Methyl Ester Production from Schlichera Oleosa
نویسندگان
چکیده
Biodiesel is produced from vegetable oils (edible & non edibles) and animal fats. The methyl ester of vegetable oils, known as biodiesel are becoming increasingly popular because of their low environmental impact and potential as a green alternative fuel for diesel engine and they would not require significant modification of existing engine hardware. At present, biodiesel is commercially produced from the refined edible vegetable oils such as Schlichera oleosa seeds oil, etc. by alkaline-catalyzed esterification process. This process is not suitable for production of biodiesel from many unrefined non-edible vegetable oils because of their high free acid value. Hence, a two-step esterification method is developed to produce biodiesel from high FFA vegetable oils. The biodiesel production method consists of acid-catalyzed (H2SO4) pretreatment followed by an alkaline-catalyzed (KOH) transesterification. Methyl ester of Schlichera oliosa is derived through esterification and transesterification process.

متن کاملOptimization of Biodiesel Production by Chemical Trans-esterification of Sunflower Oil
Vegetable oils and fats in comparison with diesel fuel have high viscosity, by transesterification method the viscosity of oil can be decreased. Transesterification of triglyceride with alcohol is one of the methods for production of biodiesel. In this study sunflower oil, methanol and ethanol, with molar ratio of (1:3, 1:4, 1:6, 1:8) and temperature (40, 50, 60 º C) were dependent parameters e...

Since the conventional esterification method requires longer processing time and obtain low yield, the intensification of this process is still interesting subject to be investigated. To reduce the oil extraction cost from seeds which almost 70% of total processing cost, in situ esterification has been recently introduced. The objective of study was to produce biodiesel from rubber seeds oil th...
متن کاملEffect of Neutrophils on Nitric Oxide Production from Stimulated Macrophages
Background: During the initial phase of an infection, there is an upregulation of inducible nitric oxide synthase in the macrophages for the production of nitric oxide. This is followed by the recruitment of polymorphonuclear leukocytes (neutrophils) which release arginase. Arginase competes with inducible nitric oxide synthase for a common substrate L-arginine. Objective: To investigate whethe...
