Abstract:
The goal of this research is to develop and characterize bio-oil upgrading from pyrolysis Eleocharis Dulcis (ED) using the vacuum distillation process. Bio-oil from slow-pyrolysis Eleocharis Dulcis (ED) was employed as the feedstock. The distillation experiments were performed at temperatures ranging from 96, 97, 98, 99, and 100 C, respectively. After that, the feedstock was distilled to separate the different fuel components. Gas chromatography-mass spectrometer (GC–MS) analysis was used to properly quantify
a typical bio-oil component. The findings indicate that a common critical point was widely present during the distillation process, which may be attributed to a stable system generated by hydrogen bonding. The result showed that Acetic acid, propanone, and phenol were dominant with the concentration ranges of 20–50%, 12–20%, and 13–39.6%, respectively. The extensive distillation characteristics and product distribution contribute to a deeper understanding of the reaction process and component enrichment patterns, which helps with design and parameter optimization.
