Palm Oil Biodiesel

Palm oil is comparable to traditional diesel fuel in terms of calorifi c value, stoichiometric ratio, and cetane number. However, its increased kinematic viscosity and pour point make it diffi cult to use in pure form in diesel engines. (Research purpose) To study specifi c features of burning: diesel fuel with various additives of palm oil (biodiesel fuel); pure 100-percent palm oil; biodiesel fuel with various additives of palm oil and hydrogen peroxide, as well as to develop a method to control its combustion process. (Materials and methods) To determine the ignition time lag, the authors chose a method of kinetic modeling of self-ignition of biodiesel fuel in the air. The self-ignition process was simulated using the Chemical Workbench software package. An adiabatic calorimetric bomb model was used to perform calculations. To describe the process of self-ignition, a universal kinetic mechanism was used, which was verifi ed to calculate self-ignition of diesel and biodiesel fuel surrogates, as well as the formation of toxic substances and soot in the combustion processes. (Results and discussion) It is shown that adding palm oil to diesel fuel increases its ignition time lag, especially at low and medium temperatures of 750-950 kelvin. It was determined that with addition of 10 percent palm oil, the ignition time lag of biodiesel fuel is almost the same as that of diesel fuel no more than 5 percent. Increasing the amount of palm oil additive up to 30 percent and more signifi cantly increases the ignition time lag of the fuel. When using only palm oil as a fuel, the ignition time lag in the temperature range of 800-950 kelvin increases in two times. The study determined the optimal amount of hydrogen peroxide to be used for each composition of biodiesel fuel with various additives of palm oil. (Conclusions) It is shown that additives of hydrogen peroxide can infl uence the reactivity of biodiesel fuel and thereby regulate its ignition time lag.

In order to reduce the use of fossil fuel without interfering the availability of food crop, Cerbera manghas biodiesel has been studied as potential renewable fuel. This study investigated Cerbera manghas biodiesel as a replacement for pure petro-diesel and palm oil biodiesel produced in Indonesia. The investigation result indicates that Cerbera manghas biodiesel fuel has a lower density, kinematic viscosity, sulfur content, color (lighter), water content, distillation point compared to pure petro-diesel and palm oil biodiesel. Higher flash point and cetane index value in Cerbera manghas biodiesel were also discovered. The study investigated further the effect of biodiesel derived from Cerbera manghas biodiesel compared with pure petro-diesel and palm oil biodiesel in a single cylinder diesel engine. The study suggested that Cerbera manghas biodiesel has better engine performance (fuel consumption, brake mean effective pressure, thermal efficiency, torque, and power) compared to pure petro-diesel and palm oil biodiesel. The utilization of Cerbera manghas biodiesel gave better engine performance output compared to pure petro-diesel and palm oil biodiesel. This study supported the viability of Cerbera manghas biodiesel to be implemented as an alternative diesel fuel without interfering food resources or requiring additional modification to the existing diesel engine.

The article presents the results of study to determine the component composition of rape-based biodiesel. Modeling of the optimal component composition taking into account low-temperature properties and cetane number was carried out. According to the studies, mathematical models of changes in the low-temperature properties of biodiesel fuel depending on the percentage of rapeseed oil were obtained, the optimal ratio of its components was determined and justified. The tests were conducted in 2012-2019. The studied temperature limits correspond to the extreme temperature values of the central and southern regions of the Russian Federation. The second important task was to determine the optimal ratio of diesel fuel and rapeseed oil while meeting the requirements of GOST R52368-05 for the cetane number of biodiesel fuel. Studies of the optimal percentage ratio of rapeseed oil and diesel fuel per cetane number showed that biodiesel, which contains rapeseed oil in a concentration of up to 30 %, meets the requirements of GOST R52368-05 (EN 590:2009). Certified equipment was used in the studies, and the methodology met the requirements of the state standard for their implementation. To solve the problem of determining the optimal ratio of biodiesel components, a methodology for assessing temperature and cetane number properties, as well as foreign scientific literature was analyzed in the field of research data. According to the results of the research, hypotheses were put forward that the lowtemperature properties and cetane number of biodiesel fuel change with an increase in the proportion of rapeseed oil in it, as well as the possibility of mathematical modeling of its optimal component composition corresponding to environmental temperature conditions during operation of the equipment. The reliability of the approximation of the obtained dependences was 0.83...0.91 when studying the low-temperature properties of biodiesel samples within the specified temperatures from -40 to 0 °C.

This study examined the use of waste plastic oil (WPO) combined with biodiesel as an alternative fuel for diesel engines, also commonly known as compression ignition engines, and focused on comparison of the basic physical and chemical properties of fuels, engine performance, combustion characteristics, and exhaust emissions. A preliminary study was conducted to determine the suitable ratio for the fuel blends in consideration of fuel lubricity and viscosity, and these results indicated that 10% biodiesel—derived from either palm oil or castor oil—in waste plastic oil was optimal. In addition, characterization of the basic properties of these fuel blends revealed that they had higher density and specific gravity and a lower flash point than diesel fuel, while the fuel heating value, viscosity, and cetane index were similar. The fuel blends, comprised of waste plastic oil with either 10% palm oil biodiesel (WPOP10) or 10% castor oil biodiesel (WPOC10), were selected for further investigation in engine tests in which diesel fuel and waste plastic oil were also included as baseline fuels. The experimental results of the performance of the engine showed that the combustion of WPO was similar to diesel fuel for all the tested engine loads and the addition of castor oil as compared to palm oil biodiesel caused a delay in the start of the combustion. Both biodiesel blends slightly improved brake thermal efficiency and smoke emissions with respect to diesel fuel. The addition of biodiesel to WPO tended to reduce the levels of hydrocarbon- and oxide-containing nitrogen emissions. One drawback of adding biodiesel to WPO was increased carbon monoxide and smoke. Comparing the two biodiesels used in the study, the presence of castor oil in waste plastic oil showed lower carbon monoxide and smoke emissions without penalty in terms of increased levels of hydrocarbon- and oxide-containing nitrogen emissions when the engine was operated at high load.

Avocado (Persea americana Mill) is a popular fruit in Indonesia. Its popularity leads to high consumption of this fruit and wastes from its seed. In order to develop renewable energy and reducing wastes in the environment, P. americana seed may be extracted for its oil to create biodiesel fuel. In this study, P. americana seed is obtained through the soxhlet apparatus and transesterification process. After obtaining P. americana seed oil, the oil was mixed with pure petro-diesel with a ratio of 10:90 (B10 fuel) and 20:80 (B20 fuel), respectively. These fuels were tested for their fuel characteristics and engine performances, together with pure petro-diesel and palm oil biodiesel. The fuel characteristics results suggest positive characteristics of B10 and B20 compared to other fuels. For engine performance tests, B10 and B20 fuels have less engine performance than other fuels. However, the differences between these fuels results are small. Overall, the positive aspect of B10 and B20 fuels supersede small disadvantages they have and thus suitable to substitute pure petro-diesel and palm oil biodiesel.

Palm Oil Biodiesel

Biodiesel is known for its high cetane number and high oxygen content among other advantages, but its high viscosity and density are not trivial issues for fuel flow and atomization, especially under idling conditions. Due to low cylinder temperature and incomplete combustion, engine idling is one of the worst operating conditions. As a common fuel additive, ethanol can address some of the shortcomings of biodiesel. This work evaluated the combustion and emission characteristics of different concentrations of ethanol additives on a diesel engine fueled with palm oil biodiesel under idling conditions. The results show that ethanol helps to increase peak cylinder pressure and heat release rate, suppressing the production of certain emissions with a maximum reduction in smoke opacity of 71%.
