I. Working principle:T6SMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
T6SMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
The catalyst roasting furnace removes organic matter, moisture and other impurities in the catalyst through high-temperature heating, thereby improving the activity and stability of the catalyst. During the roasting process, the catalyst needs to be heated in a specific atmosphere (such as air, nitrogen or reducing atmosphere), and the temperature is usually between 400℃ and 700℃. In this process, impurities such as organic matter and moisture on the surface of the catalyst are oxidized or decomposed into gas and volatile substances, and desorbed and removed from the surface of the catalyst. At the same time, the roasting process can also promote the crystal growth and pore structure formation inside the catalyst.T6SMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
