Thesis Overview

The project "Optimization of Biofuel Production from Algae Biomass Using Supercritical Fluid Extraction" aims to explore a sustainable and efficient method for biofuel production by utilizing algae biomass and supercritical fluid extraction technology. Algae, as a promising feedstock for biofuel production, offers several advantages such as high growth rates, minimal land use, and the ability to grow in various environments. However, the extraction of biofuels from algae biomass presents challenges, including low extraction efficiency and high energy consumption. Supercritical fluid extraction is a cutting-edge technology that offers a promising solution to these challenges. By using supercritical fluids such as carbon dioxide, extraction processes can be optimized to achieve higher yields, reduced solvent usage, and shorter extraction times. This project seeks to investigate the optimal conditions for extracting biofuels from algae biomass using supercritical fluid extraction, with a focus on maximizing efficiency while minimizing environmental impact. The research will consist of several key components, including a comprehensive literature review to analyze previous studies on algae biofuel production and supercritical fluid extraction techniques. The methodology will involve experimental work to determine the most effective parameters for the extraction process, such as temperature, pressure, and solvent composition. The findings from the experiments will be discussed in detail to highlight the efficiency and feasibility of the proposed method. Overall, this project aims to contribute to the field of biofuel production by providing a sustainable and cost-effective approach to extracting biofuels from algae biomass. By optimizing the extraction process using supercritical fluid technology, this research has the potential to enhance the viability of algae-based biofuels as a renewable energy source for the future.
