The acorn (Quercus frainetto L.) kernel oil is extracted from the kernels of the acorn that is grown in Sakarya which is in the Marmara region, Turkey. Acorn kernel oil (AKO) is obtained in 10 wt. %, by solvent extraction. Acorn kernel oil is investigated as an alternative feedstock for the production of a biodiesel fuel. The fatty acid profile of the oil consists primarily of oleic, linoleic, palmitic, and stearic acids. Before processing alkalin transesterification reaction, the high free fatty acid (FFA) of the crude acorn kernel oil is decreased by using acid esterification method. Biodiesel is prepared from acorn kernel (AK) by transesterification of the acid esterified oil with methanol in the presence of potassium hydroxide (KOH) as catalyst. The maximum oil to ester conversion was 90%. The viscosity of biodiesel is closer to that of diesel and the heating value is about 6.4% less than that of petroleum diesel No. 2. All of the measured properties of the produced acorn kernel oil methyl ester (AKOME) are being compared to the current quality requirements according to EN14214 and ASTM D 6751. The comparison shows that the methyl esters of acorn kernel oil could be possible used as diesel fuel replacements.

Allanblackia Parviflora

AbstractThis study is aimed at producing biodiesel from Allanblackia parviflora seed oil as a new non-edible alternative resource. The amount of oil extracted from the seeds was approximately 49% and was mainly composed of linoleic acids (66.68). The Allanblackia parviflora methyl esters (APME) were prepared using NaOH as a homogeneous base-catalyst for the transesterification. The rate of conversion of the triglycerides to methyl esters was determined using Gas Chromatograph with an optimum yield of 97.1%. The conditions under which this maximum yield (97.1%) was obtained include methanol to Allanblackia parviflora oil ratio of 6:1, reaction temperature of 60 ℃, NaOH concentration of 1% and reaction time of 2 h. The properties of the methyl esters were comparable to fuel properties of conventional diesel using ASTM and European Union standards. The seeds of Allanblackia parviflora can be described as promising non-edible resource.

Microalgae appeared to be an alternative feedstock for renewable biodiesel production due to their capability to accumulate considerable amounts of lipids. In this study, mutagenesis using UVC light with different periods was applied to Chlorella sp. 042 to produce a microalgae strain with high lipid productivity of 45, 60, and 75 min. The Nile red fluorescence method was conducted to select a Chlorella sp. mutant with high neutral lipid and generated one mutant from every UV mutation period, M45-06, M60-02, and M75-21. All of the mutants have higher growth rates than the wild type. Chlorella sp. 042 M60-02 achieved the highest lipid productivity, with 34 mg L-1 day-1. Furthermore, as other major biochemical components, carbohydrate and protein contents were determined. Our results showed that all the mutants enhance their carbohydrate and protein contents compared to the wild type. However, mutations for more than 60 min do not intensely change the protein content of mutant microalgae. Gas chromatography-mass spectrophotometry analysis revealed that M60-02 mutant has similar FAME profiles with the wild type, which contain palmitic acid (C16:0), stearic acid (C 18:0), oleic acid (C18:1), and linoleic acid (C18:2). These results demonstrate that the UV mutation of Chlorella sp. 042 for 60 min is suitable as a source of biodiesel production.

The use of biodiesel and the requirement of improving its production in a more efficient and sustainable way are becoming more and more important. In this research work, castor oil was demonstrated to be an alternative feedstock for obtaining biodiesel. The production of biodiesel was optimized by the use of a two-step process. In this process, methanol and KOH (as a catalyst) were added in each step, and the glycerol produced during the first stage was removed before the second reaction. The reaction conditions were optimized, considering catalyst concentration and methanol/oil molar ratio for both steps. A mathematical model was obtained to predict the final ester content of the biodiesel. Optimal conditions (0.08 mol·L−1 and 0.01 mol·L−1 as catalyst concentration, 5.25:1 and 3:1 as methanol/oil molar ratio for first and second step, respectively) were established, taking into account the biodiesel quality and an economic analysis. This type of process allowed cost saving, since the amounts of methanol and catalyst were significantly reduced. An estimation of the final manufacturing cost of biodiesel production was carried out.

Alternative Feedstock

Biodiesel is one of the promising renewable sources to fulfill the future energy demand of the world. Sustainable feedstock for biodiesel production is one of the major criteria to ensure the process of renewability. Chicken fat is an encouraging feedstock for biodiesel. In this study, waste chicken fat was converted to biodiesel via catalysed transesterification. Optimised process parameters were recorded at 1:4 oil-to-methanol volume ratio and 0.5 wt% KOH catalyst concentration with a biodiesel yield of 96%. The FT-IR spectral analysis of chicken fat and chicken fat biodiesel confirmed the conversion of chicken fats into biodiesel. The physico-chemical properties of biodiesel were tested in accordance with ASTM D6751 and EN 14214 biodiesel standards. The specific fuel properties of chicken fat biodiesel that include calorific value, viscosity and acid value were found to be lower than that of petrodiesel. The diesel engine performance tests confirmed that the biodiesel blends performance was similar to petrodiesel.  It is noted that while the brake horsepower increased with the increase of biodiesel blending percentage, the engine power output was found to decrease. Specific fuel consumption also increased along with the biodiesel blending percentage.
