Question

Identify the catalyst used in synthesis of gasoline by Fischer Tropsch process.

• A. Platinized asbestos
• B. Fe-Cr
• C. Co-Th
• D. \(\text{MnO}_2\)

Hint:

Fischer-Tropsch uses a cobalt-thoria catalyst on CO and H2.

Answer 1

The Correct Option is C

Step 1: Recall:
Fischer-Tropsch converts CO and $\text{H}_2$ into alkanes (gasoline range) using a cobalt-based catalyst promoted with thoria.

Step 2: Match each catalyst with its process:
Platinised asbestos: contact process. Fe-Cr: water gas shift. Co-Th: Fischer-Tropsch. $\text{MnO}_2$: decomposition of $\text{KClO}_3$.

Step 3: Choose:
Co-Th is for the synthesis of gasoline.

Final Answer:
The catalyst is Co-Th, option (C). \[ \boxed{\text{Co-Th (C)}} \]
