How is the service life of a catalyst calculated?
Thread Content
The company exam included a calculation problem: given the catalyst loading in tons, the processing capacity in tons per hour, and the operation time in days, determine the service life of the catalyst
Reply to 2# yjl19830062: It should be Processing volume/Loading volume = Lifespan, right?
The lifespan of a catalyst is influenced by various factors, and it cannot be simply calculated based on parameters such as the processing volume and loading amount. The people who create such questions in the company basically don’t understand the particularities of chemical catalysis processes. The lifespan of some catalysts is extremely long; for example, the platinum mesh used in the oxidation of ammonia to nitric acid has an almost infinite lifespan ； The lifespan of catalytic cracking catalysts is much shorter. Additionally, the catalyst is also affected by impurities in the raw materials, operating conditions, and changes in surface properties. If the catalyst life can be calculated using a simple formula, then what’s the point of conducting catalyst life tests and other evaluations of catalyst performance?
