Final-stage nickel catalyst platform converting residual CO and CO2 into methane — protecting ammonia synthesis catalyst and producing methane-rich SNG/CNG/LNG.
Sinotech's methanation catalyst platform supports final-stage gas purification, converting residual CO and CO2 into methane to protect downstream ammonia synthesis catalyst and to produce methane-rich SNG, CNG or LNG streams. Catalyst selection is reviewed against feed gas composition, operating space velocity, pressure and the required outlet CO+CO2 specification.
Titanium-rare-earth nickel methanation catalyst removing residual CO/CO2 from hydrogen-rich gas, with SMN-310A rated for high-pressure, high-space-velocity duty.
Nickel methanation catalyst converting CO/CO2-rich coke oven gas and methanol purge gas into SNG, CNG or LNG across a wide pressure and space-velocity range.
High-nickel methanation catalyst built for coal-to-SNG service, combining low-temperature start-up activity with high-temperature stability and anti-coking performance.
| Area | Technical Control Focus | Industrial Relevance |
|---|---|---|
| Activity & Selectivity | CO/CO2 conversion at target space velocity | Determines outlet gas purity and downstream catalyst protection |
| Pressure / Velocity Tolerance | High-pressure, high-space-velocity duty rating | Supports double-methanol and SNG unit throughput |
| Strength & Loading | Crush strength, abrasion resistance | Supports reactor loading and bed life |
| Anti-Coking Performance | Carbon-deposition resistance | Extends service life under wide load swings |
Each model in the family, set out by process duty, application and role. Full technical datasheets are available on request.
SMN-310 and SMN-310A are titanium-rare-earth nickel methanation catalysts that strip low concentrations of CO and CO2 from hydrogen-rich feed gas. High strength, high pore volume and high activity make loading and unloading straightforward, while SMN-310A is tuned for the higher pressure and higher space velocity found in double-methanol unit methanation sections.
SMN-330 and SMN-340 convert coke oven gas, methanol plant purge gas and other gases rich in CO, CO2 and H2 into SNG, CNG or LNG. The pair delivers strong low-temperature activity, high-temperature resistance and anti-coking performance across a wide span of operating space velocity and pressure.
Sinotech's SNG methanation catalyst is a high-nickel system developed specifically for coal-to-SNG service. It combines low-temperature start-up activity with high-temperature resistance, high CO/CO2 conversion, abrasion resistance, anti-carbon-deposition behavior and anti-poisoning performance for long service life.
