Answer :
The hazards of carbon deposit include the blocking of micropores, influence heat transfer, and increasing the bed resistance. More than half of natural gas in China is utilized to make nitrogen fertilizer, and ammonia synthesis catalyst is a-Fe. In the ammonia synthesis process, the main method of separating ammonia is the condensation method.
The carbon deposit, which is one of the hazards, can accumulate in the catalyst bed, resulting in the blocking of micropores, which can decrease the catalyst's efficiency. Carbon deposition on the catalyst surface can also lead to a decrease in the catalyst's activity and life span. It can also cause the bed to be more resistant to the flow of gases.14. More than half of natural gas in China is utilized to produce nitrogen fertilizer. Nitrogen fertilizer, which is mainly made of ammonia, is a vital component in increasing crop yields and the quality of produce.15. The catalyst used in ammonia synthesis is α-Fe (alpha-iron). Iron-based catalysts, such as α-Fe, have a high catalytic activity for ammonia synthesis, which is why they are utilized.
They are also less expensive and easier to produce than other catalysts.16. The condensation process is the primary method for separating ammonia in the ammonia synthesis process. Cooling the gas mixture below the ammonia's boiling point condenses the ammonia. This process is effective in separating ammonia from other gases such as hydrogen and nitrogen. The separation process is then complete, and the ammonia can be further processed for use or storage.
