Abstract

The influence of the 0.4 T magnetic field on catalytic cracking of the vacuum gasoil and its mixture with 5% cottonseed oil was evaluated. Magnetic field intensity excites aromatic resins existing in the vacuum gasoil and causes more effective cracking. Catalytic cracking was conducted using commercial X-zeolite fluid catalytic cracking catalyst and reaction products, especially gasoline and diesel fractions were analyzed in detail. Magnetic field increased the yield of the diesel fraction from 7 to 33% and enriched its composition with aromatic hydrocarbons while opposite effect was observed in gasoline. Cracking mechanisms in formation of gasoline and diesel range hydrocarbons were briefly discussed.
