1. the method for transformation of a Petroleum, it is characterised in that at least comprise the following steps:

  • A) charging containing Petroleum is passed through the first reaction zone, 580 DEG C~

    the reaction temperature of 700 DEG CDown with the catalyst haptoreaction containing molecular sieve, product is isolated to stream I and product I;

    B) gained stream I in water vapour and step a) is passed through second reaction zone, at 780 DEG C~

    870 DEG CReaction temperature under carry out steam pyrolysis reaction, obtain product I II after reaction;

    Described stream I includes the alkane that carbon number is 2~

    5;

    Described product I include aromatic hydrocarbons that alkene that carbon number is 2~

    12, carbon number are 6~

    12 andCarbon number is the alkane of 6~

    12;

    Described product I II includes the virtue that low-carbon alkene that carbon number is 2~

    4, carbon number are 6~

    8Hydrocarbon.
