Abstract: A method of nitrogen fixation uses a synthesis gas formed of several gaseous reactants for the synthesis of a synthesis product; and a process gas formed by admixing a gaseous catalyst with the synthesis gas, with the molar proportion of the catalyst in the process gas no more than 33%. The mixing ratio for the several gaseous reactants in molar proportions is determined by: determining all atom types in the synthesis product; calculating the reciprocal of the total effective cross section (RTECS) for the ionization and excitation of atoms by electron impacts on the respective atom type; multiplying the RTECS values by the number of atoms of the respective atom type in the synthesis product; determining the mixing ratio of the reactants, in that the number of atoms of the atom types in the reactants corresponds approximately to the ratio of the multiplied RTECS values for the corresponding atom types.
