Nanocatalysts play a significant role to improve the thermal and physical properties of biodiesel. In present work, multiwalled carbon nanotubes (MWCNTs) as an additive with fraction 30, 40, 50 ppm are dispersed different biodiesel–diesel blends 10%, 30%, 50% waste cooking oil (WCO)-based biodiesel (B10, B30, B50) for prediction four-stroke compression ignition (CI) engine emissions using multi...

Eggshell has a shaft and high surface area, so it the potential to become an adsorbent. The adsorbent is in filtration process. Waste cooking oil can be reused as raw material with economic value. So far, waste bank that accommodates used not gone through process, selling price low. filtered using various media, including activated carbon, commercial silica, local adsorbents such eggshells. A p...
