The effect of plastic type on the yield and quality of lignite and plastic waste pyrolysis products

Abstract Lignite is a low rank coal which has great potential in South Kalimantan. However, it has not been used optimally due to its low quality. One of the ways to improve it is pyrolysis. Pyrolysis is the thermal decomposition of organic material in the absence of oxygen which will produce three products (char, tar and gas). Pyrolysis can make lignite into liquid fuel (pyrolysis liquid), but it still requires improvement due to the need for pure hydrogen donors. Plastic waste has a higher hydrogen/carbon ratio than coal. This material can be used as an additive in the pyrolysis process because it is rich in hydrogen. The samples of plastic waste used were ppolyethylene (PE), ppolypropylene (PP), and polystyrene (PS). Samples of lignite and plastic (plastic composition was 25 wt%) were used for every experiment, and pyrolysis was carried out with a holding time of 60 minutes at 500°C. The pyrolysis liquid obtained is then analyzed for its yields and properties (density, kinematic viscosity, heating value). The most feasible result for fuel alternative was obtained with the addition of PE.

Fuel Pyrolysis

Indonesia is one of the biggest plastic waste production in the world. The government targets to reach 20% for recycling plastic waste in 2019. One alternative to manage plastic waste is using pyrolysis to produce fuel. Pyrolysis is used to degrade the plastic long chain of polymer molecules into smaller molecules. All type of plastic except polyvinyl chloride (PVC) were used in this study to produce fuel. For the purpose, experiment factorial design was used for the optimisation plastic type, residence time, and temperature to maximise the yield of liquid products of the pyrolysis process. In this study 2k factorial design was used for each factor. The result shows that the pyrolysis process used is able to produce diesel like fuel in low temperature.

Fuel Pyrolysis

ENGLISHThe amount of waste generation continued to increase in Indonesia due to economic development and population growth. In addition, the diversity of solid waste becomes another problem since products made from plastics became widely used and were discarded in large amounts. Plastic waste can be converted into fuel through pirolisis in order to reduce the amount of plastic waste as well as to produce alternative fuel. Pyrolysis is a process of thermal degradation in the absence of oxygen. The objective of this study is to investigate and to compare the performace of fuel produced by pyrolisys, kerosene and diesel oil. The performance of those fuels is investigated in 4 parameters including density, burning time, temperature of water and the volume of water evaporated. The result of this study are 1) the density 0.8 g/ml; burning time 4.02 minutes; water temperature 75°C and water evaporated 12.6 ml. 2) Compared to kerosene and diesel oil, the quality of the fuel is lower than kerosene and higher than diesel oil in all parameters. INDONESIAPertumbuhan penduduk dan ekonomi menyebabkan terjadinya peningkatan produksi sampah khususnya sampah plastik. Pirolisis merupakan proses perekahan atau pemecahan rantai polimer menjadi senyawa yang lebih sederhana melalui proses thermal (pemanasan/pembakaran) dengan tanpa maupun sedikit oksigen. Sampah plastik bisa diurai dan diubah menjadi bahan bakar yang memiliki nilai kalor yang tinggi melalui proses pirolisis. Penelitian ini bertujuan untuk mengetahui dan membandingkan kemampuan minyak hasil pirolisis plastik dengan minyak tanah dan solar dalam hal massa jenis, lama pembakaran, temperatur air dan volume air yang hilang (menguap) saat dimasak menggunakan minyak tersebut. Hasil penelitian menunjukkan bahwa 1) massa jenis minyak pirolisis adalah 0,8 g/ml. Waktu yang dibutuhkan untuk membakar habis suatu benda adalah 4,02 menit. Pemasakan air menggunakan bahan bakar minyak pirolisis menghasilkan temperatur 75°C pada waktu pemasakan 4 menit dengan volume air yang hilang (menguap) sebesar 12,6 ml. 2) Dari 4 parameter yang diamati, kualitas minyak pirolisis berada di bawah minyak tanah namun di atas minyak solar.

Experimental Design Method

Plastic waste is one type of waste that can not be broken down into the organic waste. Utilization of waste plastics to berecycled into plastic with better quality are rarely implemented. This study aims to utilize plastic waste in order to improve the quality of plastic products by Taguchi experimental design method that combines the pure plastic material composition of ore and recycled plastic (type PP/Polypropilena) with a certain pressure and temperature to produce a tensile strength of the plastic the better. From the experimental results, obtained by a combination of material composition of 30% recycled plastic, the pressure of 6.5 atm and a temperature of 180 °C. The composition obtained by the average tensile strength of 991.667 Newton, and Signal to Noise ratio (Larger is better) by 59, 9255. Statistically, tur ulang he combination was significantly affected by alpha at 0:05 Taguchi method through experiments with a matrix orthogonal array L8 (23).
