what is cracking
the
breaking
down of
large
hydrocarbons
into
smaller
more
useful
hydrocarbons
why is there a large demand for smaller hydrocarbons
they're more
useful
as
fuels
than
large
hydrocarbons
because they're more
flammable
Describe two reasons why cracking is useful
it can produce
smaller
alkanes that are in
high
demand as
fuels
it can produce
alkenes
that are used as
feedstock
e.g making
polymers
what is steam cracking
involves
mixing
a
hydrocarbon
with
steam
and
heating
the
mixture
what is catalytic cracking
involves
heating
a
hydrocarbon
in the presence of a
catalyst
what two types of hydrocarbons are produced by cracking
alkanes
alkenes
