Abstract
A process for preparing biodiesel having improved filterability characteristics including inducing transesterification of a triglyceride feedstock with cavitation to form an intermediate reaction product. Glycerol by product is separated from the intermediate reaction product before finishing the transesterification reaction in a pressurized reaction tank to yield a biodiesel reaction product. The biodiesel reaction product can be further purified by removing glycerol.

A process for preparing biodiesel having improved filterability comprising:
- mixing a triglyceride feedstock, alcohol and catalyst to form a pre-reaction mixture;
- forming an intermediate biodiesel reaction mixture comprising fatty acid alkyl esters and glycerol by passing the pre-reaction mixture through a static hydrodynamic cavitation reactor to induce an initial transesterification reaction in said pre-reaction mixture, wherein more than 60 weight percent of said triglycerides in said pre-reaction mixture are converted, wherein the cavitational energy to the pre-reaction mixture does not include the use of ultrasound cavitational energy;
- removing a portion of said glycerol from said intermediate biodiesel reaction mixture;
- completing the initial transesterification reaction by agitating said intermediate biodiesel reaction mixture in a pressurized reaction tank to form a biodiesel reaction product.
