The component of recycled plastic and cracking principle:

Recycled plastic which is formed by polymerization with alkene in oil as a raw material is a solid macromolecular material.And it's called polyolefin,molecular number is about 10 thousand or so;The principle is that it adopts the catalytic pyrolysis method under the high temperature condition to make macromolecular polyolefin break into small molecules of which C5H12~C11H24 etc is components of gas and C12H26~C20H42 etc is components of diesel.Oil refining can get different densities by different temperature period of gas and diesel.20% of these cracking liquid is similar with gas component and it can reach the standard of 90-93 gas after adjustment;80% is similar with diesel component and it can reach the requirement of 0,-10,-20 diesel after adjustment.And they can be as industrial and civil gasoline and diesel,even as power oil.The major chemical reactions are as follows:

                                          Catalyst

     (-CH3-CH2-)n +(-CH3-CH2-)                                                 360°

n(C+CH4+C2H6+C3H8+……+C11H24+C12H26+……+C20H42+C22H46)

Among them, C5H12~C11H24 are gasoline fractions,

             C12H26~C20H42 are diesel distillates.
