Cinnamol sulfate color development

2025-03-24View Original

Thread Content

For the vapor-phase hydrogenation unit for octenal, the catalyst used in the reactor is a conventional copper-based catalyst; there are two types of such catalysts – one type is used for producing n-butanol and the other for producing octanol. The catalyst is in its mid-to-late stage of service. Suddenly, the sulfuric acid coloration test results became excessively high. Please help me analyze what other factors might be contributing to this phenomenon, aside from a decrease in catalyst activity (the composition of the products after hydrogenation remained unchanged)
