齐翔腾达自主研发顺酐催化剂

Group 1 - The core achievement of Qihang Tengda is the development of a domestic catalyst for the oxidation of n-butane to produce succinic anhydride, which won the first prize for technological progress at the Shandong Energy Group's third technology conference [1] - The company started its research on the catalyst in 2016 to reduce reliance on expensive and limited foreign catalysts, which required long lead times for orders and could disrupt production and product quality [1] - The research team conducted extensive small-scale tests and later scaled up the catalyst trials, achieving excellent performance in activity, selectivity, and stability [1] Group 2 - The catalyst development team did not stop at laboratory success but worked closely with operational staff to optimize various parameters under different load and temperature conditions, resulting in a 5% reduction in catalyst consumption [2] - The performance of the new catalyst surpassed that of imported catalysts, with key technical and economic indicators improved by 2%, effectively breaking the domestic reliance on imported catalysts for the n-butane oxidation process [2] - The project has established a 720 tons/year industrial production facility, with the catalyst being successfully applied in Qihang Tengda's 400,000 tons/year succinic anhydride plant and also used by surrounding chemical enterprises, saving approximately 9.6 million yuan in raw material costs annually [2]
