The 19.5 MHz Spintrack NMR analyzer was utilized to study a FAME biodiesel production reaction. The samples analyzed were:
1) Used vegetable oil
2) Partially transesterified biodiesel product (bad biodiesel)
3) High yield FAME biodiesel product
4) Glycerin by-product from the process
CPMG T2 decays were generated and then that data was processed with a inverse laplace transformation to produce T2 distribution profiles.
NMR Experiment explanation is given below:
The CPMG data obtained on the four samples is shown below:
The T2 distribution profiles obtained by inverse Laplace transformation of the CPMG data are shown below:
Plainly TD-NMR can play a role in monitoring the biodiesel production process.
