Comparison of transformation catalyst sulfidation blower and circulation compressor
Thread Content
Dear sea friends, when it comes to the vulcanization of catalysts, which is better to use: a vulcanization blower or a circulation compressor? What are the issues and precautions associated with each during operation?

During cyclic sulfidation, the transformation catalyst does not require very high pressure; a pressure of 0.3–0.35 Mpa is generally sufficient. The key is to maintain a stable air velocity, that is, to ensure a constant amount of hydrogen sulfide being supplied; only in this way can the bed temperature of the conversion catalyst be effectively controlled. Use nitrogen to maintain stable pressure at the inlet of the circulation fan ； The addition of hydrogen must be controlled at a certain ratio in accordance with the requirements of the catalyst manufacturer ； The amount of vulcanizing agent should be added gradually in accordance with the requirements of the catalyst manufacturer.
Sulfurization fans are used, featuring low pressure and high flow rate. When operating, pay attention to adjusting the opening degrees of the inlet and outlet valves; otherwise, fan surge may occur. We use a sulfur-resistant low-temperature shift catalyst, and sulfurization is carried out using a solid sulfurizing agent via a cyclic sulfurization method.
