Is it possible to use activated carbon to remove oil and refine desulfurization from coke oven gas?
Thread Content
As the title suggests, are the companies that produce methanol from coke oven gas currently carrying out oil removal and advanced desulfurization of the carbon? If it’s useful, what are the advantages and disadvantages of activated carbon and iron-based desulfurizers respectively, and which one is better? Welcome everyone to discuss; thank you!
Both are used to remove trace amounts of sulfur; the height-to-diameter ratio for desulfurization must be greater than 3. For gases with high sulfur content, it is recommended to use other methods for preliminary desulfurization first. Iron-based desulfurization catalysts are inexpensive, have a low sulfur capacity, tend to release sulfur once saturated, require frequent replacement, and require more filling volume compared to activated carbon. For activated carbon desulfurization, the humidity in the gas should be above 70%; it is preferable to have trace amounts of oxygen or ammonia present. The sulfur capacity of coal-based materials should be between 15-20%, while that of wooden materials should be above 20%. For precise desulfurization, activated carbon is recommended.
Both of these are useful; they are suitable for applications where high precision in output is not required. The sulfur capacity of activated carbon should be lower than that of iron-based materials. Only high-quality activated carbon can achieve a sulfur capacity on par with that of iron-based materials, though its price may be higher.
Hello, friend. Isn’t the sulfur capacity low in iron-based materials? Are you from a coking plant? Let’s chat on WeChat; my WeChat ID is 13589508010
Iron oxide desulfurization is irreversible, while activated carbon can be regenerated for reuse; however, neither is recommended for the final desulfurization step. Zinc oxide is the best choice, as it enables an outlet purity level of <0.1 ppm.
Thank you for participating! During the initial rough purification step, a lot of activated carbon is used, right? Or rather, after wet rough purification and before moving on to the dry process, activated carbon is used for purification in order to extend the lifespan of zinc oxide? Add WeChat: 13589508010
No, I work for a company that produces catalysts. Do you need these?
