Abstract

BACKGROUND

The purification of crude glycerol, a byproduct of biodiesel production and grease trap waste, is essential for its utilization in high-value applications. Achieving exceptionally pure glycerol without relying on energy-intensive vacuum distillation during transesterification is of substantial economic interest.

RESULTS

This investigation focuses on crafting a purification process involving chemical treatment (neutralization), adsorption and extraction. The assessment of the neutralization process using sodium hydroxide (NaOH) and potassium hydroxide (KOH) revealed their comparative efficacy. Activated carbon adsorption was used to reduce coloration in crude glycerol, with weights set at 4 and 8 wt%. Efficient salt extraction from crude glycerol was explored using solvents such as methanol, ethanol and isopropyl alcohol in varying mass ratios to crude glycerol (1:1 and 2:1). The study also examined the synergistic effects and impact of mixing alcohol solvents. Optimal conditions for achieving high purity (92.44%) were identified as the combination of KOH, 8 wt% activated carbon and a 2:1 ratio of a mixture of the three alcohols.

CONCLUSION

The combined effects of employing a mixture of alcohols significantly enhance the extraction process, resulting in the efficient and successful purification of glycerol. These outcomes offer valuable insights into improving the extraction process in industrial settings, leading to the production of high-quality glycerol products. © 2024 Society of Chemical Industry (SCI).

从隔油池废弃物生物柴油生产中优化粗甘油提纯:探索混合提取醇对提高甘油纯度的协同效应
背景生物柴油生产过程中产生的副产品粗甘油和隔油池废物对其在高价值应用领域的利用至关重要。在酯交换过程中,无需依赖高能耗的真空蒸馏即可获得纯度极高的甘油,这具有重大的经济意义。使用氢氧化钠(NaOH)和氢氧化钾(KOH)对中和过程进行的评估显示了它们的功效。活性炭吸附用于减少粗甘油中的色素沉淀,吸附重量设定为 4 和 8 wt%。研究使用甲醇、乙醇和异丙醇等溶剂,以不同的质量比(1:1 和 2:1)从粗甘油中高效提取盐分。研究还考察了混合醇类溶剂的协同效应和影响。结果表明,将 KOH、8 wt% 的活性炭和 2:1 比例的三种醇的混合物结合在一起,可获得高纯度(92.44%)的最佳条件。这些结果为改进工业环境中的萃取工艺,从而生产出高质量的甘油产品提供了宝贵的启示。© 2024 化学工业协会 (SCI)。
