Our company uses designs developed by the Second Chemical Research Institute: iron-molybdenum catalysts for the first stage of hydrogenation and nickel-molybdenum catalysts for the second stage. Without shutting down production, carbon disulfide is used for catalyst sulfidization, but carbon disulfide is extremely dangerous. Gentle experts, does anyone know of better vulcanization methods or materials?
Appearance: Slightly yellow transparent liquid. Test parameters and specifications: Content % (m/m) ≥ 99; Density (20°C) g/cm³ 1.061–1.066; Moisture % (m/m) ≤ 0.1; H2S, CH3SH content % (m/m) ≤ 0.05; Freezing point: ≤ –20°C; Flash point: ≥ 16°C; Viscosity (20°C): mm²/s 0.60–0.64.
