ConocoPhillips develops ZrO2 flue gas mercury sorbent

Mercury Uptake of Cross Sorbents

Mercury Uptake of Cross Sorbents

Joseph B. Cross of Bartlesville, Oklahoma and other inventors also from Oklahoma have developed a Vanadium on ZrO2 sorbent and have shown that sorbent to have significant advantages over sulfur impregnated activated charcoal.  Their work was awarded US Patent No. 7,767,002 entitled “Mercury Removal Sorbent.”  The patent discusses several advantages of the invention including an ability to maintain the mercury in a sequestered form and the potential ability to regenerate the sorbent at high temperatures. Patent Office records show that the invention is owned by ConocoPhillips Company of Houston Texas.  If the effectiveness of the sorbent is enough to overcome the higher costs of materials and sorbent production costs, the invention disclosed in the patent may see commercial use as a mercury capture and storage system or more likely a recycling/regenerative mercury removal system.
