Carbon isotope analyses of n-alkanes released from rapid pyrolysis of oil asphaltenes in a closed system

摘要

RationaleCarbon isotope analysis of n-alkanes produced by the pyrolysis of oil asphaltenes is a useful tool for characterizing and correlating oil sources. Low-temperature (320-350 degrees C) pyrolysis lasting 2-3days is usually employed in such studies. Establishing a rapid pyrolysis method is necessary to reduce the time taken for the pretreatment process in isotope analyses.
