D-7 VEGETABLE OILS AS A FUEL FOR DIESEL TRANSPORT ENGINES : A PRELIMINARY STUDY OF OXIDATIVE STABILITY(Session: Forming/Vegetable-oil/Rubber)
詳細
High petroleum price had a great impact on the nonoil producing countries like Thailand. In this work, an attempt was made to analyse the resistance to an oxidation process of various crude vegetable oils produced in Thailand with RANCIMAT instrument. The fatty acid compositions and the amount of natural antioxidants were directly related to the result of oxidation stability. An addition of commercial antioxidants increases both crude oil and its fatty acid methyl esters (FAME) or biodiesel oxidation stability. Crude palm oil (CPO) met the European oxidation stability standard (EN14112) which has set a minimum RANCIMAT Induction time of 6 h.
