Propylene consumption:Compared with the data of competitors in the same period, propylene consumption is more than 10kg/tan, which has a clear leading advantage in the world.
• Catalyst stability: the catalyst on the Anqing I-C unit has been running for nearly 10 years, and the Anqing II-C unit has been running for nearly 11 years
And the application is still continuing, indicating the excellent stability of the catalyst.
• Catalyst cleaning performance: The device has been running continuously for more than 1000 days, and the catalyst has good cleaning performance.
| Product Description |
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 catalyst a new type of catalyst high efficiency and environmental protection
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 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.
With its own technology, self-production and self-marketing.

Test of sample
Preparation of test solution
1) The catalyst was added to the reactor, and after stable operation for 2 hours under specified conditions, one bottle of 0.1mol/L hydrochloric acid and two bottles of distilled water were used as the absorption solution to absorb the reaction products. The sampling time of each bottle of 300mL of absorption solution was 15 minutes, and the sampling time was four consecutive times.
2) The absorption solution in the absorption bottle was moved to the 2000mL volumetric bottle, the absorption bottle was cleaned three times with water, the cleaning solution was poured into the volumetric bottle, diluted with distilled water to the scale, and connected with the outlet of the reactor to absorb part of the reaction product as a liquid sample for the analysis of hydrocyanic acid and acrylonitrile, acetonitrile, acrylein, and acrylic acid according to (2) and (3).
3) The gas sampler is used to collect the exhaust gas of the reactor, and the gas collected in the gas sampler must be replaced for more than 3 times during sampling. The collected gas is used to analyze carbon monoxide, carbon dioxide, propylene, propane, etc., separated by Porapak Q column and 13X column chromatography, detected by thermal conductivity detector, and quantized by external standard method.
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.
