CHEMICAL AND PHYSICAL INFORMATION 3.1 CHEMICAL IDENTITY Information regarding the chemical identity of fuel oils is located in Table 3-l. Information on the composition of selected fuel oils, specifically fuel oil no. Researchers have shown that physical and chemical properties of biofuels may vary significantly depending on their chemical composition, thus affecting engine performance and exhaust emissions. Gasoline or petrol is a fuel, derived from petroleum crude oil, for use in spark-ignited internal combustion engines. Create a custom chart comparing fuel properties and characteristics for multiple fuels. Petroleum is a very complex mixture of organic compounds which are chiefly hydrocarbons, that is, compounds composed of hydrogen and carbon. Abstract. 2 3 Resid or residuum is the residue that remains when crude oil is distilled. Although the hydrocarbons are the chief constituents … Types of Fuels: Diesel fuel can be described by its cetane number, which is a measure of ignition quality inversely proportional to the octane number for gasoline. a��:n?�ڢ*����'����f��}�|e�Ԇg+���*Z@��rs�DJP�WVVIe�H�2e�ُV�Qg?J��8���(���$Vq\��(�S�K� Its chemical properties make it useful as a fuel or in some cases, as a solvent, making it similar to kerosene. When provided with an ignition source, fuel ignites or flashes at its flash point. Chemical fuels are divided in two ways. Authors; Authors and affiliations; Hendrik A. Romp; Chapter. However, most of the times, combustion properties are also assigned to fuels, in spite of the fact that these properties depend on the oxidiser (e.g. Clear all.

The mixture is easily adjustable at all flame stages. Also, three temperature dependent physical property targets were selected, including liquid density, viscosity, and surface tension. The viscosity of a liquid refers to its resistance against being deformed by shear forces. A high temperature fuel gas/oxygen flame produces a quick increase of temperature on the surface of the work piece. Three of the property targets are chemical in nature, including CN, LHV and H/C. This paper discusses the physical−chemical properties of ethanol−biodiesel blends considered as fuel for diesel engines.

Learn more about fuel cells in this article. Submit Guest Post They consist predominantly of C9–C16 hydrocarbons that are a combination of n-paraffins, isoparaffins, naphthenes, and aromatics. The so-called chemical elementary analysis shows that generally fuel oils consist of about 85 to 90% of carbon, 13 to 8% of hydrogen and a small percentage of sulphur, oxygen and nitrogen, but two fuel oils of the same elementary analysis may behave in quite a different manner in burning practice, so that this chemical analysis is really of very little value. Density, kinematic viscosity, distillation characteristics, heating values, water content, flash point, cold filter plugging point, lubricity, autoignition properties, and corrosiveness to copper were tested. An ideal fuel is cheap. The properties of diesel fuel are at times varied from other fuels such as gasoline, however there are also some similarities such as the fact that they both burn in a fuel cylinder to make the engine work and it goes without saying that they both power vehicles. Fuel cell, any of a class of devices that convert the chemical energy of a fuel directly into electricity by electrochemical reactions. << /Length 6 0 R /Filter /FlateDecode >> Low calorific value and require large excess air. Artificial or secondary fuels are prepared from primary fuels charcoal, coal gas, coke, kerosene oil, diesel oil, petrol, etc. A fuel cell resembles a battery in many respects, but it can supply electrical energy over a much longer period of time. Gasoline might of course simply be a straight run distillate from crude oil. Some critics argue that it is mainly a government subsidy for corn-growing agribusiness. Conventional gasoline is mostly a blended mixture of more than 200 different hydrocarbon liquids ranging from those containing 4 carbon atoms to those containing 11 or 12 carbon atoms. air, pure oxygen) and the actual process (e.g. 72 may serve as a simple scheme for the distillation of crude oil. A flash point is defined to minimise fire risk during normal storage and handling. Effects of fuel physical and chemical properties on combustion and emissions were investigated on both metal and optical diesel engines. The Physical Properties of Fuel Oil. The fuel properties needed to keep a lamp burning are not nearly as stringent as those required to keep a jet aircraft aloft. 5 0 obj Fuel Properties Flash point The flash point of a fuel is the temperature at which vapour given off will ignite when an external flame is applied under specified test conditions. The Archer Daniels Midland Corporation of Decatur, Illinois, better known as ADM, the world's largest grain processor, produces 40% of the ethanol used to make gasohol in the U.S.. … fuel physical properties on ignition delay and burning rates at various engine operating conditions. Vinodh Reddy is an Editor-in-chief of ME Mechanical. All Rights Reserved. In this study, the physical and chemical properties of blends of standard diesel fuel and 1-butanol were tested, with 1-butanol volume fractions of up to 25%. %PDF-1.3 Fuel properties The ethanol used in the tests was limited to essentially anhydrous ethanol because other kinds of ethanol are not soluble or have very limited solubility in the vast majority of diesel fuels. bul��9Ro�b6����T���������/2�]������qw���=$�w��O���D8b�m���kX��4d &��=� -$�E`�� c9�Z���Ͷ*�V~�H��Y�i�Kg�S�$F�]���~�s��� �ԟ��f��>ᄬJ��p�ϒ�M^��q}.Q���[Iu�jDg������3��%@K-n�(pw��O���KV>�w���w��Xꊼ�Ve��q�r�m�$������T��m�*;���7�Fo��۩�ka������\)���Oڋ������Ñ�:�+ՠŃ[������.�1�Bʶ�o&}�Ws u����z��_�����~w�U�ES$�7��[�f����ے�"������X&���������������� j �[OT�n�,�1_�g�$Z���S��U8��xH^`���3H7�0O�����W]��i�~^%�V.��\&�M�4�/^߿Z�W�k,B�?���7m���W����0�Kҫ�O�“����ʊ�2��B�ճ���q�a���(��)]�9�>�/^���Y>�LJ)���\����a��U��n�UN��� �_ՠ���:PZ�ۦr�e8��WW��l>�h��kB��p5ɝ�7~}���`�fMBe�U�y���Fo����n�寿�1Q Fuels under... Density. Products with similar physical properties should not be used interchangeably without a complete understanding of the requirements of their intended use. Diesel Fuel Properties and Characteristics (Part 1) Rudolf Diesel would be proud of the global acceptance of, and dramatic improvements made to, the diesel engine over the past 100 years. Secondly, on the basis of their occurrence: primary (natural fuel) and secondary (artificial fuel). Fuel properties explained very clearly . An ideal fuel burns easily in the air at a moderate rate. It is the simplest alcohol, and is a light, volatile, colorless, flammable, liquid with a distinctive odor that is very similar to but slightly sweeter than ethanol (drinking alcohol). Arguments in favor of ethanol are the search for decreased dependency on oil producing countries and the decreased net ouptut of the greenhouse gas carbon dioxide. In summary, the composition of Jet A/A-1, JP-5, and JP-8 are very similar. Increasingly important is FCC – fluid catalytic cracked – gasoline. An ideal fuel should have the following properties: High calorific value Moderate ignition temperature Low moisture content Low NO n combustible matter Moderate velocity of combustion Products of combustion not harmful Low cost Easy to transport Combustion should be … Thus, a general classification of chemical fuels is: MW is a temperature independent physical property. Great article Vinodh ! Topic: Hydrocarbon. Some properties of ideal fuel are: An ideal fuel is readily available. Learn how your comment data is processed. It might have been blended with reformed naphtha as an extender, and it might have had octane enhancers added. Fuels, as for any other type of substance, can be assigned some physical and chemical properties (e.g. Coal - Coal - Structure and properties of coal: The plant material from which coal is derived is composed of a complex mixture of organic compounds, including cellulose, lignin, fats, waxes, and tannins. The data are reported to EPA for every batch of gasoline produced at the refinery, blended at terminals or imported into to the U.S., and sold in the U.S. Privacy Policy (l) ARCO Chemical Company, 1987. A fuel gas/air flame works with a lower temperature (due to the amount of nitrogen in the air). Calorific value of fuel is the total quantity of heat liberated when a unit mass or volume of fuel is completely burnt. Tag Index The solubility of ethanol in diesel fuel is dependent on the hydrocarbon composition, wax content and ambient temperature of the diesel fuel. Selection of an Appropriate Factor of Safety, High Pressure Boilers: Features and Advantages, Merits and Demerits of Water Tube Boiler over Fire Tube Boiler, Interview Questions on Material Science and Engineering. Natural or primary fuels are found in nature such as wood, peat, coal, natural gas, petroleum. Select the fuel and properties of interest. The diagram of fig. 87 Downloads; Abstract. Diesel engines were developed to take advantage of the high energy content and generally lower cost of diesel fuels. The results presented here are compiled from data reported to EPA by refiners and importers to verify compliance with EPA’s gasoline fuel quality standards. Subject: Chemistry. Fuel gas properties. Higher or gross calorific value (HCV) in the total amount of heat produced when a unit mass/volume of fuel has been burnt completely and the products of combustion have been cooled to room temperature (15°C or 60°F).
