The present study was based on the production of bioethanol from alkali-pretreated seed pods Bombax ceiba. Pretreatment is necessary to properly utilize for via fermentation. This process assures accessibility cellulase cellulose found in seedpods by removing lignin. Untreated, KOH-pretreated, and KOH-steam-pretreated substrates were characterized morphological, thermal, chemical changes scanni...

The embedded immobilized enzymes (Rhizopus-oryzae) on the magnetic nanoparticles (Fe3O4-NPs) is a new application for sustainable production of high-quality biodiesel. In this study, biodiesel derived from Kapok oil via ultrasonication (US)-assisted catalytic transesterification method. A novel attempt made to prepare by an enzyme solve problem denaturation. This innovative method resulted in o...

This research focuses on producing biodiesel through the transesterification process of Ceiba pentandra triglyceride acid using a CaO/Hydrotalcite (CaO/HTC) catalyst. study aimed to determine effect adding catalyst mass, mole ratio oil: methanol yield, and knowing FAME content yield highest impact mass kapok seed oil FFA conversion results. Kapok was transesterified for 2 hours at temperature 6...
