Modification of alkanes by cracking Flashcards
1
Q
What is cracking?
A
The process of converting alkanes into alkenes and shorter alkanes.
2
Q
Explain thermal cracking
A
Thermal cracking takes place at high pressure and high temperature and produces a high percentage of alkenes
3
Q
Explain catalytic cracking.
A
Catalytic cracking takes place at a slight pressure, high temperature and in the presence of a zeolite catalyst and is used mainly to produce motor fuels and aromatic hydrocarbons and shorter alkanes
