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.
Claims9
A method of producing carbon by bringing a catalyst mainly composed of at least either nickel or cobalt with an alkaline metallic element added thereto into contact with mixed gas containing a carbon source.
A method of producing carbon comprising the steps of:
- preparing a catalyst comprising one of nickel and cobalt with an alkaline metallic element, a weight ratio of alkaline metal to a total weight of said catalyst is approximately 1%;
- and
- contacting said catalyst with a mixed gas, said mixed gas containg a carbon source.
