摘要

为了获得一种纯可再生的第二代生物燃料,研究了红花油和甜菜糖蜜乙醇的酯交换反应,以及作为混合组分的使用选择。化石燃料的消耗、化石燃料价格的上涨以及与化石燃料有关的排放都是重大的全球性问题。纯生物基和更安全的燃料的发展对解决这些问题具有重要意义。生物柴油是一种很好的替代传统柴油的候选燃料。主要以脂肪酸甲酯为原料生产。然而,由于环境和技术问题,乙基酯虽然具有许多优点,但仍未得到重视。因此,使用源自生物乙醇的副产品作为酒精和红花油作为不可食用的原料,将进一步提高第二代生物燃料之一的可再生性和可持续性。研究了红花油与甜菜糖蜜源生物乙醇的酯交换反应。考察了红花油与乙醇(摩尔:摩尔)比、催化剂用量和温度对酯含量的影响。按照标准测定了红花油乙酯和2%、5%、7% v/v红花油乙酯混合柴油和农村柴油的燃料性能。在柴油中添加乙酯的主要优点是闪点提高,硫含量降低。然而,一些添加剂应改善某些性能(冷滤堵塞点和氧化稳定性)。

FATTY ACID ETHYL ESTERS OBTAINED FROM SAFFLOWER OIL: A FULLY RENEWABLE BIOFUEL
With the aim to obtain a pure renewable second-generation biofuel, transesterification reaction of safflower oil and sugar-beet molasses originated ethanol, and usage options as a blend component were investigated. Depleting fossil fuels, increasing fossil fuel prices, and fossil fuel-related emissions are significant global problems. The progress in pure biobased and safer fuels gains importance to figure out these problems. Biodiesel is an excellent fuel candidate that can substitute conventional diesel fuel. For its production, fatty acid methyl esters were primarily proposed. However, with their many advantages, ethyl esters have come to the fore because of environmental and technical issues. Thus, using a by-product originated bioethanol as alcohol and safflower oil as a non-edible raw material would further enhance the renewability and sustainability of one of the second-generation biofuels. This paper studied the transesterification reaction of safflower oil with sugar-beet molasses originated bioethanol. The effects of the safflower oil:ethanol (mole:mole) ratio, catalyst amount, and temperature on the ester content were individually investigated. The fuel properties of safflower oil ethyl ester and 2%, 5%, 7% v/v safflower oil ethyl ester blended diesel and rural diesel fuels were determined according to the standards. The main advantages of ethyl ester addition to diesel fuel include the increase in flash point and the decrease in sulfur content. However, some additives should improve some properties (cold filter plugging point and oxidation stability).
