  • Method and apparatus for analysis of alkylation catalyst composition
    Patent number: 9903810
    Abstract: Apparatus and method for the determination of weight fractions of hydrocarbons, water and acid in the acid catalyst phase of petroleum refinery alkylation catalyst streams by flowing the acid catalyst phase through a density detector and a spectrometer cell so that the determination can be made according to first principles. An alternative apparatus and method uses spectroscopy without the density detector.
