This research work concerns with the transesterification of castor oil with methanol to form biodiesel. As the free fatty acid content in castor oil is more than 1%, an acid catalyst namely, H 2 SO 4 has been used for esterification. The experimental conditions were determined using central composite design method and the experiments were conducted in a 2 L working volume fully controlled reactor. The input conditions namely, catalyst concentration, methanol to oil molar ratio and temperature were varied, and % fatty acid methyl ester (FAME) content was determined. Based upon the experimental data, an ANN model has been developed which is used to predict %FAME yield for a given set of input conditions. The experimental data and the data predicted by the ANN model have been used to estimate the rate constants of a kinetic model. The ANN model predicts the % FAME yield within ±8% deviation, and the developed kinetic model shows successfully the effect of methanol to oil molar ratio on % FAME yield at 60°C and 3% (v/v) catalyst loading.

“…Castor bean (Ricinus communis L.) is considered to be one of the most promising non-edible oil crops due to its high potential for annual seed production and its tolerance to diverse environmental conditions. In addition, castor bean can be grown on marginal lands which are usually unsuitable for food crops [3][4][5].…”

Abstract:The effects of plant species (castor bean (Ricinus communis L.) versus sunflower (Helianthus annus L.)) and irrigation regime (freshwater versus secondary treated municipal wastewater) on soil properties and on seed and biodiesel yield were studied in a three year pot trial. Plant species were irrigated at rates according to their water requirements with either freshwater or wastewater effluent. Pots irrigated with freshwater received commercial fertilizer, containing N, P, and K, applied at the beginning of each irrigation period. The results obtained in this study showed that irrigation with effluent did not result in significant changes in soil pH, soil organic matter (SOM), total kjeldahl nitrogen (TKN), and dehydrogenase activity, whereas soil available P was found to increase in the upper soil layer. Soil salinity varied slightly throughout the experiment in effluent irrigated pots but no change was detected at the end of the experiment compared to the initial value, suggesting sufficient salt leaching. Pots irrigated with effluent had higher soil salinity, P, and dehydrogenase activity but lower SOM and TKN than freshwater irrigated pots. Sunflower showed greater SOM and TKN values than castor bean suggesting differences between plant species in the microorganisms carrying out C and N mineralization in the soil. Plant species irrigated with freshwater achieved higher seed yield compared to those irrigated with effluent probably reflecting the lower level of soil OPEN ACCESSWater 2011, 3 1113 salinity in freshwater irrigated pots. Castor bean achieved greater seed yield than sunflower. Biodiesel production followed the pattern of seed yield. The findings of this study suggest that wastewater effluent can constitute an important source of irrigation water and nutrients for bioenergy crop cultivations with minor adverse impacts on soil properties and seed yield. Plant species play an important role with regard to the changes in soil properties and to the related factors of seed and biodiesel yields.

Material compatibility with biodiesels and their blends should be verified on a case-by-case basis to ensure long term durability of storage tanks and pipelines. This paper aimed to investigate the degradation of physical properties such as mass, volume, tensile strength, hardness and change in surface morphology for polymers namely polypthalamide (PPA) and polyarylamide (PAA) upon exposure to Pongamia pinnata biodiesel (PPB) and blends. Static immersion tests in B0, B10, B20 and B100 were carried out at 25, 50 and 75 °C for 120, 360 and 720 h to estimate the degradation behaviour of polymers under static condition. Rotating cage was used to study the degradation behaviour at room temperature for 120 h under flow conditions. Significant changes in the physical properties and surface morphology was observed. The overall compatibility sequence of polymers in Pongamia pinnata biodiesel under static condition was found to be PAA > PPA while under flow condition, the order is and PPA > PAA under flow condition.
