PYROLYSIS OF MIXED PLASTICS IN THE FLUIDIZED BED USING HARD BURNT LIME AS BED MATERIAL
A mixture consisting of 40 wt％ PS, 20 wt％ PE, 20 wt％ PP and 15 wt％ PET were pyrolyzed in the presence of both steam and nitrogen, using a fluidized bed reactor with hard burnt lime (HBL) as bed material. The experiments were carried out at 600 ℃ and 700 ℃. In opposite to soft burnt lime, HBL showed good fluidizing properties and little erosion. Since both CaO and Ca(OH)2 are widely used as aggregates in order to fix HC1 and catalyze the degradation of organic acids, the purpose of this research was the investigation of the impact on the product distribution and the ability of HBL to support the degradation of PET. Compared with experiments applied in the presence of quartz sand, the gas yield increased, while the wax fraction was strongly reduced. In the presence of HBL, the benzene yield rose strongly due to the decarboxylation of PET.
