Identification of Non-edible Seeds as Potential Feedstock for the Production and Application of Bio-diesel

Abstract: Increasing demand of conventional source of fuel has made people to consider on alternative fuels that can substitute the present demand by some percentage. This paper presents the state of the art in this area by reviewing number of contributions fro m the all three disciplines i.e. Botany, Chemistry and Engineering are taken together to critically rev iew the work done in this field of Bioenergy. Large nu mber of survey and work is done in identification of non-edible seeds as potential feed stock fro m wh ich oil can be extracted. Experimental investigation has been done by several researchers in production of Bio-d iesel fro m oil extracted, trans-esterified and studied different propert ies of fuel produced. This fuel and it's different b lends with diesel are used by engineers to understand the performance of engine. Nu mber of experimental work is done using fuel available fro m non-edible o ils feedstock to investigate performance of this biodiesel using compression ignition engine. In this review, the findings reported by different researchers have been summarized to portrait the use of non-edible seeds for the production, mathematical model and application of bio -diesel. For the industrial and economic gro wth, there should be enough supply of electricity and transport facility in the country. The fossil fuels used are non-renewable and due to continue use, they will deplete in the future and there will be energy crisis in the world. The use of fossil fuels also p ol lut es t he environm ent and causes environm ental prob lems like g lobal warmin g, g reenhouse effect, air pollution etc. Moreover, important fossil fuels like o il and gas are concentrate in some of the countries, resulting the remain ing countries like India have to co mpletely depends on such countries which are p roducing oil and gas. Due to Globalization, developing countries like India and Ch ina, the consumption of petro leu m products and natural gas increases year by year at unbelievable rate. In India o il prov id es energy fo r 95% of t ranspo rtat ion fo r wh ich domestic supply of crude will satisfy only about 22% of the demand and the rest will have to be met fro m imported crude(1). As a result, the import bill also increases. This adversely affects the economy of country.

Investigating production parameters and impacts of potential emissions from soybean biodiesel stored under different conditions

Abstract: Biodiesel production parameters and the impact analysis of the potential emissions from both soybean biodiesel and washing water stored in three different environmental conditions were investigated. The effects of the reaction temperature, methanol/oil mole ratio and catalyst concentration on biodiesel yield were considered. And the results showed optimum biodiesel yield of 99% obtained at 54°C, 7 methanol/oil mole ratio and 0.4 wt/wt % catalyst concentration. The potential emissions from both the biodiesel produced and washing water stored (for six weeks) in refrigerator (≤ 10°C), vacuum (50 kPa) and direct exposure to atmosphere were identified and quantified. Impact analysis of the emissions involved their categorization into: terrestrial acidification, freshwater eutrophication, human toxicity, terrestrial ecotoxicity, climate change and freshwater ecotoxicity. Freshwater ecotoxicity category had the most pronounced negative impact of the potential emissions with 5.237710-2 kg 1,4-DB eq. emissions in Atmosphere, 4.702610-2 kg 1,4-DB eq. emissions in Refrigerator and 3.966110-2 kg 1,4-DB eq. emissions in Vacuum. Climate change had the least effect of the emissions with 6.21410-6 kg CO2 eq. in Atmosphere, 3.9310-6 kg CO2 eq. in Refrigerator and 1.6710-6 kg CO2 eq. in Vacuum. The study showed that the order of preference of the storage environments of biodiesel is vacuum environment, refrigerated condition and exposure to atmosphere.

Production and Life Cycle Assessment of Biodiesel from ThreeWaste Oils

Abstract: Converting the huge amount of waste cooking oils presently generated globally to biodiesel as complementary energy source to fossil fuel is one of the major routes to sustainable energy management. However, producing quality biodiesel at established optimum conditions, through a clean technology with favourable environmental implications is of greater importance. This research focused on achieving the latter through alkali catalysed trans-esterification process of biodiesel production and life cycle assessment (LCA) of the biodiesel produced using SIMAPRO 7.3.3. In this research, the comparative analysis of the use of KOH and NaOH, as catalysts in the trans-esterification of Waste Groundnut Oil (WGO), Waste Soyabean Oil (WSO) and Crude Palm Kernel Oil (CPKO); as well as the life cycle assessment of the biodiesel produced from WGO, WSO and CPKO were established. The results obtained showed that, under similar conditions, biodiesel yields from the trans-esterification of oils using KOH as catalyst are higher than the yields from the NaOH catalysed process. Comparatively, the optimum conditions for biodiesel yield from KOH catalysed trans-esterification of WGO are; 10.67 methanol/oil mole ratio, 0.86 w/w Oil catalyst concentration at 600C and 71 minutes reaction time. For NaOH catalysed trans-esterification of WGO, the optimum conditions are 9.94 methanol/oil mole ratio, 0.70 w/w Oil catalyst concentration at 600C and 72 minutes reaction time. Optimum conditions for biodiesel yield from KOH catalysed trans-esterification of WSO are; 9.76 methanol/oil mole ratio, 1.04 w/w Oil catalyst concentration at 600C and 70 minutes reaction time. For NaOH catalysed trans-esterification of WSO optimum conditions are 9.00 methanol/oil mole ratio, 0.70 w/w Oil catalyst concentration at 610C and 70 minutes reaction time. The optimum conditions for biodiesel yield from KOH catalysed trans-esterification of CPKO are; 9.51 methanol/oil mole ratio, 1.24 w/w Oil catalyst concentration at 620C and 80 minutes reaction time. For NaOH catalysed trans-esterification of CPKO, the optimum conditions are 9.57 methanol/oil mole ratio, 1.10 w/w Oil catalyst concentration at 620C and 85 minutes reaction time. The accuracy of the optimal conditions obtained in all cases was justified by the optimal desirability values of approximately 1 in all cases. A simple, cost effective and energy efficient model for the prediction of biodiesel cetane number (CN) was derived. Statistical analysis showed low value of 3.28 % of Average Absolute Deviation (% AAD) for the proposed biodiesel CN model from the reported biodiesel CN model (experimental). The values of biodiesel CN calculated using the proposed model fall within ASTM specification. Analysis of the possible environmental impacts through the LCA of the biodiesels from WGO, WSO and CPKO recorded the possible emissions from the production processes as well as the products; and reports on the impacts of these emission on human health, ecosystem quality and climate change. The emission effects are potentially more pronounced on the ecosystem quality, followed by human health and least on climate change.

Comparative Study of Production and Performance of Bio-fuel Obtained from Different Non-edible Plant Oils

Abstract: The demand of fossil fuels like coal, crude oil and natural gas for transportation and power generation increases continuously. Hence, fuel crisis and environmental concern have led to look for alternative fuels. Biodiesel is an alternative renewable fuel that has properties comparable to diesel obtained from petroleum processing. The major objective of the present investigations was to select the best available feedstock’s for oil production from available non-edible plant oils. The bio-diesel of Jatropha, Mahua, Karanj, Jojoba and Neem were compared and tried for various parameters such as economy, fuel properties, engine performance and exhaust emissions and air pollution. Seed yield (Kg/ha) and oil content (%) are deciding parameter for economic aspect and various fuel properties i.e. Calorific value, kinematic viscosity and flash point have been compared for different feedstock’s. The experiment has been carried out with a B-20 blend of biodiesel in four stroke diesel engines. Engine performance compared on the basis of brake thermal efficiency, brake specific fuel consumption and brake specific energy expenditure. Exhaust emission of CO and NOx has been measured experimentally for all five feed stocks. On the basis of desire value of parameters; credits were put to each of the above five feed stocks and full credits were calculated for finding out best economical feed stocks which can be used for the yield of biodiesel.
