Introduction

The world is shifting towards alternative energy sources, and one of the most promising options is Gasohol E-85, a biofuel that contains 85% ethanol. This study focuses on making Gasohol E-85 fuel by adding calcium oxide (CAO) as a breakdown of the Azeotrop ethanol-water point. The use of CAO in the bioethanol purification process offers an innovative approach to improve the quality of this fuel. In this article, we will delve into the process of making Gasohol E-85 fuel, its analysis, and the importance of this research in the development of alternative fuels.

The Role of Calcium Oxide in Bioethanol Purification

Calcium oxide (CAO) plays a crucial role in the bioethanol purification process. It functions to bind water, separate water from ethanol during the distillation process, and reduce the boiling point of bioethanol from 78 ° C to 72 ° C. The use of CAO in the purification process is essential in producing high-purity bioethanol. In this study, the calcium oxide used is analyzed using SEM-EDX, which shows that the constituent atoms of calcium oxide consist of 37.59% carbon (C), 35.90% calcium (Ca), and 19.34% oxygen (O).

Analysis of Bioethanol Using FT-IR, GC-MS, and RON Test

After the refining process with calcium oxide, the resulting bioethanol is analyzed using FT-IR, GC-MS, and RON test. The results of the FT-IR analysis show that bioethanol before the addition of CAO has a summit of the uptake on the wave number 3317.33; 2907.32; 2884.95; 1416.38; 1379.11; and 1043.65 cm-1, each indicating the presence of functional -OH (stretching), C-H (asymmetrical stretching), C-H (symmetrical stretching), and C-O (stretching). After the addition of calcium oxide, a decrease in absorption intensity in the OH group in the wave number 3317.33 cm-1, which shows that the water content in bioethanol is reduced.

Effect of Calcium Oxide on Bioethanol Properties

Further analysis shows that the bioethanol octane number decreases from 120 to 109. This occurs because the air and water content in bioethanol is significantly reduced after processing. In addition, Bioethanol that has been added by CAO also shows an increase in solubility with pertalite compared to the initial bioethanol. This is caused by a smaller difference in density than bioethanol before the addition of calcium oxide. After going through azeotropic distillation, the resulting bioethanol has 100% purity.

Importance of This Research

The importance of this research lies in its contribution to the development of alternative fuels that are more efficient and environmentally friendly. Gasohol E-85, which contains 85% ethanol, can be used as a substitute for fossil fuels and reduce greenhouse gas emissions. The use of calcium oxide in the bioethanol purification process offers an innovative approach to improve the quality of this fuel. With high purity and better nature, Gasohol E-85 can be a promising solution in efforts to go to energy sustainability.

Future Research Directions

Seeing the existing potential, further research is needed to explore various combinations and modifications that can further improve the performance and efficiency of the fuel manufacturing process. In the future, alternative fuel uses such as Gasohol E-85 will not only provide more environmentally friendly choices, but also support national energy security.
