氯化汞触媒的汞挥发速率
Mercury evaporation rate of mercury chloride catalysts
摘要
Abstract
The mercury evaporation rate, specific surface area, catalyst composition, and mercury form of high-, low-, and waste high-mercury catalysts in the acetylene PVC industry were tested by the dynamic flux chamber, specific surface area analyzer, scanning electron microscopy and X-ray photoelectron spectroscopy, respectively. It is shown that the mercury evaporation rates of the high-, low-, and waste high-mercury catalysts are 1.04 x 10^-7, 5.90 x 10^-8, and 2.47 x 10^-4 mg · g^-1 ·min^-1 , respectively. Mercury chlo- ride is reduced to elemental mercury after the high-mercury catalyst is used, and mercury is adsorbed on the surface of the waste mercury catalyst, causing the mercury evaporation rate of the waste high-mercury chloride catalyst much higher than that of the new.关键词
