Reaction kinetics of stable carbon isotopes in natural gas-insights from dry, open system pyrolysis experiments
TL;DR: Open system nonisothermal pyrolysis with on-line compound-specific 13C/12C stable isotope analysis (Py-GC/IRMS) has been performed on three carbonaceous sediments from NW Germany as mentioned in this paper.

Natural gas formation in the western Nile delta (Eastern Mediterranean): Thermogenic versus microbial ☆
TL;DR: In this paper, a regional geochemical study was performed on 38 test gases collected from 9 Neogene western Nile delta discoveries to determine whether microbial or thermogenic processes are the dominant generation pathways of methane.

Modelling isotope fractionation during primary cracking of natural gas: a reaction kinetic approach
TL;DR: A numerical model has been developed to compute stable carbon isotope variations in natural gas (methane) by calculating 13 CH 4 and 12 CH 4 generation as a set of parallel first-order reactions of primary cracking as mentioned in this paper.

Methane generation from coal during open system pyrolysis investigated by isotope specific, Gaussian distributed reaction kinetics
TL;DR: In this article, a reaction kinetic model is presented to differentiate individual complexes of reactions of the thermal decomposition of sedimentary organic matter during pyrolysis experiments, which is applied to methane generation from coal during open system pyrolys experiments with linear heating.
