3.3.2 ALKANES SPONTANEOUS COMBUSTION

Non polar as electronegativity between H and C is similar

Increases as the strength and quantity of van der waal forces increases

Same logic as unsaturated fatty acids

Cant dissolve in water as its non polar

mixture of mostly branched and linear alkanes and impurities

1)Crude oil is heated in a furnace to make vapour.
2)The vapour passes into the column.
3)Columns temperature decreases as you go up
4)Vapours goes up the tower until reaching a tray cooler than their boiling pt
5)Vapour condenses and is collected and piped off

Good -Gasses
People - petrol
Kick - kerosene
Delusional -diesel
Lorries - lubricating oil
For - fuel oil
Banter - bitumen

shorter alkanes
alkenes - chemical feedstock / raw material

High temperatures of 700 -1200 K and up to 7000kPa
C-C bond breaks in a way initially forming free radicals
Produces high proportions of alkenes

Lower temps of 720K and pressures around 101kPa but uses honeycomb zeolite with huge SA
Produces branched alkanes( good for petrol) cycloalkanes and aromatic compounds

CO + H20 OR
C + H20

CO2 AND H20 - Greenhouse gases
CO - toxic and flammable
C - respiratory issues and global dimming
Unburnt hydrocarbons - smog and greenhouse gases
SO2 + NO - respiratory issues and acid rain

More efficient and cheaper

its in the exhaust system coated with honeycomb shaped platinum/ rhodium etc
Converts CO +NO to CO2 +N2
Hydrocarbons to CO2 + H20

CaO + H20 is sprayed over flue gas(contains SO2) which forms gypsum
CaSO4.H20
CaCO3 can also be used
