การผลิตน้ำมันไบโอดีเซลที่มีการแยกกลีเซอรีนออกอย่างต่อเนื่อง / ธนยศ จาติกวณิชย์ = Production of biodiesel with continuous removal of glycerin / Thanayoth Jatigavanich
This research is the study of production of methyl esters using a reaction system which is capable of continuous removal of glycerin. Palm olein oil and methanol are tranesterified at oil to methanol molar ratio of 1:6 catalyzed by 1 wt% of basic type catalyst. The experiments are conducted at 60 degree Celsius and at atmospheric pressure. The results show that the reaction system which is capable of continuous removal of glycerin gives lower conversion than the reaction system without removal of glycerin. Analysis of reaction products shows that large quantity of methanol and catalyst dissolve in glycerin resulting in the loss of both components from reaction systems which are the main causes of lower in rate of reaction and conversion. Addintion of catalyst and methanol to the reactor system at the same amount brings the conversion back to the same conversion.
