Characteristics of dry and wet sulfurization of catalysts
Thread Content
Wet sulfidation of catalysts generally uses normal paraffinic low-nitrogen oils; the advantage is that it facilitates wetting of the catalyst for sulfidation, and it helps to remove the heat of reaction, thus making it easier to control the temperature of the bed. The disadvantages include increased energy consumption, pollution from sulfided oil, and loss of some sulfiding agents. The reaction temperature in dry vulcanization is difficult to control, but it can save vulcanized oil. Who else knows their characteristics? Hope to discuss it
Wet vulcanization provides a favorable environment for heat and mass transfer, making the vulcanization process more stable and enabling better vulcanization results to be achieved.
