Abstract

This article analyzes two ways of solving environmental problems in the fuel industry, which arose due to the need to stabilize the concentration of greenhouse gases in the atmosphere. According to the first direction, the ways of using various non-traditional types of raw materials and waste containing sugars for the purpose of producing environmentally friendly types of fuel are considered. According to the second direction, the possibilities of integrated use of ethanol and all by-products formed during its production are analyzed to improve ecology in the fuel industry. We have established the possibility of using the by-products of ethanol production, fuel oil and fuel alcohol, to improve the operational properties of motor fuels used in carburetor and diesel engines. It has been stated that the additives of fuel alcohol and fuel oil increase the octane number of gasoline, improve its fractional composition, as a result of which the completeness of fuel combustion and the uniformity of its supply to the engine cylinders increase. The optimal concentrations of alcohol additives to gasoline are as follows: 5 vol.% and 10 vol.% for fuel alcohols and fuel oil, respectively. It has been established that the addition of fuel oil to diesel fuels increases their cetane number, this causes the mixture to ignite faster and the diesel engine to start. Moreover, with the addition of fuel oil, the temperature of the beginning of boiling decreases which facilitates the starting properties of the fuel, and the viscosity of the fuel mixture decreases which improves the completeness of mixing and transportation in the engine system. The optimal concentration of fuel oil additive to diesel fuel is 10 vol.%.

乙醇生产副产物在燃料工业中的应用

本文分析了解决燃料工业环境问题的两种方法，这是由于需要稳定大气中温室气体的浓度而产生的。根据第一个方向，考虑了利用各种非传统类型的原材料和含糖废物生产环境友好型燃料的方法。根据第二个方向，分析了综合利用乙醇及其生产过程中产生的所有副产品以改善燃料工业生态的可能性。我们已经确定了使用乙醇生产的副产品、燃料油和燃料酒精来改善化油器和柴油发动机中使用的汽车燃料的运行特性的可能性。已经指出，燃料酒精和燃料油的添加剂增加了汽油的辛烷值，改善了汽油的分馏成分，从而提高了燃料燃烧的完整性和向发动机气缸供应的均匀性。汽油中醇类添加剂的最佳添加浓度为:燃料醇和燃料油的添加浓度分别为5%和10%。已经确定，在柴油中加入燃料油会增加其十六烷值，从而使混合物更快地点燃并使柴油机启动。此外，随着燃料油的加入，开始沸腾的温度降低，有利于燃料的启动性能，并且燃料混合物的粘度降低，提高了混合和运输在发动机系统中的完整性。柴油中燃料油添加剂的最佳添加浓度为10%。

期刊介绍： Voprosy Khimii i Khimicheskoi Tekhnologii (Issues of Chemistry and Chemical Technology) is published bimonthly by the Ukrainian State University of Chemical Technology and accepts Ukrainian- or English language high-quality original articles and reviews concerning various fields of research in chemistry and chemical engineering. Our unusual title “Voprosy khimii i khimicheskoi tekhnologii” originates from the transliterated initial Russian title “Issues of Chemistry and Chemical Technology“. The fact of the matter is that Voprosy khimii i khimicheskoi tekhnologii was founded in 1965 as a scientific journal mainly for Russian-reading and Russian-speaking readership when «the Iron Curtain» existed. Since 1991, after Ukraine declared its independence, our Journal began to publish the articles in Ukrainian and English. Multilingualism is our established tradition. We remember and cherish our traditions, but we follow the latest trends in modern science. Papers that are multidisciplinary or address new or emerging areas of chemistry and chemical engineering are particularly encouraged. Thus, the scope is dynamic. It includes but is not limited to the traditional areas of general, inorganic, organic, analytical, physical chemistry and electrochemistry, as well as all conventional areas of chemical engineering (chemistry of high molecular compounds, technology of inorganic and organic substances, processing of combustible minerals, chemical technology of silicates, processes and apparatus of chemical productions, etc.). The Journal publishes papers dealing with newer interdisciplinary areas such as materials science, nano-science, catalysis, computational and theoretical chemistry, surface phenomenon and colloidal systems, environmental chemistry, green chemistry.
