Pyrolysis kinetics of palm oil mill effluent (pome) – based sludge / Yuganavasan Esuthasu

Abstract Dalam eksperimen ini, kita menggunakan efluen enapcemar(sludge) daripada kilang minyak kelapa sawit untuk eksperimen pirolisis. Efluen ini, boleh didapati dalam kuantiti yang banyak dan hargany juga murah. Eksperimen pirolisis ini dijalankan menggunakan peralatan “Thermogravimetric Analyzer” di bawah keadaan nitrogen (10mL/min). Kesan kadar pemanasan (5, 10 dan 15 °C/minit) telah digunakan untuk menyiasat parameter (tenaga pengaktifan, factor kekerapan dan perintah reaksi) menggunakan persamaan Arrhenius. Melalui eksperimen ini, ia telah deperhatikan dengan jelas bahawa kelakuan kinetic oleh enapcemar boleh dibahagikan kepada tiga zon yang berbeza. Zon pertama adalah pada suhu sekitar 220°C hingga 420°C, manakala 420°C hingga 550°C untuk zon kedua dan 550°C hingga 830°C untuk zon ketiga. Daripada analisis, didapati bahawa zon pertama dan kedua menjalani perintah kedua tindak balas sementara, zon ketiga terakhir adalah sifar bagi tindak balas. Nilai-nilai tenaga pengaktifan yang diperolehi dengan kaedah ini untuk zon I, II dan III adalah dalam lingkungan 34-41 , 25-80 dan sekitar -12 kJ/mol masing-masing. _______________________________________________________________________________________________________ Pyrolysis of Palm Oil Mill Effluent (POME) based sludge, a cheap and abundantly available solid-liquid waste resulted from palm oil producing process, was carried out using thermogravimetric analysis under a nitrogen environment (10mL/min). The effect of heating rates (5, 10 and 15°C/min) on the kinetic parameters (activation energy, frequency factor and reaction order) was investigated using Arrhenius equation. It was clearly observed that the kinetic behavior of the samples can be divided into three distinct zones. The first zone was in the temperature around 220°C to 420°C, while 420°C to 550°C for the second zone and 550°C to 830°C for the third zone. From the analysis, it was found that the first and second zones undergo second order of reaction while the last, third zone was zero order reaction. The activation energy values obtained with this method for zones I, II and III were in the range of 34-41, 25-80 and around -12 kJ/mol respectively.
