摘要

This study provides a novel methodology for biodiesel (FAME) production under ambient pressure, which resolves most drawbacks of current commercialized biodiesel conversion via the transesterification reaction. This has been achieved by means of a thermo-chemical process and a true continuous flow system. This also enables combination of esterification of free fatty acids (FFAs) and transesterification of triglycerides into a single process without utilizing a catalyst, and leads to a 98-99 卤 0.5%conversion efficiency of FAME within 1 min in the temperature range of 350-500 掳C. High FFA content in oil feedstock is not a matter of the new process, which enables the use of a broader variety of feedstocks, including all edible and inedible fats. Another feature of this novel method is that it does not produce wastewater. Thus, the new process has potential to spur a breakthrough in the lowest cost of biodiesel production. Moreover, this method also requires utilization of carbon dioxide during biodiesel production, an additional environmental benefit.
