The Effect of Pyrolysis Temperature and Size of Oil Palm Fiber Pellets on Biochar Production

Introduction

Biochar is a highly porous organic charcoal produced from the process of pyrolysis of biomass waste. The pyrolysis process involves heating biomass in the absence of oxygen, resulting in the production of biochar, which can be used as a renewable energy source, improve soil fertility, and store carbon, thereby mitigating climate change. In this study, the main focus is to convert oil palm fiber pellets into biochar by utilizing the pyrolysis process. The aim of this study is to explore how pyrolysis temperatures and pellet size affect the various biochar characteristics produced, including yields, water content, ash content, volatile material, fixed carbon, bulk density, and heat value.

Background

The palm oil industry is one of the largest industries in the world, producing millions of tons of oil palm waste every year. The waste generated from the palm oil industry is a significant environmental concern, as it can contribute to greenhouse gas emissions and soil degradation if not managed properly. Biochar production from oil palm waste can provide a sustainable solution to this problem, as it can be used as a renewable energy source, improve soil fertility, and store carbon.

Methodology

The experiment was carried out using 25 grams of oil palm fiber pellets. The size of the pellet used was varied to 4 cm, 2 cm, 1 cm, and 0.5 cm. The pyrolysis process was carried out at different temperatures, namely 300, 350, 400, 450, and 500 ° C, for 30 minutes using the Heraeus Muffle Furnace Kr 170. During the experiment, the data collected included yields, water content, ash content, volatile matter, fixed carbon, bulk density, and heat value of the resulting biochar.

Results

The results showed that biochar with a pellet size of 0.5 cm at 300 ° C produced the best results. The characteristics obtained include yield of 75.32%, water content of 1.54%, ash content 10.84%, volatile matter 45.44%, fixed carbon 42.16%, bulk density 1.57 g/cm³, and heat value 6,561,66 cal/g. In addition, the acquisition of biochar in this condition reached 18.83 grams, which was the highest acquisition in this study, produced a total heat of 123,556 cal.

Discussion

The importance of this research lies in the potential utilization of oil palm fiber waste as a renewable energy source. Biochar not only functions as a source of energy, but also has additional benefits in agriculture, such as increasing soil fertility and storing carbon, which helps in mitigation of climate change.

From the experimental results, it can be seen that the lower pyrolysis temperature (300 ° C) with a small pellet size (0.5 cm) provides a better yield and biochar quality. This may be caused by a more efficient pyrolysis process in describing fibers with small sizes at lower temperatures, so as to produce more useful solids compared to larger sizes or higher temperatures.

High pyrolysis temperatures, such as 450 ° C and 500 ° C, tend to reduce the volatile matter content, which indicates that the higher the temperature, the more substances are lost in the form of gas, thereby reducing the energy potential stored in biochar. Therefore, the selection of the right temperature and size of the pellet is very important to maximize the results of quality biochar.

Conclusion

Through this research, it is expected to make a significant contribution to the development of more efficient and environmentally friendly pyrolysis technology, as well as opening new opportunities in managing sustainable oil palm waste. By understanding the effect of the temperature and size of the pellet on biochar production, the palm oil industry can increase the added value of the waste produced and support efforts to reduce environmental impacts.

Recommendations

Based on the results of this study, it is recommended that the palm oil industry adopt a pyrolysis temperature of 300 ° C and a pellet size of 0.5 cm to produce high-quality biochar. Additionally, further research is needed to explore the potential of biochar in improving soil fertility and storing carbon, as well as its potential as a renewable energy source.

Limitations

This study has several limitations, including the use of a small sample size and the limited range of pyrolysis temperatures and pellet sizes used. Future studies should aim to increase the sample size and explore a wider range of pyrolysis temperatures and pellet sizes to provide a more comprehensive understanding of the effect of temperature and size on biochar production.

Future Research Directions

Future research directions include exploring the potential of biochar in improving soil fertility and storing carbon, as well as its potential as a renewable energy source. Additionally, further research is needed to explore the economic and environmental benefits of biochar production from oil palm waste.
