Composition of the Thermal Cracking Products of Resins, Asphaltenes, and Their Mixture Using Methane Crude Oil as an Example

The influence of the duration of thermal action on the composition of cracking products of resins, asphaltenes, and their mixtures isolated from methane heavy crude oil of Zyuzeevskoye oil field was studied. Cracking was performed in a closed reactor at 450^оС for 60, 90, and 120 min. Data on the mass balance of the process and the composition of hydrocarbons and sulfur-containing compounds in the cracking products were obtained. It was shown that the yield of coke increased with the process duration in the cracking of every studied material. The joint presence of resins and asphaltenes in a mixture changed the direction of thermal transformations of these components in the cracking process.
