Stainless steel high-pressure reactors are essential for hydrogenation, offering, durable, corrosion-resistant environments (often SS316) for exothermic reactions at high pressures (up to 5000+ psi) and temperatures. These reactors, frequently used with catalysts (e.g., Ni, Pd), feature strong agitation to ensure hydrogen-liquid contact and crucial cooling systems to manage heat and safety.
