Research on Oxidation of Jixi Lignite by Alkali Oxygen |
| |
| Abstract: | Jixi lignite was oxidized by alkali oxygen in water solution of NaOH under temperature range of 180—240℃. Observed was the influence on yield of aromatic carboxylic acid by parameters as alkali/lignite ratio, reaction temperature, initial oxygen pressure, reaction time and water quantity. Experiment results denoted that main effective factors on acid yield were alkali/lignite ratio and initial oxygen pressure. |
