125. What is Hydrogenation or Hydro finishing reac

121. What are the properties of Aromatics?

  • They are not very reactive in spite of the presence of double bonds.
  • They behave more like saturated compounds.
  • Excellent anti-knock properties.
  • Used as commercial solvents due to their high solvent power.
  • Poor VI components.
  • Produces smoky flames

122. What is cracking?

Heavier hydro carbons are cracked or broken into smaller molecules to produce more valuable lighter products from the low priced heavier hydrocarbons.

123. What is Alkylation?

It is the process of combing two dissimilar hydrocarbons. A catalyst is used in this reaction of saturated compounds with unsaturated.

124. What is Polymerization?

Similar to Alkylation, except that in this case two un saturates are combined over a catalyst.

125. What is Hydrogenation or Hydro finishing reaction?

In this reaction hydrogen combines with unsaturated hydrocarbon make them a saturated compound over a catalyst.
