Catalytic boost for cheaper biodiesel production
Sub: Environment
Sec: Int Conventions
Development of Cost-Effective Water-Repellent Catalyst for Biodiesel Production:
- Scientists from Assam, Odisha, China, and the UK have developed a water-repellent catalyst to reduce the cost of producing environmentally friendly biodiesel.
- The research on the “spherical superhydrophobic activated carbon catalyst” has been published in Advanced Functional Materials.
Research Team:
- Arpita Das, Kangkana Saikia, Samuel Lalthazuala Rokhum (NIT Silchar, Assam)
- Chandrakanta Guchhait, Bimalendu Adhikari (NIT Rourkela, Odisha)
- Da Shi (University of Cambridge, UK)
- Hu Li (Guizhou University, China)
Key Features of the Catalyst:
- The catalyst mimics the water-repelling properties of lotus leaves, preventing the poisoning of active sites by water produced during biodiesel production.
- It is derived from biomass (cellulose), making it eco-friendly, abundant, and affordable.
- It is highly robust and can withstand the water by-product, enhancing its effectiveness and reusability.
Biodiesel:
- Biodiesel is a liquid fuel produced from vegetable oils and animal fats through transesterification.
- It is used as a replacement or as a blending with petroleum-based diesel in various combinations such as B5, B20, B100, etc.
- B20 (commonly used due to cost-effectiveness, low emissions and compatibility with conventional engines) is a blend containing 20% biodiesel and 80% petroleum diesel.
- B100 (less commonly used) is a pure biodiesel.
Impact on Biodiesel Production:
- The novel catalyst significantly reduces the cost of biodiesel production.
- Current biodiesel costs in India are around ₹100 ($1.2) per litre; the new catalyst can reduce this to approximately 37 cents per litre.
- This makes biodiesel a more cost-effective and sustainable energy source compared to diesel, which costs at least ₹87 per litre in India.
Significance:
- The catalyst improves the efficiency and cost-effectiveness of the biodiesel production process.
- It supports broader adoption of biodiesel, contributing to a greener future.
- The green synthesis strategy offers a sustainable method for biomass waste disposal and enhances the utility of biochar as an alternative to graphene and carbon nanotubes.
