Abstract
The development of technology for biodiesel production is one of the attractive and challenging issues due to its possibility for commercial usage. Many patents have been investigated and proposed the intensification technology in order to improve and enhance the performance of biodiesel production process. In general, the invention topics mostly include feedstock materials, reactions, pretreatment technique, reactor/separation/purification technology and quality improvement. Therefore, this patent review summarizes the potential technology, development for biodiesel production presented in the mentioned topic and aims to keep the overview knowledge of the production process. Moreover, this review offers more clear comprehension and provides a guideline for further invention of any technologies for biodiesel production.
