Castor oil biodiesel production and optimization
Castor oil contains 80–90% of hydroxyl fatty acid, ricinoleic acid and about10% non-hydroxylated fatty acids, mainly oleic and linoleic acids.Such especial composition causes a disadvantage for its use for biodiesel production, since its viscosity is about 7 times higher than the one of other vegetable oils .To avoid this disadvantage, castor oil biodiesel when blends with petrodiesel it has

Castor oil biodiesel production and optimization
Biodiesel is evolving to be one of the most employed biofuels for partial replacement of petroleum based diesel fuel, especially in recent years. The most widely used feedstocks for biodiesel production are vegetable oils. In this work, biodiesel production from castor oil has been synthesized by homogenous alkaline transesterification.
Abstract and Figures. The transesterification of castor oil with ethanol in the presence of sodium ethoxide as catalyst is an exceptional option for the Brazilian biodiesel production, because the
Biodiesel Production from Castor Oil: Optimization
Accordingly, the optimum conditions for biodiesel production from mixed oil were a catalyst concentration of 1.23 % w.t of the oil, alcohol to mixed oil molar ratio of 5.94 :1 (v/v) and reaction
transesterification for biodiesel production. From the titration method, the acid value. of FF A in crude castor oil was determined. to be between 20% to 23%, which is higher. than 4%. The best
Optimization of biodiesel production from castor oil using
Abstract. In this study, optimization of biodiesel production from castor oil using full factorial design was investigated. The biodiesel production was carried out in a batch laboratory scale reactor by alkaline-catalyzed transesterification process. Experimental design was used in the evaluation of process variables.
Table 4 presents the castor oil biodiesel properties. The ethyl ester from castor oil presents higher viscosity than the biodiesel specification, according to the Brazilian National Agency of Petroleum (ANP), the biodiesel viscosity is from 3.0 to 6.0 mm 2 /s. The castor oil biodiesel viscosity is about four times higher than the ANP norms.
Production of Biodiesel from Castor Oil: A Review
Ni-doped ZnO nanocatalyst for biodiesel production using castor oil as a feedstock. The results obtained show a 95.20% yield under optimal conditions (1:8 oil:methanol, 11% of catalyst, 60 min,
oils need to be conducted. One such oil would be castor seed oil, which has merely less than 0.15% in the international oil seed trade market for the biodiesel production. Castor (Ricinus communis) plant is a specie that belongs to the Euphorbiaceae family and is commonly known as castor oil
