| http://www.w3.org/ns/prov#value | - It was found that the efficient metal catalyst particles contain such metals as Ni, Fe, Co, Cu, Mo or their combination, and the optimum temperature range for the growth of TCF is within 500-1200??? C. The addition of hydrogen gas to CG (at the ratio from 0.1:1 to 1:1 by volume) in many cases increases the yield of TCF. It appears that the growth of secondary and tertiary carbon filaments on the s
