Abstract
By employing a 1% potassium-added cobalt catalyst prepared by adding potassium to cobalt as a catalyst for depositing carbon from mixed gas containing a carbon source, it was possible to lower the optimum catalyst temperature from 510-520° C. to 410-430° C., increase the maximum conversion ratio from 6.8% to 18.0% and increase both of the mean conversion ratio and the carbon deposition quantity as compared with the case of employing a catalyst of simple cobalt.
