文摘
- •
3% nitric oxide decelerates the Co–Al LDH decomposition, but causes better crystallized Co–Al oxide.
- •
Presence of nitric oxide in calcination medium causes also better crystallized metallic cobalt after reduction.
- •
The observed difference in the Co0 size does not affect the activity in FTS.
- •
The catalysts precalcined in inert gas with 3% of NO produce less methane and more olefins.
