How to regenerate activated carbon used as a desulfurization catalyst
Thread Content
To improve the desulfurization efficiency of the desulfurization catalyst, it is possible to carry out simple regeneration during shutdowns – how should this be done? Can the manhole be opened to come into contact with air? ； Or steam is introduced from the bottom ； What are the advantages and disadvantages of each? Are there any other methods? Please speak up actively to promote a low-carbon economy and energy conservation in our country.
The best method is back-purging, which involves using a tank to fill it with nitrogen and then carrying out the purging in the reverse direction of the normal process. The goal is to blow away the adsorbed sulfur compounds so as to facilitate regeneration.
