For the fluorination of $CF_2Cl_2$, the yield of $CF_4$ was found to be increased with the contact time and the reaction temperature. When the mole ratio of HF/$CF_2Cl_2$ is 3 or above, the yield of $CF_4$ was attained to 100% at $370^{\circ}C$ and contact time of 3 seconds. In the case of the fluorination of $CCl_4$ with HF, the yield of $CF_4$ was obtained above 90% at the reaction temperature of $500^{\circ}C$, the contact time of 3 seconds, and the mole ratio of HF/$CCl_4$ of 5.
