  2. Crude oil The Big Question How can we make crude oil useful? Lesson Objective - understand that crude oil is a mixture of hydrocarbons. - describe and explain how the industrial process of fractional distillation separates crude oil into fractions. - recall the names and uses of the main fractions obtained from crude oil: refinery gases, gasoline, kerosene, diesel, fuel oil and bitumen. - describe the trend in boiling point, volatility and viscosity of the main fractions. - understand that fractional distillation of crude oil produces more long-chain -hydrocarbons than can be used directly and fewer short-chain hydrocarbons than required.

  3. Brainstorm all the words and phrases that come to mind when you think of the word crude.

  4. video 3 levels of worksheet to choose from to complete when watching the video. Might want to watch video twice – especially for highest level Level 1 – Word fill with word bank Level 2 – Word fill without word bank Level 3 – No word fill – student just has to write their own explanation of fractional distillation – key words given

  6. Note Writing • Crude oil vaporizes and passes in to fractionating Columns. • The different fractions condense and come out the tower at different heights according to there boiling point. • The fractions with small molecules having lowest boiling points are collected a the top and fractions with large molecules having higher boiling point would be collected at the bottom.

  7. Starter 2 How many of the products made from crude oil can you remember? There was 9 at the start. How many can you list in your books in 30 seconds? End 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30

  8. Exercise Book Questions Name three different types of fuels? Describe methane with its chemical formulae. Define petroleum? Explain how petroleum is separated to useful fractions. Describe the properties of molecules within a fraction. Name the uses of the fractions.

  9. Answers Name three different types of fuels? Coal, natural gas and petroleum. 2. Describe methane with its chemical formulae. The main constituent of natural gas ●methane, CH4 3. Define petroleum? It is a mixture of Hydrocarbons. 4. Explain how petroleum is separated to useful fractions. ● different hydrocarbons have different carbon chain lengths, with longer chain carbon chains having higher boiling points ● their different boiling points means petroleum can be separated by fractional distillation: ○ a large fraction column with petroleum is heated ○ different hydrocarbons boil and rise up as gases, which can then be collected separately .

  10. 5. Describe the properties of molecules within a fraction. ● Some properties of hydrocarbons depend on the size of their molecules. These properties influence their use as fuels. ● The shorter the molecules, the lower the temperature at which that fraction evaporates or condenses – and the lower its boiling point. ● Shorter the molecules, the less viscous it is. (more runny) 6. Name the uses of the fractions. ● Refinery gas for bottled gas for heating and cooking ● Gasoline fraction for fuel (petrol) in cars ● Naphtha fraction for making chemicals ● Kerosene/paraffin fraction for jet fuel ● Diesel oil/gas oil for fuel in diesel engines ● Fuel oil fraction for fuel for ships and home heating systems ● Lubricating fraction for lubricants, waxes and polishes ● Bitumen for making roads.
