Spanish researchers develop 20x faster one-step biodiesel process

In Spain, researchers at the University of Salamanca have developed and tested in a proof of concept the use of dodecylbenzenesulfonic acid as a catalyst for producing biodiesel from non-food sources in a single step. Traditional biodiesel production from non-food sources leads to foam production so it’s difficult to separate glycerin from the fuel so requires an expensive two-step process. This new process is up to 20 times faster and cheaper than the two-step process.
