TD-NMR Analysis of Catalytic Cracker Feedstocks
The 19.5 MHz Spintrack NMR analyzer was utilized to study a large series of vacuum gas oils and FCC feeds for which PNA also has laboratory test data.
The analysis was performed on a SpinTrack 19.5 MHz TD-NMR spectrometer - CPMG T2 decays were generated and then that data was processed with a inverse laplace transformation to produce T2 distribution profiles. These T2 distribution profiles are currently being correlated to physical and chemical property data.
NMR Experiment explanation is given below: |
