1. Esterification: Rohm & Haas has a solid catalyst
2. Transesterification: Mitsubishi has a solid catalyst
3. FFA's can be removed by saponifying them, centrifuging them out and restoring the FFA's through ion exchange. Then the FFA's can be processed into biodiesel using sulphonic catalysts like PTSA. THe problem with animal fats is the handling, the flow point, the sulfur content, the oxidation stability...FFA's are no problem.
4. Glycerol 'contaminated' with NaOH can be converted into propylene glycol, a very valuable byproduct, more valuable than pure glycerol.
5. The magic question: Where do I order such a reactor from Benefuel? Unless Benefuel really sells or licenses these reactors to the public, the article is kinda premature.
It reminds me about the article on photobioreactors from a Dutch company, which were loaded with algae from a pond-cultivated chlorella strain. Even the bottle of algae oil was borrowed. But it didn't stop Cleantech from publishing an article.
