Summary
A novel nickel/zeolite catalyst from geothermal waste efficiently converts waste cooking oil into biodiesel. This sustainable catalyst achieved an 89.4% yield under optimal conditions, demonstrating its potential for green fuel production.
Area of Science:
- Chemical Engineering
- Materials Science
- Environmental Science
Background:
- Waste cooking oil presents a significant environmental challenge.
- Developing sustainable catalysts is crucial for green chemistry and renewable energy.
- Geothermal solid waste is an underutilized resource with potential for catalyst development.
Purpose of the Study:
- To synthesize a sustainable nickel/zeolite (Ni/Zeolite) catalyst from geothermal solid waste.
- To optimize the transesterification process for biodiesel production from waste cooking oil.
- To evaluate the catalyst's performance, including yield and reusability.
Main Methods:
- Synthesis of Ni/Zeolite catalyst from geothermal solid waste.
- Characterization of the catalyst's physical properties (surface area, pore volume).
- Investigation of transesterification reaction parameters (catalyst concentration, temperature).
Main Results:
- The synthesized Ni/Zeolite catalyst exhibited increased surface area (80.661 m²/g) and pore volume (0.123 cc/g).
- Optimal biodiesel yield of 89.4% was achieved using 3% w/w catalyst at 60°C.
- Catalyst reusability showed a yield decrease to 73.3% after three cycles.
Conclusions:
- A sustainable Ni/Zeolite catalyst can be effectively produced from geothermal solid waste.
- The catalyst demonstrates high efficiency in converting waste cooking oil to biodiesel.
- Further research may focus on enhancing catalyst stability for improved reusability.
