ABSTRACT
The study examined the production of catalyst from a readily available biomass (chicken eggshell), for the pyrolysis process of waste PET bottles. Effective waste management and control is of high relevance in our modern society and this research work plays a vital role towards addressing plastic waste management through sustainable recycling practices. The Statistical analysis of the results shows that the use of this biomass derived catalyst enhances and facilitate the pyrolysis process of waste PET bottles, it had a significant effect on the Yield of Bio-oil production. The volume of oil recovered as the temperature increases in the absence of catalyst is less than that obtained in the presence of the catalyst. The characterization techniques involved includes XRF Analysis, XRD Analysis, FTIR Analysis, TGA Analysis and GCMS Analysis. From the values obtained, The XRF Analysis indicated the elemental composition of the calcined Eggshell, which revealed the presence of calcium(Ca) at 91.783% making it the most predominant element. The values obtained from the XRD Analysis showed the crystalline structure of the calcined eggshell and the Values obtained from the FTIR Analysis revealed the functional groups of the calcined eggshell, While the values obtained from the TGA Analysis Showed the results of the thermal degradation process of the treated catalyst. The GCMS Analysis showed the compound present and their composition of the liquid products. The volume of oil recovered at temperatures of (200, 210, 254, 300, 320, 350, 360, 380, 400) oC are: (0, 0, 1, 12, 28, 49, 67, 91, 123)ml respectively without the catalyst and (1,7,13,28,39,67,86,108,147)ml respectively with catalyst. This study has demonstrated the feasibility of utilizing biomass-derived catalyst in waste to energy processes and also emphasizes the potential for sustainable practices in the field of waste management.
