“…Much of this research, however, is in the initial stages, and is not ready for commercialization, while first-generation biofuel has been mastered for converting feedstock to liquid biofuel. Infrastructure and technology for second-and third-generation biofuels are still lacking [30,31]. In general, related technology processes have a high-capability cost and are less energy-efficient.…”

In this study, various national strategies and programs are described by planning instruments. The TIEB (Thailand Integrated Energy Blueprint), which includes six programs (AEDP, PDP, EEDP, ODP, GDP, REDP), aims to regulate renewable energy and improve the use of biofuel. In addition, the potential of second-generation biofuels is estimated with different residue extractions of second-generation biomasses: 20% (scenario 1), 44% (scenario 2), and 66% (scenario 3). Based on the production potentials that were estimated, CO2 will decrease 1.3–3.5 megatons in the gasoline sector, and 1.4–3.8 megatons in the diesel sector under scenario 1. In scenario 2, we estimated decreases of 2.8–7.7 mega tons and 3.2–8.4 mega tons of CO2 for the gasoline and diesel sectors, respectively. Finally, scenario 3 is expected to reduce the CO2 concentration by 4.2–11.6 megatons in the gasoline sector, and by 4.7–12.6 megatons in the diesel sector. We also estimate the economic potential of a second-generation biofuel with the view of emissions trading. For bioethanol and biodiesel, respectively, 27–74 million USD and 30–81 million USD could be realized in scenario 1, 60–163 million USD and 67–178 million USD in scenario 2, and 90–244 million USD and 100–267 million USD in scenario 3. We conclude that the future potential of second-generation biofuels in Thailand is optimistic, and that they can provide both environmental and economic benefits to the country.

“…The last category of biofuel offers a more promising alternative than the two previous ones, that pose problems related to the cultivable surfaces and especially of famine due to the rise in prices of some staple foods, such as maize, soy, wheat, rapeseed, sunflower, and palm. Indeed, biofuels are separated into alcohol which is primarily used in the spark-ignition engine "gasoline engine", and esters which are employed in compression ignition engines "diesel engine" [8], [9]. Bioethanol is obtained from vegetable raw materials.…”

Nowadays, the possibility of substituting gasoline fuel with biofuels is examined by numerous researchers. This paper discusses the numerical study of the biofuel model (methyl decanoate). The Fluent code was used to validate the comparison between the non-premixed gasoline (n-decane) and biofuel model (methyl decanoate) combustion in the same conditions. The turbulence model used was the realizable k- model. The aerothermochemistry equations and the transport model of chemical species (Eddy-dissipation) were implemented in the combustion reaction to develop the velocity, pressure, temperature, energy, enthalpy, the turbulence dissipation rate, the kinetic energy of the turbulence, and the mass fraction of the species. The results showed that the CO 2 and NO X contents of methyl decanoate are 5.7% and 11.03% respectively higher than those of decane.

“…They belong to renewable energy sources, the use of which has accompanied humanity from the earliest times [22,23]. In general, the biofuels can be divided into alcohols and esters [24,25]. The former (most often produced from cereals, maize, potatoes and sugar beet) are alternative fuels for gasoline (low-pressure) engines [26,27].…”

The Effects of Pressure and Temperature on the Process of Auto-Ignition and Combustion of Rape Oil and Its Mixtures

et al. 2019

The effects of initial pressure and temperature in a constant volume test chamber with a common rail injection system on the processes of self-ignition and combustion of rapeseed oil and various blends of rapeseed oil with diesel oil are explored. Based on the obtained pressure waveforms the amount of emitted heat was determined, and the tested fuels were compared. The variations of a number of physicochemical characteristics that occur during the combustion processes were evaluated for several mixtures of fuel components. It was found that in the case of blends of rapeseed oil with diesel oil, the best results were obtained for a mixture containing 70 weight percent of diesel oil and 30% of rapeseed oil.
