Combustion and Emission Performance of CO/NO_x/SO_x for Green Diesel Blends in a Swirl Burner

Abstract

Green diesel is one of the alternative energy sources, which is found to be a second-generation biofuel. Green diesel has a similar molecular structure to petroleum diesel but has better diesel properties, sustainability, and environmental benignity. In this study, green diesel was synthesized from waste cooking oil via a deoxygenation reaction process and blended with petroleum diesel to assess the rate of greenhouse gas emissions. The fuel properties of the formed G100 (pure green diesel) were investigated, and the performance of G5 and G20 (a mixture of 5 and 20% green diesel in petroleum diesel) was tested for combustion in an oil burner. The overall test showed that the combustion of the blends of green diesel produced lower CO2 and SO2 emissions than that of petroleum diesel as a result of the rich oxygen-free fuel content. The obtained fuel properties of pure green diesel and blended green diesel are in compliance with ASTM D6751, ASTM D240-17, and EN 14214 standards. Based on these findings, it is shown that blended green diesel is a clean fuel for the environment and a promising alternative fuel for internal combustion engines.

A Short Review on Catalyst, Feedstock, Modernised Process, Current State and Challenges on Biodiesel Production

“…Key benefits of biodiesel are that it is neither incendiary nor volatile; it has a lower toxicity, is biodegradable, and can be recycled [245]. The emission profile of biodiesel is positive for the environment, and it has superior combustion efficacy, cetane number, flash point, and lubrication than diesel synthesized from petroleum [7,[246][247][248].…”

“…The current global economy is largely dependent on the transportation of goods and services through road, air, and sea routes, thereby exhausting more than 60% of the produced fossil fuel worldwide [4,5]. Biofuels are generally found to be the best replacement for conventional fossil fuel as renewable sources of energy, as a result of their biodegradability, nontoxicity, availability of feedstock, and low emission of poisonous gases [6,7]. Biofuels are purely renewable and therefore considered to be the safest fuel to be used on our planet for the production of goods and services.…”

Performance and emission characteristics of salviniaceae filiculoides aquatic fern oil and SiO2 nano additive biodiesel in CI engine

“…It can help to prevent air pollution by lowering CO 2 , SO 2 , CO, and HC emissions [1]. Because plants absorb more CO 2 than is released by the biodiesel combustion process, the carbon cycle of biodiesel from sustainable resources is a zero budget in terms of photosynthetic process and combustion emission as a whole [2]. When compared to the usage of fossil fuel, biodiesel can more efficiently reduce CO 2 emissions, safeguard the natural environment, and maintain ecological equilibrium [3].…”

Efficient and Stable Rice Husk Bioderived Silica Supported Cu2S-FeS for One Pot Esterification and Transesterification of a Malaysian Palm Fatty Acid Distillate

“…Biodiesel, comprised of long-chain fatty acid methyl esters (FAME), has been drawing considerable interest in recent years as a promising option for diesel derived from petroleum [1][2][3]. Its use has the potential to counter the growing lack of energy fuel and additionally offers a more environmentally friendly and renewable solution to the pollution caused by the utilisation of its petroleum-based equivalent [4][5][6][7]. Esterification is a frequently applied chemical technique for the production of biodiesel from poor quality feedstocks; this reaction is promoted by homogeneous acid catalysts.…”
