Cracking liquid paraffin. In the horizontal test tube are a piece of mineral wool (brown) soaked in liquid paraffin,and porcelain chips,which act as a catalyst. As the porcelain chips are heated the vapour from the paraffin is 'cracked',or broken down into smaller hydrocarbons. The hydrocarbon gases move along the glass tube and are collected in the test tube at left. Large hydrocarbons,such as crude oil,do not flow well are are difficult to ignite. Cracking them into smaller hydrocarbons makes them easier to use | |
