Four-leaf clover alumina catalyst carrier compared to Other Shapes(such as spherical, cylindrical, trilobe etc),have following advantages:

2. Optimized Hydrodynamic Performance
– The Four-leaf clover ensures more uniform fluid distribution in fixed-bed reactors, minimizing channeling and improving reaction homogeneity.
– Compared to trilobe supports, the Four-leaf clover shape maintains high mechanical strength while further reducing pressure drop, making it suitable for high-flow reactions (e.g., hydroprocessing, reforming).

3. Superior Mechanical Strength
– The symmetrical design of Four-leaf clover supports provides higher crush strength than trilobe or some honeycomb structures, reducing breakage risks during loading or operation.

4. Enhanced Active Metal Loading Capacity
– The grooves and porous structure facilitate highly dispersed deposition of active metals (e.g., Ni, Mo, Co), improving catalytic activity and stability.
– Compared to spherical supports, Four-leaf clover carriers allow higher metal loading while minimizing sintering risks.

5. Broad Applicability in Catalytic Reactions
Four-leaf clover alumina catalyst carrier are widely used in:
– Petroleum refining (hydrotreating, hydrocracking, reforming)
– Chemical catalysis (Fischer-Tropsch synthesis, selective hydrogenation)
– Environmental catalysis (SCR denitrification, VOC abatement)
