MHT CET Chemistry Question (2026) — Solution

Question

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

Options

  1. A. Platinized asbestos
  2. B. Fe-Cr
  3. C. Co-Th
  4. D. MnO _2

Answer

C. Co-Th

Step-by-step solution

The Fischer-Tropsch process is a collection of chemical reactions that converts a mixture of carbon monoxide and hydrogen (syngas) into liquid hydrocarbons, such as gasoline. The reaction requires a catalyst to proceed efficiently. The most common and historically significant catalysts used for this synthesis are based on transition metals like cobalt, iron, or ruthenium. Specifically, a mixture of cobalt and thorium oxide (Co-Th) supported on kieselguhr is a classic and widely used catalyst in the Fischer-Tropsch synthesis of gasoline. Answer: Co-Th
