Catalyst loading ratio
Thread Content
What is the catalyst loading ratio for each section of the five-stage converter?
Based on empirical data, the figures are as follows: First section: 18-19%, Second section: 18-19%, Third section: 20-21%, Fourth section: 20-21%, Fifth section: 22-23%. These are merely empirical values; in practice, considerations such as the selected model and design parameters must be taken into account
It has to be determined based on the designed flue gas SO2 concentration, loading factor, etc.
Hehe, it depends on the operating conditions to determine the requirements; you can ask Monsanto and Topsoe for quotes and proposals, and they will take care of it for you
Answer: The distribution ratio of each stage in the five-stage conversion process varies from manufacturer to manufacturer, and it differs as well between imported and domestic catalysts; even among imported catalysts, there are those that contain cesium and those that do not. Therefore, the specific loading ratio needs to be determined for you by the catalyst manufacturer. 1# ha498671385
The proposal from the catalyst manufacturer is provided for reference; please review the relevant materials on your own to finalize it
The catalyst amount used in the fifth conversion stage is smaller, but a cesium-added catalyst is required; the presence of cesium facilitates heat transfer and temperature rise, enabling the catalyst in this stage to reach its catalytic temperature more quickly and resulting in more complete conversion； Additionally, it is recommended that the third paragraph also use a cesium-containing catalyst, with the same function as that in paragraph five
