Reasons for the low content of conjugated dienes in cracked C5 and countermeasures

This post was last edited by crocodile1981 on 2023-8-11 at 17:44. Recently, the concentration of conjugated dienes in our pyrolyzed C5 has dropped to around 37%, which does not meet the customer’s requirements. I would like to ask the experts for possible reasons and how to make adjustments

Possible causes and countermeasures are as follows: 1. Unstable raw material quality: The raw materials contain impurities or exhibit significant quality fluctuations. The countermeasures are to regularly test the quality of raw materials, select suppliers who provide materials of stable quality, and work together with those suppliers to address any quality issues. 2. Catalyst deactivation: The catalyst may become deactivated due to prolonged use or contamination. The countermeasure is to replace the catalyst regularly and enhance its protection and maintenance. 3. Improper control of reaction conditions: Conditions such as the temperature, pressure, and feed liquid ratio in the pyrolysis reaction may not be properly controlled. The countermeasure is to optimize the reaction conditions by adjusting parameters such as temperature, pressure, and feed liquid ratio in order to increase the yield of the product. 4. Reactor equipment issues: The reactor equipment may suffer from problems such as aging, wear, or clogging, resulting in poor reaction efficiency. The countermeasure is to regularly inspect and maintain the reactor equipment to ensure it is in good working condition. 5. Inadequate skill of operators: The operators may not have a sufficient understanding of the pyrolysis reaction or the necessary technical expertise. The countermeasure is to strengthen the training and technical guidance for operators, in order to improve their operational skills and theoretical knowledge. The above are the reasons that may lead to a decrease in the concentration of conjugated dienes in cracked C5, along with the corresponding corrective measures. It is necessary to determine based on the actual circumstances which aspects need to be adjusted. It is recommended that you take appropriate measures to solve the problem by considering the on-site conditions as well as the advice of professionals. .

Thank you for the answer, but I still have a few questions. First, what kind of catalyst is meant by catalyst contamination? Second, what does insufficient operational skill refer to?
