As the feed gas like Natural gas, Naphthas always contain several hundred parts per million of more complex organic sulfur compounds and may be pre-treated in a hydrofiner before use in ammonia or hydrogen production. Variation in the sulfur content of feed does not affect the performance of the hydrodesulfurization catalysts and absorbents although larger volumes of absorbent must be included in the plant design to achieve a convenient operating cycle before replacement.
Chempack offers several types of the NiMo/CoMo Hydrodesulfurization Catalyst for organic sulfur conversion with differenct shapes like Spheres, Cylinders, Trilobe, Quadralobe and Hollow Rings for low pressure drop consideration.
