Don't ignite easily

Don't ignite easily

Have high boiling points

Have high boiling points

Have low volatility

Have low volatility

Test yourself on Heavy Fractions of Crude Oil

  • The reasons why heavy fractions of crude oil don't make good fuels

  • Good fuels need to ignite easily, have low boiling points and high volatility. Which type of crude oil fraction fails to meet these requirements?

  • Why don't heavy fractions of crude oil make good fuels?

  • Heavy fractions of crude oil have high boiling points, which stops them from being good fuels. What type of boiling point does a good fuel need?

  • Would heavy fractions of crude oil work well as fuel in a car engine, which needs quick ignition and easy vaporising?
