    Abstract
  • The effects of element sulfur on carbon isotopic fractionation of methane have been systematically studied by the simulation experiments of thermal transformated methane from organic matter.The results show that during the low to middle temperature,the values of methane carbon isotope from similitude kerogen and total rock are lighter in the presence of element sulfur than in the absence of element sulfur.The changing extent of carbon isotope is different at different tempertures and the organic type by effects of element sulfur.Carbon isotopic value of methane from similitude kerogen is lighter than that from total rock in the presence of element sulfur.Carbon isotopic values of methane from total rock series are lightening with the increasing maturity of organic matter in the presence of element sulfur.Mechanics analysis revealed that element sulfur is mostly effect carbon isotopic values of methane as a reactant.
