Over the years’ research of benzene process maleic anhydride catalyst and fumaric acid catalyst, Changzhou NEW SOLAR Catalysts Co., Ltd. has reached a world-top level in terms of benzene process maleic anhydride catalyst. On this basis, we developed the NSMA-BSL-2-FA1 catalyst—Fumaric Acid Dedicated Catalyst in the second half of 2015, which is similar to the benzene process maleic anhydride catalyst featured with high activity and light acid water color.
The catalyst has the following characteristics:
Appearance and size: 7.5*4.5mm hollow ring type
Bulk density: 1.00±0.05kg/ L
Crushing strength: greater than 100N
Abscission rate of active component: less than 1.0%
Number of filling layers: 2 layers
Single tube operating load: 100-130g/h, can be adjusted according to the operating conditions of the device
Single pipe operating air volume: 2800-3500g/h (2.2-2.7nm3 /h), can be adjusted according to the operating conditions of the device
Acid yield: 108-110%
Conversion rate: greater than 99%
Initial salt temperature: 350℃
Service life: normal 3 years
Nsm-bsl-2-fa1 fumaric acid catalyst, in the pilot test evaluation data has shown that although its oxidation yield performance is lower than our company's high yield benzene maleic anhydride catalyst, but is 1-1.5 percentage points higher than other domestic catalysts, to achieve low salt temperature, high activity, long life, stable performance, at the same time, This type of fumaric acid catalyst has a more preferential price.
At the end of 2015, the company launched the market sales of fumaric acid special catalyst products, and we welcome the intended users to visit the company and negotiate at any time. We hope to contribute to the development of fumaric acid industry through our efforts!
