Molecular composition of vanadyl porphyrins in the gilsonite

Journal of Fuel Chemistry and Technology, 2020
Abstract A gilsonite from Qingchuan (Sichuan province, China) was separated into several fractions and characterized by various techniques. The vanadyl porphyrins were determined by inductively coupled plasma optical emission spectrometer, ultraviolet-visible spectrophotometry, high-temperature gas chromatography-atomic emission detector, and ...

Thermal stability of the asphaltene/kerogen vanadyl porphyrins

Organic Geochemistry, 1996
Abstract Thermal stability of vanadyl porphyrins incorporated into the asphaltene/kerogen structures of the Dead Sea asphalt “float”, the La Luna Mara limestone and the Serpiano marl was studied by electron spin resonance (ESR). Comparative studies were also made on alkyl vanadyl porphyrins such as deoxophylloerythroetioporphyrins and (extracted and ...

Incorporation of vanadyl porphyrins into kerogen structures during catagenesis

Fuel, 2000
Natural vanadyl (VO 21 )‐deoxophylloerythroetioporphyrins (DPEP) are shown to be capable of reacting and quantitatively incorporating into the immature kerogen model materials (torbanite, lignites, subbituminous coal and an immature lacustrine kerogen) at 2008C for 72 h in the absence/presence of air oxygen.

Are vanadyl porphyrins products of asphaltene/kerogen thermal breakdown?

Fuel, 1997
The idea was examined that during early stages of thermal maturation of source rocks or petroleums, the release of bound vanadyl (VO2+) porphyrins (P) from the immature asphaltenes or kerogen could contribute to an increase in extractable VO2+-P. To simulate such a change in the laboratory, the Dead Sea ‘floating’ asphalt and total organic (bitumen ...

Estimation of vanadyl porphyrin concentration in sedimentary kerogens and asphaltenes

Fuel, 2000
We describe a new, rapid method for determining the concentration of vanadyl porphyrins (VO2+-P) associated with the kerogen of bituminous sedimentary rocks using electron spin resonance (ESR). The method is simple, straightforward and inexpensive. Several concentrations of a vanadyl (VO2+) standard dissolved in glycerol-lignite mixture were prepared ...
