With recent concern over potential global climate changes, interest has resurfaced into renewable fuels. Efficiency in C02 utilization, lower pollutant emissions, national security and diversity of energy sources are just a few advantages of renewables. Microalgae, small single cell plants, can be cultured on arid lands to produce storage lipids. These storage lipids can be chemically transformed into a liquid fuel that has many of the characteristics of a #2 diesel fuel. Micro algae from the Solar Energy Research Institute were mass cultured and harvested. Several solvents systems were evaluated for their ability to extract microalgal lipids. Several solvents were identified as being promising and these were scaled up to evaluate handling and efficiency of extraction. Lipid produced from the extraction process were transesterified into fatty acid methyl esters (FAMES). Statistical designed experiments were developed to identify and optimize the important variables in the reaction.

Renewable vegetable fuels are spreading rapidly throughout Europe and North America. Because biodiesel fuel has now acquired an important market share, it is necessary to thoroughly examine aspects of its use not previously considered either at the research stage or when overhauling the production technology. One of these aspects is its medium-term storage. The object of the present work is to study the behavior of biodiesel under controlled storage conditions that simulate those found in reality. Samples of biodiesel were kept in the dark, at two different temperatures (20°C and 40°C), in both glass and iron containers. They were controlled by the parameters that indicate their state of oxidation. Another group of samples was stored in glass and kept under the conditions described above in the presence of increasing quantities of water to determine its influence on the formation of acidity.JAOCS 72, 699-702 (1995).

“…The reduction of vegetable oil viscosity has been studied by both physical and chemical methods (7), including dilution (8,9), microemulsification (10,11 ), cracking; and hydrocracking (12)(13)(14). Transesterification, producing fatty acids methyl esters (FAME) by alkali-catalyzed reaction, is the most applied process (4,(15)(16)(17).…”

One of the main problems in the study or industrial application of transesterification processes for vegetable oils is how to measure the methyl ester content. In this work, a quick analytical method was developed for assessing the methyl ester content of purified "fuel grade" transesterification products by applying a simple correlation with viscosity. The correlation was tested on a wide range of samples with various methyl ester contents; the results were in agreement with the values measured by gas-chromatographic analysis. In a defined range of weight fractions the correlation allows for the determination of the methyl ester content of purified transesterification products by a single viscosity measurement. This method is especially suitable for process control purposes as it determines the methyl ester content quickly and simply.JAOCS 72, 1399-1404 (1995).KEY WORDS: Density measurement, diesel oil substitute, esterification, methyl ester density, methyl ester determination, EXPERIMENTAL PROCEDURESIn order to have samples with various degrees of purity, a number of transesterification reactions were caaa'ied out in the laboratory. The soybean oils used for transesteri;fication reactions were refined, edible-grade oils. Methanol, HPLC-grade (Aldrich, Steinheim, Germany), was used without further purification. These oils exhibited an average saponification number of 192, iodine number of 133, and an acid number of 0.06. Karl Fischer titration before use gave values <0.15% water. Reagent-grade sodium hydroxide was used as a catalyst.In order to determine the FAME and glyceride content of the transesterification products, sample preparation and GLC
