1. , a kind of technology of production support of the catalyst is characterized in that, this technology is consisting essentially of following operation:

  • A) solution of organometallic compound in inert organic solvents of the 2nd or 13 families in the life cycle table, heat of immersion activation silicon-dioxide;

    B) use polar solvent to prepare the solution of one or more magnesio compounds;

    C) use operation b) silicon-dioxide that a) obtains of the solution impregnation operation of preparation;

    D) remove polar solvent by vacuumizing;

    E) with operation d) solid that obtains, react with the solution of one or more organometallic compounds in inert organic solvents of periodictable the 2nd or 13 families.
