Question

$CO+H_2\underset{CoorNi}{\overset{43K,1.1\text{atmosphere}}{\to }}$ mixture of hydrocarbons $+H_{2}O$ The above reaction is :

• A. Bergius process
• B. Fischer-Tropsch process
• C. Kolbe's process
• D. none of the above

Answer 1

Answer: (B)

This process is for the synthesis of synthetic petrol and is known as Fischer-Tropsch process
$\underset{\text{ Red coke Steam }}{C+H_{2}O}⟶\underset{\text{Water gas }}{\underbrace{CO+H_2}}$
$\underset{\text{excess }}{\underbrace{CO+H_2}}\underset{\underset{Co/Ni\text{catalysis}}{1-10atm}}{\overset{473K}{\to }}$ Mixture of hydrocarbons $+H_{2}O$
Bergius process is also used for manufacture of synthetic petrol
$C+H_2\underset{\underset{750K}{200-250atm}}{\overset{\text{Iron oxide}}{\to }}$ Mixture of hydrocarbons
Kolbe's process is used for manufacture of hydrocarbons.
