The Effect of Adsorption Temperature on the Quality of Used Cooking Oil by Active Charcoal of Hazelnut (Aleurites Moluccana) Activated with H2SO4 10%

Introduction

Repeated use of used cooking oil can cause various health problems due to the accumulation of free fatty acids, water content, and other contaminants. Therefore, an effective method is needed to clean and improve the quality of used cooking oil. One method examined is adsorption using active charcoal. This study uses active charcoal candidate shell (Aleurites moluccana) which is activated with 10% H2SO4 to absorb used cooking oil.

Preparation of Active Charcoal

The process of making active charcoal begins with dehydration and carbonization of hazelnut shells at 750 ° C for 90 minutes. The carbonization charcoal is then sifted with 100 mesh sieves to get active charcoal that passes the sieve. This active charcoal is then activated with 10%H2SO4. The characterization of active charcoal shows a yield of 32.845%, water content 6.88%, and ash content of 0.49%. Active charcoal surface morphology is analyzed using Electron Microscopy (SEM) scanning, while the particle size is measured using a Particle Size Analyzer (PSA) which shows an average size of 104,43677 μm.

Adsorption Process

The quality of used cooking oil tested using active charcoal is analyzed based on free fatty acid levels (FFA), water content, density, and refractive index. The results showed that the higher the temperature of the adsorption, the better the quality of used cooking oil produced. This shows that the temperature of the adsorption has a significant effect on the adsorption process and the quality of used cooking oil adsorpted.

The Effect of Adsorption Temperature on the Quality of Used Cooking Oil

The following is a more detailed explanation of the effect of adsorption temperature on the quality of used cooking oil:

Increasing the Absorption of Active Charcoal

Higher adsorption temperature can increase the absorption of active charcoal. This is because the kinetic energy of the molecules increases at higher temperatures, so that adsorbed molecules are more easily moved and enter the pores of active charcoal.

Increasing the Speed of Adsorption

A higher temperature can also speed up the adsorption process. This is because the activation energy for the adsorption process is reduced at higher temperatures, so the adsorption reaction takes place faster.

Increasing the Efficiency of Adsorption

Adsorption efficiency can increase at higher temperatures because more molecules are adsorbed in a shorter time.

Affecting the Quality of Used Cooking Oil

Increasing the efficiency of adsorption has a positive impact on the quality of used cooking oil. This can be seen from the decrease in free fatty acid levels (FFA), water content, and an increase in density and refractive index. A decrease in FFA levels shows that active charcoal is able to absorb fatty acids that are free due to recurring frying processes.

Conclusion

This study indicates that the use of active charcoal of the Candlenut shell activated with 10% H2SO4 can be an effective solution to improve the quality of used cooking oil. Adsorption temperature is an important factor that affects the efficiency and quality of adsorption. Adsorption temperature optimization can be done to get optimal adsorption results and produce used cooking oil with better quality.
