybdenum and molybdenum-derivatives to enhance the activated carbon chemisorption capacity.

Claim (Index 15):
A process for increasing the adsorption performance of activated carbon comprising:\n treating said activated carbon with an oxidizing agent to form treated carbon, said treating including: soaking said activated carbon in sulfuric acid solution while stirring; decanting said activated carbon in said sulfuric acid solution; drying said activated carbon at low temperature; impregnating said treated carbon with molybdenum, said impregnating including: preparing an ammonium molybdate precursor solution; soaking said treated carbon in said precursor solution to form a molybdenum-loaded treated carbon; decanting said molybdenum-loaded treated carbon; drying said molybdenum-loaded treated carbon at low temperature; heating said molybdenum-loaded treated carbon under a nitrogen gas flow to a temperature of approximately 500\u00b0 C. for about three hours to form a resultant activated carbon having a surface impregnated with molybdenum and molybdenum-oxides, such that a metal complex is formed among oxygen and sulfur functional groups and said molybdenum and molybdenum-oxides; and, allowing said molybdenum-loaded treated carbon to cool prior to use.
