The main features of the desulfurizer are three highs and one low: high desulfurization precision, high penetration sulfur capacity, high strength and low price. The use of this type of desulfurizer can save the hydrogenation unit, shorten the process and reduce the cost.

Chemical composition of desulfurizer: The main raw material is manganese, iron, zinc and copper carbonate. Add a low-temperature high-activity co-catalyst and shape it by extrusion. Appearance color and dimensions: gray-black, Φ3~4×4~15 mm strips. Desulfurizer strength: lateral crushing strength ≥ 60 N/cm; wear resistance ≥ 98%. Bulk density: 1.15~1.25 kg/liter.

Conditions of use of desulfurizer: pressure: 0.1-4.0MPa(G); space velocity: 100-2000h-1; temperature: 150-450℃, suitable temperature: 150-400℃. Desulfurization accuracy: 0.1×10-6; breakthrough sulfur capacity: 20-22% (Wt); working sulfur capacity: 24-26% (Wt).
