项目摘要
Award AbstractProposal Number: CTS-0553439Principal Investigator: Brezinsky, KennethInstitution: University of Illinois - ChicagoProposal Title: Biologically Derived Diesel Fuels and NO Formation As a consequence of the need to reduce nitric oxide, NO, pollutant emissions from the diesel engine combustion of biologically derived fuels, a number of shock tube studies will be undertaken to determine the source of the nitric oxide. The experimental work of determining which different chemical species are formed from different biodiesel fuel components will be combined with a computational approach to address the primary goal of the proposed study understanding the source of higher NO production from biologically derived diesel fuels containing double bonds (unsaturated fuels). The result will be a predictive model of NO formation clarifying the difference between saturated (no double bonds) and unsaturated biodiesel components. The potential technical benefit of this work is the selection of additives or symbiotic biodiesel fuel components for reduction of the pollutant, NO. However the much broader societal and educational impacts of the research will be on the facilitation of the use of indigenous biodiesel fuel sources for enhanced national security and energy independence and on the education of undergraduate, graduate students and post doctoral associates of diverse backgrounds since the UIC shock tube facility has already successfully and significantly aided the academic development and experimental/computational training in the cross cutting field of combustion science of many previous students. It is the primary objective of this proposed work to determine through the use of our high pressure, high temperature single pulse shock tube what is the chemical source of higher NO in double bonded molecular constituents of biodiesel fuels, the intellectual merit of this work, and potentially reduce the formation of NO through the increased understanding and modeling. Accordingly the following activities are planned and contribute directly to the intellectual merit of the proposed work: 1) Oxidation and pyrolysis of the representative, commercially available long chain biodiesel constituents methyl octanoate and methyl octenoate in the UIC high pressure single pulse shock tube with stable species measurements as a function of temperature, 1100-1800K, representative diesel engine pressures, 15-100 bar, and equivalence ratios, 0.5 - 4 and . 2) Detailed chemical kinetic modeling of species concentration versus temperature profiles and high pressure for methyl octanoate and methyl octenoate. 3) Integration of detailed chemical kinetic model for methyl octanoate and methyl octenoate with a predictive NO model that discriminates between NO consequences of saturated and unsaturated fatty acid side chains.
奖项摘要建议编号:CTS-0553439首席研究员:布雷津斯基,肯尼迪研究所:伊利诺伊大学芝加哥分校建议标题:生物衍生柴油和NO的形成由于需要减少柴油机燃烧产生的一氧化氮、NO、污染物排放的生物衍生燃料,将进行一些激波管研究以确定一氧化氮的来源。确定不同生物柴油组分形成哪些不同化学物种的实验工作将与计算方法相结合,以解决拟议研究的主要目标,即了解含有双键的生物衍生柴油(不饱和燃料)产生更高NO的来源。结果将是一个NO形成的预测模型,澄清饱和(无双键)和不饱和生物柴油成分之间的差异。这项工作的潜在技术好处是选择添加剂或共生生物柴油燃料成分来减少污染物NO。然而,这项研究的更广泛的社会和教育影响将是促进本土生物柴油燃料来源的使用,以加强国家安全和能源独立,以及对不同背景的本科生、研究生和博士后助理的教育,因为UIC激波管设施已经成功和显著地帮助了许多以前的学生在燃烧科学交叉领域的学术发展和实验/计算培训。这项拟议工作的主要目标是通过使用我们的高压、高温单脉冲激波管来确定生物柴油双键分子组成中较高NO的化学来源是什么,这项工作的智力价值,并通过增加了解和建模来潜在地减少NO的形成。因此,计划开展以下活动,并直接促进拟议工作的智力价值:1)在UIC高压单脉冲激波管中氧化和裂解具有代表性的、可用于商业的长链生物柴油组分辛酸甲酯和辛烯酸甲酯,并测量随着温度的变化而稳定的组分,1100-1800K,典型柴油发动机压力,15-100bar,当量比0.5-4和。2)对辛酸甲酯和辛烯酸甲酯的物种浓度随温度和高压的变化规律进行了详细的化学动力学模拟。3)将辛酸甲酯和辛烯酸甲酯的详细化学动力学模型与区分饱和和不饱和脂肪酸侧链无后果的预测性NO模型相结合。
