Carboxylic acids are traditionally produced from fossil fuels and have significant applications in the chemical, pharmaceutical, food, and fuel industries. Significant progress has been made in replacing such fossil fuel sources used for production of carboxylic acids with sustainable and renewable biomass resources. However, the merits and demerits of each carboxylic acid processing platform a...

To carry out the investigation, a cylinder pressure model was developed based on the position of the crankshaft, engine load, engine speed, and fuel injection time. This model takes into account the maximum number of parameters involved. The accuracy of the model was verified by experimental results. The average error of the cylinder pressure, the average radical of the square of the error of t...

An experimental study is performed to investigate the fuel impingement on cylinder walls and piston top inside a directinjection spark-ignition engine with optical access to the cylinder. Three different fuels, namely, E85, E50 and gasoline are used in this work. E85 represents a blend of 85 percent ethanol and 15 percent gasoline by volume. Experiments are performed at different load condition...

barrels of oil equivalent (boe) The total energy content of a non-petroleum-based product or fuel in GJ divided by 5.904 6.115 GJ/boe. biodiesel The methyl or ethyl esters of transesterified triglycerides (lipids, fats, cooking greases) from biomass. biofuel A solid, gaseous, or liquid fuel produced from biomass. biogas A medium-energy-content gaseous fuel, generally containing 40 to 80 volume ...

The PUREX technology based on aqueous processes is currently the leading reprocessing technology in nuclear energy systems. It seems to be the most developed and established process for light water reactor fuel and the use of solid fuel. However, demand driven development of the nuclear system opens the way to liquid fuelled reactors, and disruptive technology development through the applicatio...

Solar energy provides an unprecedented potential as a renewable and sustainable resource will substantially reshape our future economy. It is not only useful in producing electricity but also (high-temperature) heat fuel, both required for non-electrifiable services. Fuels are particularly valuable they dense storable, can act feedstock the chemical industry. Technical pathways processing of so...
