Green biodiesel production from unrefined feedstock



Catalyst for green biodiesel production from unrefined feedstock

A durable catalyst for green biodiesel production from low grade feedstock through one-step catalysis has been developed, report scientists.

Biodiesel is a renewable liquid fuel originated from biomass, but it is not widely used because of its complicated production process and high cost. Since conventional liquid catalyst can only convert plant oil in its purest form into biodiesel, raw plant oil must be purified by adding strong acid or alkali before it can be used. To remove the added acid/alkali, the biodiesel must undergo a purification procedure which generates a huge amount of waste water. Therefore, a research team at The Hong Kong Polytechnic University (PolyU) has developed a new class of solid catalyst for biodiesel production.
