Patent ID: 7423189

Claim:
A method of utilizing a catalytic reaction to recycle organic scrap, comprising the following steps: placing an organic scrap and a catalyst into a vertical cracking furnace to crack said organic scrap into a primary cracked gas and a solid product at a reaction temperature higher than 220° C., said catalyst including 55˜62% silica (SiO 2 ), 4˜7% potassium oxide (K 2 O), 0.5˜35% sodium oxide (NaO), 2˜2.5% ferric oxide (Fe 2 O 3 ), 0.2˜1% titanium oxide (TiO 2 ), 27˜35% alumina (Al 2 O 3 ), 0.2˜1% magnesia (MgO), and 0.5˜1.5% calcium oxide (CaO); and collecting said primary cracked gas from the top of said vertical cracking furnace, and feeding said solid product into a rotary cracking furnace, which is installed below said vertical cracking furnace, to crack said solid product into a secondary cracked gas and a cracked oil at a reaction temperature raging from 365 to 390° C.
