B303Q is a patented product of the national brand, exclusively produced. Industrial application began in 1988, and in 1990, it was appraised by the Ministry of Chemical Industry. The appraisal and naming opinions suggest that:; This catalyst has the characteristics of good low-temperature activity, wide temperature range for use, strong antioxidant properties, and high conversion rate of organic sulfur. Good mechanical strength, does not pulverize when in contact with water, and its product quality is at the leading level in China;.
Detailed Introduction
B303Q is a patented product of the national brand, exclusively produced. Industrial application began in 1988, and in 1990, it was appraised by the Ministry of Chemical Industry. The appraisal and naming opinions suggest that:; This catalyst has the characteristics of good low-temperature activity, wide temperature range for use, strong antioxidant properties, and high conversion rate of organic sulfur. Good mechanical strength, does not pulverize when in contact with water, and its product quality is at the leading level in China;.
This product is currently the only product in China that has passed the industrial application appraisal of the full low-temperature transformation process, and is also the only sulfur resistant transformation catalyst recommended by the China Nitrogen Fertilizer Industry Association. It has been successfully applied in the medium to low, medium to low, and full low-temperature transformation processes of more than 1000 (secondary) large, medium, and small nitrogen fertilizer plants.
