Product Description

 

Echnical field: acrylonitrile catalyst, is adapted to propane, propylene, liquid ammonia as raw materials, under the action of the catalyst can produce acrylonitrile chemical products, this acrylonitrile (an) catalyst, is a dual-purpose new, efficient, environmentally friendly catalyst.

The catalyst is composed of metal molybdates such as iron, nickel, and magnesium, loaded on a silica carrier, and is a small particle with an average particle size of 50um.

Acrylonitrile catalysts are widely used in the production of synthetic fibers resins rubber etc

     The GR-XYA5 catalyst used in acrylonitrile plant is a catalyst with molybdenum and bismuth as the main active components, and the element molybdenum is easily sublimed and lost in the reaction process. With the increase of catalyst use time, the activity of the catalyst decreases, the acrylonitrile yield decreases, and the propylene and ammonia consumption of the device increases, which is the characteristic that the acrylonitrile industry is different from other industries.
      Acrylonitrile (AN) is a material monomer used in the synthesis of acrylic fiber, and is an important chemical raw material, which is widely used in the fields of polyacrylonitrile fiber, rubber, plastic and so on. In the production of acrylonitrile, the use of catalysts can improve the reaction rate and selectivity and promote the synthesis of acrylonitrile.
       As long as there is no large technical input (such as updating the catalyst), the acrylonitrile per reactor catalyst will decrease year by year, and the unit propylene and ammonia consumption of the plant will increase year by year. At the end of catalyst use, the catalyst activity (propylene conversion) decreased, the catalyst single yield to acrylonitrile decreased, and the impurities produced in the reactor increased.

2 Catalyst filling capacity :440g;
3 Raw material ratio (propylene + ammonia + air): volume fraction (1+1.2+9.5):
4 Raw material purity: propylene reference GB/T 7716;
5 Ammonia (liquid): Mass fraction ≥99.8%:
6 Reaction pressure: 0.08MPa;
7 Reaction temperature :440ºC;
8 propylene airspeed :WWH=0.08;
9 Catalyst particle size requirements:
105~88μm 5% 30g
88~44μm 70% 420g
≤44 μm 25% 150g
A total of 600g was taken according to the above screening requirements, and 440g was weighed into the reactor.

Operation procedure:
1 When the system is open to air, turn on the reactor electric heating to heat up.
2 When the temperature of the reaction section reaches 380ºC, ammonia is put in, and then propylene is put in.
3 Adjust propylene, ammonia, air flow to the calibration value.
4 When driving normally, the outlet maintains the calibrated reaction pressure, and the temperature rises to the specified reaction temperature and runs stably.

 

Application

 

Application of the latest supplementary catalyst:

In February 2013, the 130,000-ton/year plant used SANC-08 catalyst.
In April 2021, the new supplementary catalyst was added, and the single revenue was 79% in the first three months of the addition, and the acrylonitrile yield reached 80.5~81%, and the acrylonitrile yield was increased by more than 1 percentage point. At present, the catalyst has been running for the 11th year, and the catalyst performance is stable and the additive effect is remarkable.
The average yield of acrylonitrile in 2023 will be 81.2%
