摘要

摘要牛奶生产过程中产生的乳制品渣滓是生产生物柴油的潜在来源。它是一种密度较低的漂浮固体物质,主要由甘油三酯和脂肪酸组成,它们是燃料的重要成分。本研究旨在使用NaOH/KOH催化剂,通过酯交换工艺,利用乳制品废料浮渣生产生物柴油。本工作使用低成本的方法在两种碱性催化剂NaOH和KOH之间确定了更好的催化剂。初步确认的特征,如密度、热值、运动粘度、比重、闪点和燃点,将支持通过所提出的方法形成合成生物柴油。实验结果表明,在温度为55°C、反应时间为120 min,催化剂负载量为1 最后,在CI发动机中测试生物柴油的排放和燃烧特性。为了优化工艺参数,使用MINITAB19进行了响应面法(RSM)和Bootstrap估计。此外,还报道了从方差分析中获得的实验和预测产量。

Dairy waste scum as a potential feedstock for bio-diesel production: optimisation, quality and reliability studies
ABSTRACT Dairy waste scum obtained from the downstream milk production process is a potential source to produce biodiesel. It’s a less dense floating solid mass that primarily consists of triglycerides and fatty acids, which are important constituents for fuel. The present study aims to produce biodiesel using dairy waste scum by a transesterification process using NaOH/KOH catalysts. The present work identifies the better catalyst between two alkaline catalysts NaOH and KOH, using low-cost methodologies. The preliminary confirmation characteristics, such as density, calorific value, Kinematic Viscosity, Specific Gravity, Flash Point, and Fire Point will support the formation of synthesised biodiesel via the proposed methodology. The experimental results lead to a yield of 89.02% of biodiesel using NaOH catalyst with optimised process parameters of the temperature of 55°C, the reaction time of 120 min, and catalyst loading of 1 wt./wt.%. Finally, biodiesel was tested for emission and combustion characteristics in a CI engine. To optimise the process parameters, the response surface methodology (RSM) along with Bootstrap estimation has been performed using MINITAB19. Furthermore, the experimental and predicted yields obtained from ANOVA were reported.
