  • Measurement of chloride content in catalysts
    Patent number: 11499930
    Abstract: Embodiments provide a method for determining a chloride content of an alumina-based catalyst used for catalytic reforming. The method includes the step of combining nitric acid, isopropanol, and the alumina-based catalyst such that the alumina-based catalyst is dissolved in the nitric acid and the isopropanol to form a homogenized mixture. The alumina-based catalyst include chloride. The method includes the step of taking a conductivity measurement of the homogenized mixture using a pair of electrodes. The method includes the step of introducing a titrant solution comprising silver nitrate to the homogenized mixture such that a precipitate of silver chloride is formed. The method includes the step of determining a chloride concentration of the homogenized mixture based on the conductivity measurement of the homogenized mixture. The method includes the step of determining the chloride content of the alumina-based catalyst based on the chloride concentration of the homogenized mixture.
