Calophyllum inophyllum l a prospective non edible biodiesel feedstock study of biodiesel production properties fatty acid composition blending and engine performance
Renewable & Sustainable Energy Reviews, 2014Co-Authors: A E Atabani, Aldara Da Silva CesarAbstract:Recently, non-edible oil resources are gaining worldwide attention because they can be found easily in many parts of the world especially wastelands that are not appropriate for cultivating food crops, eliminate competition for food, more efficient, more environmentally friendly, produce useful by-products and they are more economical compared to edible oils. Jatropha curcas, Pongamia pinnata, Calophylium inophyllum, Croton megaiocarpus and Azadirachta indica are some of the major non-edible feedstocks for biodiesel production. This paper investigates the potential of Calophyllum inophyllum as a promising feedstock for biodiesel production. In this paper, several aspects such as physical and chemical properties of crude Calophyllum inophyllum oil and methyl ester, fatty acid composition, blending and engine performance and emissions of Calophyllum inophyllum methyl ester were studied. Overall, Calophyllum inophyllum appears to be an acceptable feedstock for future biodiesel production. (C) 2014 Elsevier Ltd. All rights reserved.

Effect of synthetic antioxidants on storage stability of Calophyllum inophyllum biodiesel
Materials Research Innovations, 2014Co-Authors: I.m. Rizwanul Fattah, Haji Hassan Masjuki, Abul Kalam, B.m. MasumAbstract:Biofuels, especially biodiesels derived from renewable sources, are becoming increasingly important because of environmental and energy concerns. However, biodiesels composed of long chain unsaturated fatty acid esters are prone to oxidation. One such biodiesel is non-edible high acid value Calophyllum inophyllum oil-based biodiesel produced through a two-stage esterification process and one-stage transesterification process. In this study, the oxidation stability of biodiesel treated with three prominent antioxidants, namely pyrogallol, propyl gallate and tert-butylhydroxyquinone was evaluated. The induction period of biodiesel with or without antioxidant was measured according to the EN14112 standard using a Rancimat instrument. Antioxidants were added at 500 ppm, which in general improved the induction period. The samples were kept for 70 days and different properties that change during storage, namely induction period, density and kinematic viscosity were monitored. For all samples, oxidation stability decreased and kinematic viscosity increased because of the formation of oxidation products. Pyrogallol showed the best effect in retaining oxidation stability of Calophyllum inophyllum biodiesel.

biodiesel conversion from high ffa crude jatropha curcas Calophyllum inophyllum and ceiba pentandra oil
Energy Procedia, 2014Co-Authors: A S Silitonga, Teuku Meurah Indra Mahlia, Haji Hassan Masjuki, W T ChongAbstract:Abstract Biodiesel is a renewable energy that has great potential as an alternative fuel to fossil diesel in diesel engine. The potential non-edible feedstock for biodiesel is now being taken into careful consideration for the purpose of continuing biodiesel production while not negatively affecting the food issue. The crude jatropha curcas , Calophyllum inophyllum and ceiba pentandra oil have free fatty acid value which is above 2%. Therefore, a pretreatment acid catalyzed esterification process is required to reduce the free fatty acid content. It was found that jatropha curcas , Calophyllum inophyllum and ceiba pentandra oil at 9:1 M ratio (methanol to oil) with preheat at 60 °C and reaction at temperature 55 °C for 60 minutes in the presence of 1% KOH in order to get lower acid values (0.39 mg KOH/g, 0.45 mg KOH/g and 0.40 mg KOH/g) and obtained high methyl ester yield (98.23%, 98.53% and 97.72%). This study had shown that improvement in biodiesel properties by using two stage esterification-transesterification methods. The major fuel characteristics such as kinematic viscosity, density, flash point and calorific value of biodiesel fulfilled American Society for Testing Materials (ASTM) biodiesel standards.

comparison of palm oil jatropha curcas and Calophyllum inophyllum for biodiesel a review
Renewable & Sustainable Energy Reviews, 2011Co-Authors: Haji Hassan Masjuki, Teuku Meurah Indra Mahlia, R. S. NorhasyimaAbstract:The world today is faced with serious global warming and environmental pollution. Besides, fossil fuel will become rare and faces serious shortage in the near future. This has triggered the awareness to find alternative energy as their sustainable energy sources. Biodiesel as a cleaner renewable fuel has been considered as the best substitution for diesel fuel due to it being used in any compression ignition engine without any modification. The main advantages of using biodiesel are its renewability and better quality of exhaust gas emissions. This paper reviews the production, performance and emission of palm oil, Jatropha curcas and Calophyllum inophyllum biodiesel. Palm oil is one of the most efficient oil bearing crops in terms of oil yield, land utilization, efficiency and productivity. However, competition between edible oil sources as food with fuel makes edible oil not an ideal feedstock for biodiesel production. Therefore, attention is shifted to non-edible oil like Jatropha curcas and Calophyllum inophyllum. Calophyllum inophyllum oil can be transesterified and being considered as a potential biodiesel fuel. Compared to Palm oil and Jatropha biodiesel industry, biodiesel from Calophyllum inophyllum is still in a nascent state. Therefore, long term endurance research and tribological studies need to be carried out before Calophyllum inophyllum oil base biodiesel can become an alternative fuel in future.

the performance and exhaust emissions of a diesel engine fuelled with Calophyllum inophyllum palm biodiesel
Processes, 2019Co-Authors: Natalina Damanik, Teuku Meurah Indra Mahlia, A S Silitonga, M Mofijur, Chong Wen Tong, Abd Halim Shamsuddin, A H Sebayang, Chintsan Wang, Jerhuan JangAbstract:Nowadays, increased interest among the scientific community to explore the Calophyllum inophyllum as alternative fuels for diesel engines is observed. This research is about using mixed Calophyllum inophyllum-palm oil biodiesel production and evaluation that biodiesel in a diesel engine. The Calophyllum inophyllum–palm oil methyl ester (CPME) is processed using the following procedure: (1) the crude Calophyllum inophyllum and palm oils are mixed at the same ratio of 50:50 volume %, (2) degumming, (3) acid-catalysed esterification, (4) purification, and (5) alkaline-catalysed transesterification. The results are indeed encouraging which satisfy the international standards, CPME shows the high heating value (37.9 MJ/kg) but lower kinematic viscosity (4.50 mm2/s) due to change the fatty acid methyl ester (FAME) composition compared to Calophyllum inophyllum methyl ester (CIME). The average results show that the blended fuels have higher Brake Specific Fuel Consumption (BSFC) and NOx emissions, lower Brake Thermal Efficiency (BTE), along with CO and HC emissions than diesel fuel over the entire range of speeds. Among the blends, CPME5 offered better performance compared to other fuels. It can be recommended that the CPME blend has great potential as an alternative fuel because of its excellent characteristics, better performance, and less harmful emission than CIME blends.
