High-quality biodiesel

Selective hydrogerration over low-loading, supported Cu catalysts has shown to be a valuable tool for the production of high quality biodiesel from Tall Oil, a byproduct of the Pulp Paper indrrstry. These resrrlts allow planning the use of a great variety of non-conventiorral oils with high iodine value for the production of biodiesel. 

In this chapter, we report just a few selected examples of heterogeneous catalytic systems for the esterification of fatty acids and for the simultaneous esterification and transesterification of acidic oils and fats, and we discuss the use of selective hydrogenation as a tool for the production of high-quality biodiesel from non-edible raw materials. 

We have reported our work in the field of selective hydrogenation for the production of high-quality biodiesel. To the best of our knowledge, this is the only example of such a process.

The purpose of this chapter is to introduce conventional methods in biodiesel production and their challenges, but the center of attention is on the novel technology used in biodiesel production, membrane reactors, in which both production and separation occur simultaneously. Membrane reactors have the ability to block the passage of unreacted TG to final biodiesel product. This phenomenon has the benefits of providing high-quality biodiesel fuel (Atadashi, Aroua, Abdul Aziz, 201 la).
