Fische-|Tropsch synthesis experiments indicate that carbon isotopes of alkane gases reversed in these experiments on occasion. By analyzing the whole process and data of all researchers,the probable interpretations are deduced as fellows. As the products conversion heightening with the experiment time and temperature increasing,the control of alkane carbon isotope fractionation in the experiments was gradually shifted from kinetic mechanism to thermodynamic equilibrium. Series of carbon isotopes of alkane gases were changed from reversed to normally distribution just like alkanes in natural gas. The experiments were controlled by kinetic fractionation on the conditions of short time reaction (low conversion) or in an opened system (discharging following the reaction). And the electric spark synthesis experiment was more an ideal condition delegating the course of carbon isotope fractionation.
