I’m a beginner and I’ve never understood the role of filling the purification furnace with antidotes in the isothermal transformation process
Prevent poisoning and deactivation of the conversion catalyst
Remove toxic substances such as mercury and arsenic present in raw gas
Remove substances in raw gas that are harmful to the shift catalyst, such as oxygen, mercury and arsenic, dust, etc., to extend the lifespan of the shift catalyst.
What is the mechanism by which antidotes work to counteract toxins, and how do they achieve this effect?
