What is The Hazard of Carbonation During The Heating Process?

Today, Hydrogen Peroxide Manufacturing Plant, to explain to you the harm of carbonation reaction during the heating process of silver formaldehyde production. And how does it relate to the reaction temperature?

What is the hazard of the carbonation reaction?

During the heating process of silver formaldehyde production, the free carbon particles generated by the carbonation reaction will adhere to the surface of the catalyst particles, so that the active surface area of the catalyst is reduced, and the performance of the catalyst is not effectively exerted, which shows an increase in side reactions and CO2 in the exhaust gas. The CO content is high, and the methanol content in the product is high, resulting in an increase in methanol unit consumption.

Its relationship with reaction temperature

The temperature range of the carbonation reaction is between 530 and 580 °C. Although the activity of the electrolytic silver catalyst increases rapidly between 530 and 580 °C, it still leaves a certain space for the carbonation reaction. Therefore, when the temperature is raised to 530-580 °C, the raw materials and oxygen deficiency required for the carbonation reaction are required. At the same time, high temperature, catalytic activity and low selectivity are also available, and the carbonation reaction is inevitable. The temperature range is “black barrier zone”.
