| Summary: | Title screen Renewable fuels require extensive research because they have specific limitations for use in engines and industrial power generation systems. In this work, comprehensive tests were performed for 24 diesel-based fuels with liquid additives derived from seed oils and wood. Additives to commercial diesel fuel included FAMEs of distilled tall, rapeseed, camelina, waste cooking oils, as well as these oils in their original form. The share of the additive varied from 5 to 15%. The corrosion activity of mixed fuels was higher than that of diesel fuel—both the average corrosion rate and morphological changes in the surface of contacting materials increased. An increase in the proportion of all types of oils in diesel fuel led to a decrease in the maximum reaction rate. Among biodiesel additives, rapeseed oil FAME provided the conversion kinetics closest to diesel fuel. The best combustion performance in a laboratory furnace was demonstrated by mixtures with additives of FAMEs of distilled tall oil and rapeseed oil with a share of 10%. In particular, adding 10% distilled tall oil FAME provided an increase in the CO2/CO ratio by 2.6 times compared to diesel fuel. In engine tests, diesel fuel showed better combustion quality than all the tested blends. However, the blend “95% diesel fuel, 5% distilled tall oil FAME” was the closest to diesel fuel, having an 11% lower CO2/CO ratio at an idle mode. The integral fuel efficiency, calculated based on a combination of technological parameters and cost, decreased by 2–16% with an increase in the share of vegetable oil or its FAME from 5% to 15%. The most promising FAME concentration in diesel fuel is 5–10% that provides the efficiency comparable to diesel fuel, moderate cost increase and carbon footprint reduction Текстовый файл AM_Agreement |
