  • Patent number: 11988654
    Abstract: A process for decreasing contamination of a commercial refining process by vanadyl porphyrins and/or nickel porphyrins by allowing rapid screening of porphyrins directly from asphaltenes isolated from crude oil without enrichment by use of positive-ion electrospray ionization mass spectrometry (ESI MS). Sodium formate is utilized as a ESI spray modifier. The vanadyl porphyrins are detected predominantly as sodiated species, while nickel porphyrins are observed as both sodiated species and molecular ions. Crude oil feedstocks exceeding a defined threshold concentration of vanadyl porphyrins and/or nickel porphyrins are rejected or diluted prior to utilization as refinery feedstock. Certain embodiments additionally quantitate both deoxophylloerythroetioporphyrins and etioporphyrin content (and their ratio) to predict crude oil thermal maturity.
