Latest Patents
One of Yao's latest patents is the "Thermally Desorbable Passive Dosimeter." This device features a structurally reinforced sorbent wafer designed to monitor a worker's exposure to ambient aromatics, including benzene, toluene, ethylbenzene, and xylenes. The wafer is created by pressing 4 mg of sorbent material between two pieces of 100 mesh stainless steel wire gauze, resulting in a thickness of about 1 mm. This design significantly reduces background noise during gas chromatographic analysis, enhancing the signal-to-noise ratio and allowing for the detection of lower concentrations of air contaminants compared to other passive dosimeters.
Another significant patent is the "Process for Removing Total Reduced Sulfur Compounds from Gaseous Stream." This process effectively removes Total Reduced Sulfur compounds from gaseous streams, such as those containing natural gas, industrial gas, and digester gas. It utilizes oxidation with a fine flocculent acidic catalyst slurry, which can be regenerated during the process by adjusting the pH without the need for added heat. The catalyst slurry consists of MnO.sub.2, Mn.sub.2 O.sub.3, and Mn.sub.3 O.sub.4, with a pH range of about 0.5 to 6.5, prepared by oxidizing a divalent manganous salt in an aqueous solution.
