Other sources of olefinic hydrocarbons

Finally, as shown by Table 128. these light cuts themselves contain significant concentrations of oiefmic hydrocarbons. Moreover, they are the only effluents of catalytic cracking that the refiner may agree to make available for petrochemicals. 

On the whole, process performance, namely the product distribution, varies according to the operating conditions (space velocity, pressure, temperature, catalyst circulation
