Abstract

This work presents a dataset which provides information on the influence of aromatic nuclei on the carbon isotope of gases. Gases analyzed herein were obtained by pyrolysis of model compounds and kerogens. The carbon isotope of gases from paraffin cracking with and without the addition of aromatic nuclei is summarized. We also obtained carbon isotope data for the gases from different type of kerogens, which indicate the role of aromatic nuclei in the formation of natural gases from kerogen cracking. Further interpretation and discussion of these data can be found in the related research article entitled "The methylation of aromatic nuclei - I: Implications for the geochemical evolution of gas" [1].

Keywords: Aromatic nuclei; Carbon isotope; Natural gas; Pyrolysis experiment.
