Molecular-weight distributions for heavy fossil fuels from gel-permeation chromatography and characterization data

Conference ·
OSTI ID:6263424
; ; ;
A correlation is presented for calculating molecular-weight distributions for high-boiling hydrocarbon mixtures from measurements using gel-permeation chromatography (GPC). The correlation uses GPC elution volume, hydrogen-to-carbon ratio from elemental analysis, and hydrogen distribution from proton-NMR spectroscopy. The procedure is illustrated with results for an Alaskan North-Slope residue.
