Industrial experiment of cyclohexane oxidation catalyzed by metal porphyrin

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.
