After a lot of tests in laboratory and industrial project application, we prove that the following methanation catalysts are high efficiency, long lifetime, high temperature resistant and stable. These methanation catalysts also make coal chemical process rational and efficient.
1. Catalyst for coke oven gas methanation to produce natural gas
Coke oven gas methanation to produce natural gas is a high effective way of using clean energy. This catalyst is specially designed for methanation of coke oven gas, and has advantages of high strength, high temperature resistance, and good stability. It also has high activity and selectivity.
The working principle is:
CO + 3H2 → CH4 + H2O,CO + H2O → CO2 + H2
2. Coal gas methanation catalyst
The catalyst is used to produce high fever value gas or gasoline alternative fuel, i.e. compressed natural gas from coal syngas by using high temperature and high pressure methanation technology. It’s an important clean way of using coal. With the increase of liquid energy prices, this technology has received more and more attention.
The catalyst has high catalytic activity, high thermal stability and operation velocity.
Its working principle is:
CO + 3H2 → CH4 + H2O,CO + H2O → CO2 + H2
3. Catalyst for production of city gas from water gas methanation
The product is an innovative catalyst with non-uniform methanation activity. It has merits of high activity, anti caking, anti fly temperature and dual methanation transform functions.
When using this catalyst, coal gas need no pre transformation. Combining with corresponding techniques, the use of this catalyst forms a complete set of methanation technology for city gas production.
This invention is patented and was awarded many times for its technology progress.
Its working principle is:
CO + 3H2 → CH4 + H2O,CO + H2O → CO2 + H2
4. Carbon dioxide deep methanation catalyst
Using coal gas methanation technology to produce high heat gas or gasoline alternative fuel compressed natural gas is an important clean way of using coal. With the increase of liquid energy prices, this technology has received more and more attention.
This product applicable to end process of methanation of the total coal gas decarbonize and methanation process, and has high catalytic activity and high CO and CO2 conversion rate. After removing H2O, the product is so called artificial natural gas.
Its working principle is:
CO + 3H2 → CH4 + H2O,CO + H2O → CO2 + H2
5. Sulfur tolerant methanation catalyst
This catalyst has been patented, and is used for methanation of coal gas containing sulfur. It has merits of high conversion rate, high selectivity and good stability.
Its working principle is:
CO + 3H2 → CH4 + H2O,CO + H2O → CO2 + H2
