C1: Carbon Chemistry
- C1a: Making Crude Oil
Useful
- Fossil fuels are finite reasources
and are non renewable
- Finite reasources are no longer
being made or being made
extremely slowly
- Non renewable
reasources are being
used up faster than they
are being made
- Finite reasources are no longer
being made or being made
extremely slowly
- Crude oil is a mixture of
hydrocarbons
- All the readily extractable reasources
will be used up in the future
- Finding Replacements
- Conflict between
petrochemicals and
fuels
- All the readily extractable reasources
will be used up in the future
- Environmental problems
involved in the transport
of crude oils
- Damage to Bird
feathers causing death
- Use of detergents to clean up
oil spills and consequent
damage to wild life
- Damage to Bird
feathers causing death
- Political problems
associated with crude oil
- UK dependant on oil and gas from
politically unstable countries
- Future supply issues
- UK dependant on oil and gas from
politically unstable countries
- Cracking -
help match
supply to
demand
- Fractional Disstillation
- 1. Crude oil is heated
- 2. Use of fractioning column which
has a temperature gradient
- 3. Fractions containing mixtures of
hydrocarbons obtained
- 4. fractions contain many substances
with similar boiling points
- 5. Fractions with low boiling points exit
form the top, high boiling points leave from
the bottom
- 5. Fractions with low boiling points exit
form the top, high boiling points leave from
the bottom
- 4. fractions contain many substances
with similar boiling points
- 3. Fractions containing mixtures of
hydrocarbons obtained
- 2. Use of fractioning column which
has a temperature gradient
- 1. Crude oil is heated
- In a hydrocarbon
molecule there are:
- Strong
covalent
bonds
between
atoms
- Weak
intermolecular
forces
- Strong
covalent
bonds
between
atoms
- Intermolecular forces
between longer
hydrocarbons are stronger
than shorter
- Intermolecular forces
can break but covalent
bonds don't
- Cracking is a process
that converts large
alkane molecules into
smaller alkene and
alkane molecules
- Makes
useful
alkene
molecules
into
polymers
- Fossil fuels are finite reasources
and are non renewable
