Question

state why it is difficult to separate ethane and ethene

Answer 1

Explanation:

here's your answer

• The technique would avoid liquefaction and distillation by designing a material that only binds ethylene molecules, thus separating them from ethane. ... However, the chemical reaction used to convert ethane into valuable ethylene is incomplete, so such plants produce an impure mixture of ethylene and ethane.

hope it's helpful for you ☺️

Answer 2

Answer:

In steam cracking, a gaseous or liquid hydrocarbon feed like naphtha, LPG or ethane is diluted with steam and briefly heated in a furnace without the presence of oxygen. Typically, the reaction temperature is very high, at around 850 °C, but the reaction is only allowed to take place very briefly.
