Quality of a diesel is measured in terms of its?

  1. Cetane number

  2. Octane number

  3. Gold number

  4. Avogadro number
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A cetane number is the measure of the quality of the diesel . Higher cetane number indicates that the fuel ignites more readily when sprayed over hot compressed air.

Complete removal of ______ from gasoline is done by Unisol process using caustic soda and methyl alcohol. 

  1. asphalt

  2. mercaptans

  3. diolefins

  4. waxes
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Unisol process is a regenerative method for not only extracting or removing mercaptans but also some of the nitrogen compounds. In this process first gasoline is washed counter-currently with aqueous caustic methanol solution. The spent caustic is regenerated in a stripping tower where the methanol, water and mercaptans are extracted.
