摘要
在金属卟啉催化氧化环己烷模试研究的基础上,将金属卟啉催化氧化技术直接应用于70 kt/a环己酮无催化氧化工业生产装置,考察环己烷转化率和产物的选择性。结果表明:在现有的工业装置上,直接使用金属卟啉催化剂,环己烷的转化率达5％-6％,选择性为93.9％-95.3％(以摩尔计),均高于无催化氧化工艺,环己烷消耗比无催化氧化工艺降低76 kg／t。在相同转化率下,工业试验的氧化选择性也高于模试研究。
Based on the study of simulated experiment, the technology of cyclohexane catalytic oxidation with metal porphyrin was applied in a 70 kt/a cyclohexanone non-catalyst oxidation plant. The relationship between cyclohexane conversion and selectivity was studied. The results showed that metal porphyrin catalyst applied in an existed plant yielded cyclohexane conversion 5%-6% and selectivity 93.9%-95.3% after capacity enhancement, both of which were higher than non-catalyst oxidation. The cyclohexane consumption was decreased by 76 kg/t, as compared with non-catalyst oxidation. The industrial experiment had higher oxidation selectivity than the simulated experiment.
