AI Technical Summary
Existing multi-step catalytic conversion processes are difficult to maintain stability when catalyst performance changes, resulting in unstable conversion rates and selectivity, and the modulation cascade process increases production costs.
A continuous, unmodulated multi-catalytic conversion process is adopted. Through predictive control methods and design space methods, the changes in catalyst performance are monitored and adjusted in real time. At least two catalysts are used in the continuous, unmodulated multi-catalytic conversion process, and process parameters such as the absolute and relative amounts of catalytically active substances, feed rate and concentration are adjusted in real time.
This achieves stability in conversion rate and selectivity despite changes in catalyst performance, reduces production costs, and improves the economic efficiency of the process.
