1
Q
Order the fractions of crude oil
A
Natural gas, petrol, naphtha, kerosene, diesel, lubricating oil, fuel oil, bitumen
2
Q
Thermal cracking conditions
A
1200K 7000kPa
3
Q
Catalytic cracking conditions
A
720K zeolite catalyst and normal pressure
4
Q
Contrast catalytic and Thermal cracking.
A
Higher pressure and temp for thermal.
Catalytic produces aromatic compounds.
5
Q
Sulfur atmosphere equation
A
SO² + H²O + ½O² –> H²SO⁴
6
Q
Flue gas desulfurisation equation
A
CaO³ + 2H²O + So² + ½O² –> CaSO⁴.H²O
7

Initiation step for chlorination of alkanes
A
Cl² –> 2Cl•
8
Q
Propagation steps for chlorination of alkanes
A
Cl• + CH⁴ -> •CH³ + HCl
•CH³ + Cl -> CH³Cl + Cl•
9
Q
Termination step for chlorination of alkanes
A
•CH³ + •CH³ -> C²H⁶
Cl• + Cl• -> Cl²
