Abstract
SiO2np derived from rice husk were chemically connected to the surface of modified Calcium Oxide (CaO) in a straightforward manner to produce fatty acid methyl ester (FAME) from waste cooking oil (WCO) with great efficiency. After 3 h at a reaction temperature of 80° C, it was discovered that WCO could produce 97.8% yield of the FAME of the modified CaO, which is much greater than the yield of 83.5% over unmodified CaO under the same reaction circumstances. The results showed that following modification, well-dispersed CaO with relatively tiny particle sizes and large surface areas was produced. Additionally, the changed CaO with very little Ca(OH)2 is produced during the modification process. The use of leftover modified CaO-nanoparticles as a heterogeneous transesterification catalyst has been identified after fourteen cycles.
