Abstract
The present disclosure provides a method of measuring a percent solids content (PSC) of solids by mass in a slurry catalyst composition, where the solids include a catalyst. The method includes obtaining a first time domain (TD)H-nuclear magnetic resonance (NMR) spectrum using a time domain (TD)-NMR spectrometer and a test sample of the slurry catalyst composition from which a value of a voltage signal (a) that represents the slurry catalyst composition is determined. A second TDH-NMR spectrum using the TD NMR spectrometer is obtained for a neat sample of the suspension liquid for the solids of the slurry catalyst composition, where a value of a voltage signal (b) from the second TDH-NMR spectrum that represents the suspension liquid for the solids of the slurry catalyst composition is determined. The percent solids content (PSC) of solids in a slurry catalyst composition is then determined with Equation I: PSC=(1−a/b×d/d)×100% Equation I where x represents mathematical multiplication, a and b are as described above, db is a density of the suspension liquid for the solids of the slurry catalyst composition and dis a density of the slurry catalyst composition.
