Question

$ CO+H_{2}\xrightarrow[Co\,or\,Ni]{43\,K,\,1.1\, \text{atmosphere}} $ 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 } \longrightarrow \underbrace{ CO + H _{2}}_{\text {Water gas }} $
$\underbrace{ CO + H _{2}}_{\text {excess }} \xrightarrow[\underset{Co/Ni\, \text{catalysis}}{1 - 10 atm}]{473\,K}$ Mixture of hydrocarbons $+ H _{2} O $
Bergius process is also used for manufacture of synthetic petrol
$C + H _{2} \xrightarrow[\underset{750 \,K }{200 - 250\,atm}]{\text{Iron oxide}}$ Mixture of hydrocarbons
Kolbe's process is used for manufacture of hydrocarbons.
