“…KSO biodiesel when used directly would not meet the requirements of Standard Biodiesel Indonesia, because it contains cyclopropenoid group. Cyclopropenoid is a reactive group that is easy to polymerize, making biodiesel viscous and thus could clog of fuel injection nozzle for diesel engine (Hudaya et al 2013). Trans-esterification process of KSO produces ceiba pentandra methyl ester (CPME) which is used to improve the properties of biodiesel such as viscosity, density, flash point, heating value and oxidation stability so that meet of biodiesel standard ASTM D6751 is recommended.…”

Availability of fossil fuels in the world decrease gradually due to excessive fuel exploitation. This situations push researcher to look for alternative fuels as a source of renewable energy, one of them is kapok (ceiba pentandra) seed oil. The aim this study was to know the behavior of laminar burning velocity, secondary Bunsen flame with open tip, cellular and triple flame. Premixed combustion of kapok seed oil was studied experimentally on perforated burner with equivalence ratio (φ) varied from 0.30 until 1.07. The results showed that combustion of glycerol requires a large amount of air so that laminar burning velocity (SL) is the highest at very lean mixture (φ =0.36) in the form of individual Bunsen flame on each of the perforated plate hole. Perforated and secondary Bunsen flame both reached maximum SL similar with that of ethanol and higher than that of hexadecane. Slight increase of φ decreases drastically SL of perforated and secondary Bunsen flame. When the mixture was enriched, secondary Bunsen and perforated flame disappears, and then the flame becomes Bunsen flame with open tip and triple flame (φ = 0.62 to 1.07). Flame was getting stable until the mixture above the stoichiometry. Being isolated from ambient air, the SL of perforated flame, as well as secondary Bunsen flame, becomes equal with non-isolated flame. This shows the decreasing trend of laminar burning velocity while φ is increasing. When the mixture was enriched island (φ = 0.44 to 0.48) and petal (φ = 0.53 to 0.62) cellular flame take place. Flame becomes more unstable when the mixture was changed toward stoichiometry.

“…An example of the hydrogenation process of some components found in turpentine oil is shown in Figure 2. Hydrogenation can be carried out via several methods, namely: conventional catalytic hydrogenation using high-pressure hydrogen gas; catalytic transfer hydrogenation with the help of hydrogen donor solution and solid catalyst [4]; and electrochemical hydrogenation. In this study, catalytic electrochemical (electrocatalytic) hydrogenation [5] was chosen for a number of reasons.…”

Abstract. Indonesia possesses great potential for developing renewable resources as alternative fuels. For example, turpentine oil obtained from Pinus merkusii, which contains mostly monoterpene hydrocarbons (C 10 H 16 ). The oil is highly suitable to be processed for biokerosene or even jet biofuel. It consists of hydrocarbons within the range of C 10 to C 15 . However, it contains insufficient H and thus needs to be upgraded. In the present work, electrochemical hydrogenation was used for upgrading. In the electrochemical cell, stainless steel, silver, and carbon were used alternately for the anode, while copper and silver Raschig rings were used for the cathode. An electrolyte solution of cuprous ammonium formate was utilized not only as a source of H but also to draw the unsaturated hydrocarbons into the aqueous phase. The electrolyte : oil ratio (up to 2:1), electrolyte concentration (between 0.4 and 2 M) and reaction time were varied throughout the experiments. The bromine number (unsaturation level) of the turpentine oil, which was initially 1,86 (mole Br 2 /mole), was lowered significantly to 0.69-0.90. Promising increase of smoke point values were observed from 11 mm to 16-24 mm, indicating a higher H content of the processed oil, thus making it suitable as a substitute for petroleum kerosene.

O grande físico inglês Isaac Newton um dia afirmou: "Se consegui ver mais longe é porque estava aos ombros de gigantes". É chegada hora de rever todos os momentos ao longo desses quatro anos e lembrar aquelas pessoas que fizeram a diferença e me fortaleceram para a conclusão deste trabalho. Ao meu esposo, Alex, pela força que nos une e faz do nosso amor o mais intenso e o maior. "Entre tantos outros, entre tantos séculos, que sorte a nossa, hein? Entre tantas paixões, esse encontro, nós dois, esse amor..." (Vanessa da Mata). Obrigada pela sua força, por sua dedicação, pela espera paciente nos momentos de ausência, por toda a sua capacidade de compreensão, por sua confiança em mim, enfim, pela sua presença em minha vida. Esta vitória é nossa! Aos meus filhos, Lucas e Rafael, que souberam entender minha ausência nos muitos momentos desde que ingressei no doutorado até a conclusão desta tese. Obrigado por seu amor e por me aguentarem nos momentos de ansiedade e estresse nos meses em que me dediquei ao doutorado. Mamãe está de volta! Aos meus pais, Francisco e Edith, pela sabedoria em me educar, por seus gestos solidários, pela sua espiritualidade, pelo amor e carinho de pais que souberam me proteger e me ensinar os limites da vida, por ter investido e acreditado sempre na educação e me incentivado a trilhar os caminhos do conhecimento capaz de transformar as pessoas sempre para melhor. Vocês são presença marcante em minha vida. Obrigada por me ensinar a não desistir dos meus sonhos, por acreditar em mim e por compartilhar de muitas das minhas angústias e conquistas. Amo-os muito e sempre! Ao meu querido orientador Prof. Dr. Paulo Anselmo Ziani Suarez pela dedicação, disponibilidade e pela seriedade na orientação. Sou grata por toda a compreensão e carinho que tem demonstrado por mim ao longo desta jornada. iii Aos melhores IC´s que eu poderia ter Fernando Nogueira Rocha e Isabela Castro, pela dedicação, amizade e disposição para contribuir com este trabalho.
