Heterogeneous Catalysis

Solid catalyst you can filter off and reuse
🎯 Difficulty ★★★ Advanced Duration About 5–10 h 🎯 Use Use solid catalysts for hydrogenation, oxidation, etc., with easy separation and recycling.
📖 Principle
Reaction occurs on a solid surface; filter it off and reuse the catalyst.

📋 Workflow

Full workflow, products add-to-cart directly
1

Activate the catalyst

1–2 h
Pretreat metal/oxide catalyst at high temperature under reducing/oxidizing gas to activate sites.
💡 Tip Control carrier-gas flow and temperature well
⚠️ Caution H₂ reduction needs good exhaust

2

Charge the reactor

30 min
Load activated catalyst into a fixed-bed or slurry reactor, seal, and leak-check.
💡 Tip Even packing in fixed bed aids flow
⚠️ Caution Poor sealing leaks high-pressure gas

3

Pressurize and react

2–6 h
Introduce feedstock/gas, raise pressure and temperature stepwise, sample for conversion.
💡 Tip Stepwise heating avoids runaway
⚠️ Caution High-pressure exotherms need relief valves

4

Separate and regenerate

1 h
Filter/settle out the catalyst after unloading; regenerate by calcination/reduction as needed.
💡 Tip Regenerate gently to avoid sintering
⚠️ Caution Coked catalyst needs careful regeneration

⚠️ 5 Common Beginner Mistakes

  • Unactivated catalyst underperforms
  • Poor seals leak
  • Rapid heating causes runaway
  • Coking shortens catalyst life
  • Over-regeneration sinters and deactivates

❓ FAQ

+Heterogeneous advantages?
Easy separation/recycle, ideal for continuous processes.
+How many cycles?
Tens of cycles before regeneration depending on decay.
+Detect deactivation?
Conversion drops unrecoverably plus coking/sintering by characterization.
