CATALYST FOR MANUFACTURING CARBON

摘要

PROBLEM TO BE SOLVED: To improve the carbon producing capability of a catalyst for manufacturing carbon. SOLUTION: When a 1% potassium-load cobalt catalyst A obtained by load potassium to cobalt is used, the optimal catalytic temperature can be lowered from 510-520 deg.C to 410-430 deg.C compared to the case in which a cobalt catalyst (a) is used. In addition, the maximum conversion rate can be increased from 6.8% to 18.0% and further, the average conversion rate and the carbon deposition level can be upgraded.
