Application and characteristics of methanation catalyst:

1.1 Application:

The co2 methanation catalyst is mainly used for large, medium and small types of fertilizer plant synthesis ammonia industry, mainly in the synthesis gas of a small amount of carbon monoxide, carbon dioxide under the action of the methanation catalyst and hydrogen reaction to produce water and inert methane, in order to protect the ammonia synthesis catalyst and prevent the system crystallization blockage. Methanation catalyst can also be used in the organic hydrogenation industry to purify high purity hydrogen devices.

1.2 XYJ105 methanation catalyst reaction and characteristics:

The methanation catalyst takes high quality electrolytic nickel as raw material and uses a unique process to add lanthanum oxide rare earth as accelerator. Methanation catalyst has the characteristics of good low temperature activity, strong thermal stability, wide reaction temperature range, not easy to heat aging, high mechanical strength, not easy to pulverize and long service life. Its quality exceeds the level of similar products in the world.

Methanation is a strong exothermic reaction, the reaction formula is as follows:

CO+3H₂ = CH₄+HO₂ △H⁰₂₉₈= -206.2KJ/mol

CO2+4H₂ = CH₄+2HO₂ △H0298 =-165.0KJ/mol

Main physicochemical indexes of XYJ105 high-pressure methanation catalyst:

2.1 Physical properties:

2.2 Chemical composition:

3. Catalyst quality standards:

The main performance characteristics of XYJ105 methane catalyst:

1. Good heat resistance activity:

XYJ105 methanation catalyst with nickel as the active component, and high nickel content, while using a unique process, adding rare earth elements as accelerators, with high activity and thermal stability, the quality of thismethanation catalyst has exceeded the level of similar domestic products.

2. High compressive strength:

According to the actual use of the customer, J105 methanation catalyst has the characteristics of high strength, not easy to powder, long service life, etc. The strength of the methanation catalyst before reduction is generally above 180N/cm, and the strength after reduction can be increased by about 20%.

3. Good toxicity resistance:

After a large number of experiments and actual use results show that methanation catalyst is very sensitive to sulfur, chlorine, arsenic and other toxicity, a short time of toxic substances exceeding the standard can make the methanation catalyst poisoning and cause a significant decline in catalyst activity, and J105 methanation catalyst has auxiliary protection, so the toxicity resistance is better.

4. Good thermal stability performance:

The results of many methanation catalyst manufacturers show that J105 methanation catalyst has strong thermal stability, and the methanation catalyst is still active after many overtemperature accidents (the most serious temperature exceeds 600℃ for nearly 3 hours).

5. Reaction characteristics of catalyst:

In the actual production process, the methanation catalyst reaction is gas-solid reaction, and the activity of the catalyst itself is very high, the reaction process is strong exothermic, irreversible diffusion control process, and the reaction speed is fast.

Use precautions of XYJ105 methanation catalyst:

● Temperature: Usually the initial use of the methanation catalyst performance is good, the inlet temperature can be adjusted in the operating temperature of 240 ~ 260℃, the bed temperature is maintained at 290 ~ 320℃, and the reaction temperature can be appropriately increased with the extension of the use time to ensure that the outlet is qualified.

● Prevent overtemperature: Methanation furnace overtemperature is mostly caused by the abnormal decarbonization system, a large number of CO₂ into the methanation furnace caused by, if the synthesis of nitrogen is added before the methanation furnace, the oxygen content of nitrogen can exceed 0.05%, whether it is O2, CO, CO₂ caused by temperature rise of more than 500℃, will cause different degrees of sintering inactivation of the methanation catalyst, the formation of nickel aluminate spinel, In particular, the overtemperature caused by O2 and the temperature gradient of the active center of the particles is larger, and the sintering damage at the same temperature is more serious. O2 exceeding the temperature faster, once found, immediately cut off the nitrogen source, to be analyzed after qualified, must be the gas in the pipeline after a period of time before it can be added to the furnace.

● Prevent low temperature gas conduction: When the gas temperature into the methanation furnace is below 200℃ or the bed heat storage temperature is below 200℃, the CO in the gas will form nickel carbonyl with the active component nickel in the methanation catalyst, the reaction formula is as follows:

Ni+4CO = Ni (CO)₄ (gas)

This reaction is easiest to carry out at about 150℃, and the generated nickel carbonyl gas is lost with the migration of the air flow, and nickel carbonyl is extremely toxic to the human body.
