✔ Cobalt-Molybdenum (Co-Mo) on Alumina – Used for low-sulfur feeds.✔ Nickel-Molybdenum (Ni-Mo) on Alumina – More active, used for high-sulfur feeds.

Ensures Safety: PTWs help manage and control the hazards associated with high-risk work. They are essential for protecting workers and ensuring a safe working environment. Regulatory Compliance: Many industries require PTWs to comply with local regulations, standards, and safety laws. Prevents Accidents: ...

Signs include high reactor pressure drop, decreased conversion efficiency, and higher reactor temperatures. Mitigation involves increasing hydrogen-to-feed ratio, periodic catalyst replacement, and using guard beds.

Follow Emergency Shutdown Procedures (ESD): 1️⃣ Stop the feed pump. 2️⃣ Close reactor inlet valves. 3️⃣ Maintain nitrogen purging. 4️⃣ Monitor hydrogen venting to prevent pressure buildup.
