Sustainable biodiesel production from cottonseed oil using a nickel-doped eggshell heterogeneous catalyst optimized via response surface methodology
{{output}}
This study presents a sustainable and low-cost approach to biodiesel production using non-edible cottonseed oil and a novel nickel-doped chicken eggshell-derived catalyst. The catalyst was synthesized via nickel impregnation followed by calcination at 900 °C ... ...
