cracking of hydrocarbons Flashcards
1
Q
what are the conditions required to crack hydrocarbons
A
high temperatures between 450c to 750c
pressure up to 70 atmospheres
to break large hydrocarbons into smaller ones.
2
Q
how does cracking work
A
large hydrocarbons are broken down by thermal decomposition into higher demand alkanes and alkenes.
3
Q
why is the shorter chain alkane useful in cracking
A
the shorter chain alkanes are more valuable because they are fuel
4
Q
why is the alkene useful when cracked
A
because the alkene can be used to make polymers to manufacture plastics
5
Q
why is cracking important
A
because it can make 2 different useful products like fuel and polymer and it can be used in different industries
