摘要

通过乙醇-乙酸发酵将短链羧酸链延伸为中链羧酸,生产生物基平台化学品可以为循环经济做出贡献。为了避免进一步的浪费,可以使用已经含有短链羧酸的二次废物。本文研究了从塑料废物回收厂的二次废物中生产生物基羧酸的潜力。因此,以塑料废物回收厂的工艺水进行了实际试验,以评估生产羧酸的潜力。实验结束时,二次废弃物中伸长链得到的丁酸浓度为496 mg/L,己酸浓度为87 mg/L,萃取溶剂中己酸浓度为933 mg/L。综上所述,二次废物中羧酸的链延伸通常是可能的,在本例中是来自塑料废物处理厂的工艺水。为了估计生产的总潜力,必须考虑工艺水质量的波动。

Analysis of secondary waste from a plastics recycling plant for the production of carboxylic acids
The production of bio-based platform chemicals through the chain elongation of short-chain carboxylic acids to medium-chain carboxylic acids by ethanol-acetat fermentation can be a contribution to the circular economy. To avoid further waste, secondary waste that already contains short-chain carboxylic acids can be used. The potential for the production of bio-based carboxylic acids from a secondary waste of a recycling plant for plastic waste is examined in this paper. Therefore, practical experiments with the process water of a recycling plant for plastic waste were conducted in order to assess the potential for carboxylic acids production. At the end of the experiment, the concentrations achieved by chain elongation in the secondary waste result in 496 mg/L butyric acid and 87 mg/L caproic acid and the concentration in the extraction solvent is 933 mg/L caproic acid. To conclude, chain elongation of carboxylic acids in secondary waste, in this case the process water from a treatment plant for plastic waste, is generally possible. In order to estimate the total potential for the production, the fluctuations of the quality of the process water have to be considered.
