Homework Help: Crude Oil

  1. Mar 7, 2008 #1
    1. I have a relatively simple question, but I cant think of the answer.
    A high bp hydrocarbon (X) is obtained by the fractional distillation of crude oil. (X) is then heated in the presence of silicate materials. only 3 new hydrocarbons were from this proces.

    All I want to know is what is this process called?

    We thought maybe a combustion but somehow we dont think thats right coz no co2 is prodced.

    Any help would be awesome thanks!!!!

    this is called cracking. it is usually done with the naphta fraction. the large alkane molecules break down into smaller alkanes and alkenes molecules and even hydrogen.
