Abstract

In this work, physicochemical properties of the waste used oil (WUO) were carried out for its aptness for biodiesel production. Burnt Animal Bone was used as a precursor for the biodiesel production. The produced biodiesel was characterized and the optimum biodiesel produced was determined via statistical analysis. This was with a view to add value to WUO and finding environmentally friendly alternative to fossil fuel. WUO was obtained from eatery in Yenegoa, Bayelsa State, Nigeria. The foreign materials and dirt in the oil was removed by filtration after preheating. The physiochemical and other parameters (cetane number, API, aniline point among others) properties of WUO were determined using standard methods. The BAB was burnt to ash in a furnace, sieved into fine powder, and then characterized using FTIR, SEM, XRF, BET adsorption, and qualitative analysis. Biodiesel production was done via base catalyst transesterification while statistical analysis was done using Microsoft Excel 8.0. In order to ascertain the quality of the biodiesel, the physicochemical properties were determined. Results showed that the refined WUO properties were in line with oil property requirement for biodiesel production. The physicochemical characteristics of the WUO showed physical state of the oil to be liquid/dark brownish at 28 oC, viscosity 6.58 cP at 28 oC, acid value, 0.96 (mg KOH/g oil), FFA (% oleic acid), 0.48, iodine value, 152.00 (g I2/100g oil), peroxide value, 5.1 milli-equivalent of peroxide/kg of oil among others. The derived catalyst showed high basic strength with Calcium oxide (87.63 wt. %) as the dominant element in the catalyst. Optimum biodiesel yield was obtained at run 5 with 98.52 (%wt. /wt.) at reaction time of 30 min, catalyst amount of 2.0 (%wt.), reaction temperature of 100 oC, and ethanol-oil molar ratio of 4:1. The produced biodiesel properties conformed to the recommended standard ASTM D6751 and EN 14214. The study concluded that WUO could serve as feedstock for biodiesel production that is environmentally friendly and the derived catalyst could be used as a bio-base in Industries.
