Biodiesel is an alternative fuel produced from vegetable oils or fats through transesteriflcation reaction with methanol and sodium hydroxide as catalyst. The acidity of these raw materials is given by free fatty acids that are transformed into soaps in the presence of a base and water. Since the formation of soap cause problems in the steps of washing and purification of biodiesel and decrease of yield, vegetable oils or fats with high acidity could not be used for the conventional process of alkaline catalysts. If free fatty acids are present, they can be removed or transformed into biodiesel using special pretreatment technologies. In this research two methods of deacidification such as neutralization and extraction were being explored for the reduction of acidity of some vegetable oils such as rice bran, palm and palm kernel oils having different acidities. The oils were first pretreated by filtration, degumming and winterization. The pretreated oils were then deacidified by either neutralization or extraction. It was found that neutralization gave more reduction in acidity but percent yield was low. Stepwise extraction made more yield of oils having low acidity less than 2.0."}]},"item_1583103108160":{"attribute_name":"Keywords","attribute_value_mlt":[{"interim":"biodiesel"},{"interim":"transesterification"},{"interim":"free fatty acids"},{"interim":"deacidification"},{"interim":"neutralization"},{"interim":"extraction"}]},"item_1583103120197":{"attribute_name":"Files","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2021-01-07"}],"displaytype":"preview","filename":"44.pdf","filesize":[{"value":"1.8 MB"}],"format":"application/pdf","licensetype":"license_0","url":{"url":"https://meral.edu.mm/record/7273/files/44.pdf"},"version_id":"9368449f-2fe7-498d-9c07-227414c3ae6d"}]},"item_1583103131163":{"attribute_name":"Journal articles","attribute_value_mlt":[{"subitem_journal_title":"WYU Research Journa","subitem_pages":"176-188","subitem_volume":"Vol.4"}]},"item_1583105942107":{"attribute_name":"Authors","attribute_value_mlt":[{"subitem_authors":[{"subitem_authors_fullname":"Khin Htwe Nyunt"},{"subitem_authors_fullname":"Khin Sein"},{"subitem_authors_fullname":"Bo BoThet"}]}]},"item_1583108359239":{"attribute_name":"Upload type","attribute_value_mlt":[{"interim":"Publication"}]},"item_1583108428133":{"attribute_name":"Publication type","attribute_value_mlt":[{"interim":"Journal article"}]},"item_1583159729339":{"attribute_name":"Publication date","attribute_value":"2014-11-01"},"item_title":"Studies on Processes for the Reduction in Acidity of Some Vegetable Oils","item_type_id":"21","owner":"16","path":["1582967436313"],"publish_date":"2021-01-07","publish_status":"0","recid":"7273","relation_version_is_last":true,"title":["Studies on Processes for the Reduction in Acidity of Some Vegetable Oils"],"weko_creator_id":"16","weko_shared_id":-1},"updated":"2021-12-13T02:57:26.879770+00:00"}
