Kitchen waste based adsorbents for deacidification of crude oil

The high acidity in crude oil, often expressed as Total Acid Number (TAN), is corrosive; posing significant operational and economic challenges in refining crude oil. With the aim of deacidifying crude oil via TAN removal, biogenic, sustainable activated carbons (KAC) were designed via an initial carbonization of kitchen waste to biochar followed by its impregnation with KOH with subsequent activation under inert atmosphere. The carbonaceous and porous nature of the KACs were reflected from FE-S
