The Australian Government is undertaking a review of Australia’s liquid fuel security to help deliver affordable and reliable energy. The interim report with initial findings was released for public consultation in April 2019. Feedback on the interim report will inform the final report to Government in the second half of 2019. The liquid fuel security review is contributing to a broader consideration of energy security across liquid fuel, electricity and gas supplies in the National Energy Security Assessment in 2019. The National Energy Security Assessment will consider human and environmental threats to our energy markets – electricity, gas and liquid fuels.

Abstract Industrial gas turbines like the MGT6000 are often operated as power supply or as mechanical drives. In these applications, liquid fuels like 'Diesel Fuel No.2' can be used either as main fuel or as backup fuel if natural gas is not reliably available. The MAN Gas Turbines (MGT) operate with the Advanced Can Combustion (ACC) system, which is capable of ultra-low NOx emissions for gaseous fuels. This system has been further developed to provide dry dual fuel capability. In the present paper, we describe the design and detailed experimental validation process of the liquid fuel injection, and its integration into the gas turbine package. A central lance with an integrated two-stage nozzle is employed as a liquid pilot stage, enabling ignition and start-up of the engine on liquid fuel only. The pilot stage is continuously operated, whereas the bulk of the liquid fuel is injected through the premixed combustor stage. The premixed stage comprises a set of four decentralized nozzles based on fluidic oscillator atomizers, wherein atomization of the liquid fuel is achieved through self-induced oscillations. We present results illustrating the spray, hydrodynamic, and emission performance of the injectors. Extensive testing of the burner at atmospheric and full load high-pressure conditions has been performed, before verification within full engine tests. We show the design of the fuel supply and distribution system. Finally, we discuss the integration of the dual fuel system into the standard gas turbine package of the MGT6000.

Desulfurization Efficiency

A new class of green solvents, known as ionic liquids (ILs), has recently been the subject of intensive research on the extractive desulfurization of liquid fuels because of the limitation of traditional hydrodesulfurization method. In present work, eleven Lewis acid ionic liquids were synthesized and employed as promising extractants for deep desulfurization of the liquid fuel containing dibenzothiophene (DBT) to test the desulfurization efficiency. [Bmim]Cl/FeCl3was the most promising ionic liquid and performed the best among studied ionic liquids under the same operating conditions. It can remove dibenzothiophene from the model liquid fuel in the single-stage extraction process with the maximum desulfurization efficiency of 75.6%. It was also found that [Bmim]Cl/FeCl3may be reused without regeneration with considerable extraction efficiency of 47.3%. Huge saving on energy can be achieved if we make use of this ionic liquids behavior in process design, instead of regenerating ionic liquids after every time of extraction.

This study aims to discuss new and renewable energy policies as an effort to build national energy security. Research methods use legal research that searches from various perspectives. The implementation of analysis, using the method of regulatory and focus on energy, generally has many impacts. First, the policy on the use of new and renewable energy aims to prepare the carrying capacity of national energy security. Implementation this policy has not been fully implemented because there are still many obstacles faced. Second, the use of new energy and renewable energy as an effort to build national energy security in Indonesia is still not optimal. Even though Indonesia is blessed with abundant natural and energy resources in all its regions and the need for new and renewable energy as the future fate of energy security in the unitary state of the Republic of Indonesia for people's welfare as a step to reduce the increase in consumption of fossil-based energy.

<p>Liquid fuel from polystyrene waste and waste cooking oil biodiesel was successfully obtained through catalytic cracking using Al-MCM-41/Ceramic. The structure, morphology, acidity, and porosity of the catalyst were studied by SEM-EDX, pyridine FTIR, and N<sub>2</sub> gas adsorption-desorption. The products of catalytic cracking were analyzed using gas chromatogram-mass spectroscopy (GC-MS). The highest yield was obtained at feedstock variations of 57% (P): 43% (M) with the number of hydrocarbon fractions (&lt; C<sub>7</sub>) is 0.48%, hydrocarbon fraction (C<sub>8 </sub>- C<sub>12</sub>) is 20.99%, and hydrocarbon fraction (&gt; C<sub>12</sub>) is 78.53% in the cracking time 1 hours. Physical characteristics were reported in the form of density, flash point, and caloric value respective. The performance of liquid fuels with commercial fuels, Premium (RON 88), and additives of methyl tertiary butyl ether (MTBE) comparisons of 225 (mL): 750 (mL): 18.25 (mL) respectively produce thermal efficiency on engine use gasoline generator sets was 28.22% at the load of 2118 Watts. Based on this research, all variations of feedstock produce liquid fuels that are in accordance with SNI 06-3506-1994 concerning the quality of gasoline fuel types.</p><p> </p>Keywords: Catalytic cracking, polystyrene waste, waste cooking oil, liquid fuel

AbstractThis study aims to determine the implementation of new energy and renewable energy policies in the context of national energy security. The research method used is legal research that uses a regulatory approach. The results of the study show that the implementation of new energy and renewable energy policies in the context of national energy security has proceeded as it should. This can be seen from the role of the government in making policies (beleid) and management actions (bestuursdaad), arrangements (regelendaad), management (beheersdaad) and supervision (toezichthoudensdaad) for the purpose of maximizing the people's prosperity.

Increased ignition probabilities of ethanol are found on a heated hot-plate with the introduction of Al2O3, Fe3O4, and carbon nanotube (CNT) nanoparticle suspensions. We show that the mechanism is probably due to liquid fuel boiling point elevation caused by nanoparticle accumulation at liquid–vapor interfaces. The magnitudes of this impact are related to the number and geometry of nanoparticles but independent from the nanoparticle chemical compositions. These findings may have important applications for developing future alternative liquid fuels with advanced combustion characteristics.

Abstract A series of experiments was performed to investigate the spreading behavior of firefighting foam solutions on liquid fuel surfaces. The spreading coefficients of six kinds of aqueous film-forming foam solutions and one fluorine-free foam solution on the surface of four liquid fuels, namely, cyclohexane, diesel, n-heptane, and ethanol, were calculated on the basis of surface and interfacial tension. Spreading behavior was studied systematically using a high-speed camera, and then the relationship between spreading behavior and spreading coefficient was analyzed. Furthermore, the spreading area and spreading rate of different foam solution droplets on liquid fuel surfaces were studied in depth. The spreading amount of the foam solution droplets on the liquid fuel surfaces was measured. Four typical spreading phenomena, namely, spreading, suspension, dissolution, and sinking, of AFFF solutions on liquid fuel surfaces were identified. Moreover, a positive spreading coefficient did not necessarily lead to the formation of an aqueous film. The spreading area, spreading rate, and spreading amount were not proportional to the spreading coefficient. During the evaluation of the spreading property of firefighting foam, the spreading coefficient, spreading rate, and spreading amount must be focused on instead of only the spreading coefficient.
