The reaction time varied in the range of 2-6 hs. The optimum condition has been obtained by flow rate, density, and acid number analysis of biodiesel product. The results show that biodiesel product from palm oil has optimum reaction time of 4-5 h with percentage of conversion of 33.33%. The same optimum reaction time is also shown for biodiesel product from waste cooking oil, however, the percentage of conversion is higher, ie. 57.14%. The higher reaction time (6h) yields lower percentage of conversion due to back reaction of hydrolysis of fatty acid ester. publisher: IJISRT date: 2019-07 type: Article type: PeerReviewed format: text language: en identifier: https://repository.unp.ac.id/id/eprint/38651/1/3_TURNITIN%20Biodiesel%20Production%20from%20Palm%20and%20Waste%20Cooking%20Oils%20Catalyzed%20by%20Silica_Titania%20Catalyst%20with%20Time%20Variation.pdf identifier: Farianty, Dhika and Putra, Ananda and Latisma DJ, Latisma DJ and Nizar, Umar Kalmar and Sundari, Rita (2019) Biodiesel Production from Palm and Waste Cooking Oils Catalyzed by Silica-Titania Catalyst with Time Variation.
