What are the precautions for loading protective and environmental friendly catalyst

The packaging quality of protective environmental protection catalyst directly affects the bed resistance and airflow distribution, and affects the performance of protective environmental protection catalyst, so the packaging of protective environmental protection catalyst is very important.


1. remove all sundries in the furnace before filling.

2. before loading, determine the loading amount and height of catalyst in each section of the shift furnace, and mark the loading height of catalyst in the furnace.

3. before filling, a layer of fire-resistant balls and wire mesh should be laid on the grate, and then filled with protective environmental protection catalyst.

4. environmental friendly catalysts should be comprehensively inspected before filling. If dust is found, it should be removed through a screen.

5. during refilling, gently pour into the furnace from the lowest possible height. The free falling height of particles is less than 0.5m. The catalyst should be scattered and not poured into a pile to avoid that each part of the bed is very close. Affect the uniform distribution of air flow.

6. During the filling process, operators are strictly forbidden to step on the catalyst to prevent the palladium catalyst from being crushed and make the bed tight. In order to avoid stepping directly on the protective environmental protection catalyst, place a wooden board on the bed and let people operate on it. After each layer of catalyst is installed, scrape it with a wooden board and cover it with a layer of wire mesh and fire-resistant ball.

7. Environmentally friendly catalysts easily absorb moisture in the air. After absorbing water, it will affect the activity and strength of the catalyst. Therefore, it is not advisable to load the catalyst into the furnace too early. Generally, the furnace is installed within one to two days before start-up. After the furnace is installed, the inlet and outlet of the shift furnace shall be sealed to prevent other gases from entering the shift furnace, which will damp the catalyst.

8. When installing protective environmental protection catalyst, operators should wear work clothes and protective articles.
