What factors affect CO conversion catalysts?
Thread Content
In the CO conversion process, what factors affect the temperature of the high-activity catalyst (high to low), and how should this be addressed? ? What other factors can affect the high content of variable CO, and what are the reasons for this~~! ? I’m a beginner, so the post might not be very good; I hope everyone can forgive me! !
1. High temperatures affect the catalyst’s activity at low temperatures, thereby reducing its lifespan; low temperatures result in a decrease in conversion rates and lead to substandard process gas. 2. Temperature, space velocity, and water vapor ratio
Are you using high-temperature conversion? Isn’t it common these days to use full low conversion or medium-low-low conversion?
When the manufacturing process is different, there are still some differences in the operations; please explain your process to everyone first.
1\ What factors affect the temperature of highly variable catalysts (high to low) and how should it be handled~~? ? If methanation occurs or water gets introduced, the solution is to introduce medium-pressure steam or reduce the amount of water that enters. 2\ What other factors can affect the high level of CO in the output, and what are the reasons for this? ? Temperature\Pressure\Activity
Main factors affecting CO conversion catalysts: 1. The CO content in the feed gas； 2. Oxygen content in the feed gas ； 3. Toxic substances in the feed gas, especially sulfides ； 4. Amount of water vapor added ； 5. Other reasons such as steam carrying water and gases carrying oil.
The most important factor is temperature~~~ Secondly, the concentrations at the inlet and outlet also have some impact~~~
The main factor is temperature, followed by the sulfur compound content.
Oxygen and water vapor ratios in the process gas, side reactions such as methanation, and probably the load as well. 【Solution: Generally, once the cause is known, addressing it accordingly will do.】 High water vapor ratio, load (space velocity), and high inlet CO content.
We use a medium-low-low transformation
Factors affecting the temperature of highly variable catalysts: 1. Water vapor ratio. 2. Air volume. 3. Catalyst activity. 4. The contents of CO and O2 in the gas. 5. Space velocity of raw coal gas. Factors affecting the CO content in the export gas: 1. Space velocity. 2. The hotspot temperature of the highly variable catalyst. 3. Catalyst activity. 4. Water vapor ratio. 5. Gas drift, short circuit. There are many reasons, and each case should be analyzed on its own merits.
