(00750)Pyrolysis of Waste Plastic Laminates and Coconut Husk: Optimization of Fuel Oil Yield, Higher Heating Value and Energy Value

摘要

Alongside increasing use of single-use plastics, especially in developing countries is increasing mismanaged solid wastes. There is great need for economically viable processes such as pyrolysis that can convert waste to energy resource. Coconut husk, which is also an abundant waste in tropical countries is a good material for co-pyrolysis with single-use plastic, as both have high energy content. Thus, this study determines the potential of plastic laminates and coconut husk pyrolysis as feedstock for production of pyrolystic oil. It aimed to determine the effects of feedstock mixture composition (percent coconut husk: (32%, 42%, 51% coconut husk), process temperature (500oC, 600oC, 700oC)and particle sizes (1cm, 3cm, 5cm)on the percentage yield, gross calorific value and energy value of the output pyrolytic oil. Using RSM response optimizer, optimum oil yield is 32.5%, which is at feedstock of 50.42% coconut husk, 5-cm partcle size and 700oC. Feedstock of 32% coconit husk, 5-cm particle size and 700oC will give the highest HHV of 34.1142 MJ/Kg. Maximum energy of 6.0032 MJ will be obtained at feedstock of 51% coconut husk, 5-cm particle size and 700oC. ANOVA analysis showed that all the three parameters tested are significant factors affecting oil yield and energy yields. Temperature and percentage coconut husk have greater influences on yield, HHV and energy value than particle size.
