✔ 最佳答案
1a)It the fractionally distillation of crude oil.
1b)
The main device is the fractionating tower.
2a)
The nickel catalyst provides reactive surface for the reaction.
2b)
Pass the gaseous mixture through sodium hydroxide solution.
2NaOH(aq) + CO2(g) → Na2CO3(aq) + H2O(l)
OR: 2OH-(aq) + CO2(g) → CO32-(aq) + H2O(l)
2c)
CH4(g) + H2O(g) → CO(g) + 3H2(g)
2d)
Nitrogen is obtained by fractional distillation of liquefied air.
