Abstract：To address issues such as equipment corrosion and wastewater generation caused by sulfuric acid catalysts in the phenol-acetone production process, a modified acidic resin catalyst CTP-20 suitable for cumene hydroperoxide (CHP) decomposition was developed. Using CTP-20 as the catalyst and CHP (mass fraction 50%) as the raw material, the influence of reaction temperature, feed space velocity, and recycle ratio (mass ratio of recycle stream to fresh feed) on the acid decomposition of cumene hydroperoxide was investigated in a fixed-bed reactor. The results showed that at a reaction temperature of 50-60 ℃, CHP space velocity of 2.0-3.0 h-1, and recycle ratio of 5-15, the catalyst exhibited excellent performance, with phenol and acetone selectivity both exceeding 99%. The stability and regeneration experiments of the catalyst showed that the resin catalyst has high selectivity, excellent stability and regeneration performance, indicating good industrial application prospects.
