Abstract

Ljuske palminih jezgri (PKS) postupno su isprane vodom i ledenom octenom kiselinom (CH3COOH) kako bi se pripremile za suspaljivanje s ugljenom. Zatim su toreficirane na 450 ºC jedan sat. Pranje je obavljeno kako bi se smanjila koncentracija pepela i alkalnih oksida, što bi smanjilo mogućnost stvaranja troske i obraslina. Istraživanje je provedeno s obzirom na to da su informacije o ispiranju PKS-a octenom kiselinom i njihovu toreficiranju vrlo ograničene i nejasne. Rezultati su pokazali da isprani i toreficirani PKS ima bolja svojstva od sirovoga PKS-a ili onoga ispranog vodom. Mješavina ugljena s PKS-om ispranim kiselinom i toreficiranim ima nisku šljaku i srednju tendenciju obraštanja. Međutim, na temelju temperature taljenja pepela, sklonost stvaranju šljake i obraslina visoka je u redukcijskim uvjetima i srednja u uvjetima oksidacije.
