Technical Positioning

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.

Model Details

Each model in the family, set out by process duty, application and role. Full technical datasheets are available on request.

SMN-310 / SMN-310A

Standard Methanation Catalyst

Process Duty
Final-stage methanation
Application
Hydrogen-rich gas purification; SMN-310A for double-methanol units

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 / SMN-340

Coke Oven Gas Methanation

Process Duty
Methanation for SNG/CNG/LNG production
Application
Coke oven gas, methanol-plant purge gas and other CO/CO2/H2-rich streams

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.

SNG methanation catalyst

Coal-to-SNG Methanation

Process Duty
Coal-to-SNG methanation
Application
Coal-to-substitute-natural-gas systems

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.

How Selection Works

Methanation catalyst selection is reviewed against:

Feed gas source (synthesis gas / coke oven gas / purge gas) Inlet CO+CO2 concentration Required outlet CO+CO2 specification Operating temperature Operating pressure Space velocity Particle form (sphere/cylinder) Anti-coking requirement Service-life target Pilot/customer trial feedback
