提出了一种通过匹配实际燃料的官能基团来构建生物柴油替代燃料的方法。选取MD5D、正十二烷和1,4-己二烯作为基础燃料,以燃料的重要化学官能基团、H/C比、O/C比和(CH_2)/(CH_3)×[GH_2+CH_3]值等为匹配目标得到各基础燃料的配比,并结合各基础燃料的既有机理构建了生物柴油的替代燃料机理。将获得的替代燃料机理用于理想搅拌反应器燃烧和零维均质着火过程的模拟,模拟结果与实验数据的对比表明,该替代燃料机理能较好地预测生物柴油在不同压力、温度和当量比下的氧化过程和着火特性。本文所提出的生物柴油替代燃料机理构建方法具有一定的通用性,为替代燃料机理的构建提供了新的思路。
A method of constructing alternative biodiesel fuels by matching the functional groups of the actual fuels is proposed. MD5D, n-dodecane and 1,4-hexadiene were selected as the basic fuels. The chemical functional groups, H / C ratio, O / C ratio and (CH_2) / (CH_3) × [GH_2 + CH_3 ] Values for the matching target to get the ratio of the base fuel, combined with the existing mechanisms of the base fuel to build an alternative fuel mechanism of biodiesel. The obtained alternative fuel mechanism was used to simulate the ideal stirred reactor combustion and the zero-dimensional homogeneous ignition process. Comparing the simulation results with the experimental data, the alternative fuel mechanism can better predict the biodiesel under different pressures, temperatures and equivalents The oxidation process and ignition characteristics. The proposed biodiesel alternative fuel mechanism construction method has a certain versatility, which provides a new idea for the construction of alternative fuel mechanism.
