In Fischer-Tropsch process for production of hydrocabons from CO and `H_(2),` the catalyst used is………..

Explanation

**Step-by-Step Solution:**

1. **Understanding the Fischer-Tropsch Process**: The Fischer-Tropsch process is a chemical reaction that converts carbon monoxide (CO) and hydrogen gas (H₂) into liquid hydrocarbons. This process is significant in producing synthetic fuels.

2. **Identifying the Catalyst**: In the Fischer-Tropsch synthesis, specific catalysts are used to facilitate the reaction between CO and H₂. The most commonly used catalysts are iron (Fe) and cobalt (Co).

3. **Conclusion**: Therefore, the catalysts used in the Fischer-Tropsch process for the production of hydrocarbons from CO and H₂ are iron and cobalt.
