DO-20 series precious metal deoxidizer
The DO series deoxygenation catalysts are mainly used for hydrogen deoxygenation, inert gas hydrogenation deoxygenation, synthesis gas, coal gas, coking dry gas deoxygenation, and other aspects. Hydrogen containing deoxygenation and inert gas hydrogenation deoxygenation can be started at room temperature, at (3-10) × 10 ³ Under the condition of h-1 airspeed, the residual oxygen content is less than 0.1ppm (the lowest can reach 0.01ppm). The deoxygenation of syngas, coal gas, and coking dry gas must be carried out at 80 ℃, pressure>0.1Mpa, (3-5) x 10 ³ Under h-1 airspeed conditions, the residual oxygen content is less than 0.1ppm.
Density (g/ml) | Size （mm） | Active components | Particle strength (N） | Heat resistant temperature（℃） | Deoxygenation depth | service life |
0.70±0.02 | Ф3~4 or Ф4~5 | Pd/Pt | ≥70(Ф~3) | 650~700 | <1ppm（the minimum can reach 0.01ppm） | generally ≥ 4 years |
According to different working conditions and gas composition, our deoxygenation catalyst products are divided into five types: A, B, C, D, and E. The difference between different types of catalysts lies in the content of precious metals, different additives, and different carrier modifications. The specific selection is based on process design conditions, cost nucleic acid, energy consumption nucleic acid, etc. All models of deoxygenation catalysts have residual oxygen levels less than 0.1ppm.
