| Regeneration Cycle | 4-7 months |
| Catalyst Lifetime | 4-6 years |
2. When the content of acetylene reaches 1.0-1.9%, two-stage hydrogenation promoted by the acetylene hydrogenation catalyst will do well.
First Reactor

| H2 to Acetylene Ratio (v/v) | 1.0-1.4:1 |
| Acetylene Conversion Rate | 40-90% |
| Outlet Acetylene | 0.15-0.45% |
| Ethylene Plus | 0.00-0.50% |
| Regeneration Cycle | Min. 3-6 months |
| Catalyst Service Life | 2-5 years |
Second Reactor
| Pressure | 1.0-4.0Mpa |
| Inlet Acetylene | 0.10-0.45 % |

3. When the content of acetylene is lower than 0.6 (V %), one-stage hydrogenation with the help of the acetylene hydrogenation catalyst is sufficient.
| Pressure | 1.0-4.0Mpa |
| Inlet Acetylene | 0.10-0.45 % |
| Inlet Temperature | 45-90℃ |
| Space Velocity | 2000-8000h-1 |
| H2 to Acetylene Ratio(v/v) | 1.2-2.6:1 |
