“…This method has been used by many researchers to explore, find, and optimize the operating conditions (temperature, alcohol to oil molar ratio, catalyst amount, and time) of the biodiesel reaction. Taguchi technique is a fast and economic way of understanding interactions between different parameters, predicting maximized yields by conducting limited experiments and minimal resource consumption in comparison with conventional method of one factor at a time, which is a time‐consuming and labor‐exhausted one . In this study, biodiesel production was evaluated at different intervals of process parameters by using Taguchi technique for experimental design.…”

Summary In this study, a strong acidic‐type cation exchange resin was used in the transesterification of corn oil to fatty acid methyl esters (FAME). The gel‐type cation exchange resin (Purolite‐PD206) was used in H+ and Na+ forms to utilize ion‐exchange resin as effective heterogeneous catalyst in the production of biodiesel. Effect of ionic forms of ion exchange resin on free fatty acid (FFA) conversion and composition was investigated by using different amounts of ion exchange resin (12, 16, and 20 wt%), various mole ratios of methanol to oil (1:6, 1:12, and 1:18 mol/mol), reaction temperatures (63, 65, and 67°C), and reaction time (24, 36, and 48 h) during transesterification reaction. The highest FFA conversions of 73.5% and 79.45% were obtained at conditions of 20 wt% of catalyst, 65°C of reaction temperature, 18:1 as methanol to oil ratio, and 48 h of reaction time for H+ and Na+ forms of ion exchange resin, respectively. These results were obtained from regression equations established by using analysis of variance (ANOVA) model according to the experimental results of selected parameters. Gas chromatography analysis revealed that FAME is mainly composed of C16:0 (palmitic), C18:1 (oleic), and C18:2 (linoleic) acids of methyl ester.

“…The model and the model parameters can be decided to have higher signicance on the basis of higher SS and F-values and a lower p-value. 19 It is evident from Table 3 that the developed model possesses a large SS value (3613.77) and F-value (147.12), and the p-value of 0.000815 points out the fact that there is only a 0.08% chance of obtaining the large F-value due to noise. Therefore, it may be concluded that the developed model is signicant and can be used for the prediction of adsorption performance.…”

“…Since the fatty acid content dictates the specific gravity, a denser vegetable oil processes into a denser biodiesel Low ash content and carbon residue contents produced lower deposition of carbon on engine parts and increases the engine life [25]. The ash content of synthesized biodiesels were found to be considerably low, but higher than those of fossil diesels.…”

Increasing demands coupled with environmental effects of conventional fuels have over time been a source of great concern to seek cost-efficient and environmentally friendly fuels. This work is therefore, to determine the fuel properties of biodiesel from neem (Azadirachta indica) and jatropha (Jatropha curcas) seed oils using whole-cell biocatalyst. Seeds of both neem and jatropha wyere extracted from kernels using a two-staged mechanical process. Whole-cell biocatalyst-mediated trans-esterification of oils into fatty acids methyl esters (FAME) were achieved by the used of isolated strains of Rhizopus orizae. After pretreatment, the percentage yield of oils from seed kernels of neem and jatropha were found to be 29.49±0.12% and 34.18±0.16% respectively while biodiesel yields from oils of neem and jatropha were 91.20±0.02% and 89.90±0.08%. The neem and jatropha based biodiesels had specific gravities of 0.879±0.002 and 0.877±0.001, flash points (173±1.11 and 135±1.14oC); fire points (205±0.11 and (193±0.01oC) water and sediments (0.04±0.001 and 0.02±0.001%); kinematic viscosity (2.30±03 and 2.10±0.06 cst @ 37.8oC); API gravity (29.48±0.37) and (29.85±1.9); free fatty acids (0.65±0.03 and 0.38±0.04% KOH); ash contents (0.03±0.001 and 0.01±0.001%); iodine number (79.6±0.1 and 20 ±0.2 mg I2/g); saponification value (186.38 ± 0.17) and (191.75 ± 0.11mg (KOH)/g); and peroxide value (7.91±0.09 and 2.50 ± 0.03mg/kg), respectively. Fuel properties of biodiesel compared favorably with American standards for testing materials (ASTM) established limits for biodiesel fuels which showed great potentials in the use of non-food oils coupled with green chemistry in the field of biodiesel research and development.
