Catalyst technology for the production of acrolein and acrylic acid
Product overview
The proven industrial technology for the catalytic synthesis of acrolein and acrylic acid has been successfully implemented in numerous installations and is protected by a number of patents. The accumulated scientific and technical reserve amounts to more than 300 significant achievements in the field of research and development.
For large-scale acrylic acid production, it is critical to maintain stable catalyst activity in a high-temperature oxidizing environment while ensuring high selectivity for the conversion of acrolein to acrylic acid, suppressing side reactions and maximizing feedstock efficiency.
Key technical aspects:
• Long-term balance of catalyst activity and selectivity;
• Optimization of the temperature profile in the reaction layer to prevent local overheating and catalyst deactivation;
• Structural stability under conditions of continuous operation with high load;
• Control of product purity and impurity content.
The use of mature technology for the catalytic oxidation of acrolein into acrylic acid can significantly increase the efficiency of the installation, reduce specific energy consumption and provide a stable raw material base for the production of superabsorbent polymers (SAP), environmentally friendly coatings, adhesives and other high-tech materials.
