Enzymatic process does not require any degumming, caustic, and does not produce soap. Glycerin is a much higher quality and methanol usage is lower than traditional transestification process.
This should provide you with more information on the
enzymatic biodiesel production process and show you how to drive
down cost and increase profits using enzymes for your production
capabilities, and what the next steps are to implement the enzymatic
The Enzymatic Biofuel system improves conversion economics in nine ways:
1. Biodiesel is easier to separate from crude glycerin because of the absence of emulsifying soaps.
2. The use of low grade oil feedstocks, especially those with Free Fatty Acid higher than 3% and even up to 100% can now be employed.Low-grade oil feedstocks with FFA content as high as 100 percent can now be processed into ASTM biodiesel
3. Very little waste, Traditional caustic transesterification results in large amounts of alkaline toxic waste and complexity in downstream processing.
4. Low-grade oils can now be used without significant pretreatment.
5. Virgin oils no longer need to be degummed.
6. Catalysts are typically not reusable, Enzymes in the process have a 12 month shelf life.
7. Crude glycerin is significantly free of contaminants and can be more readily refined.
8. Precision E2500 Biodiesel Production Unit yields $0.20 per gallon processed feedstock.
9. No heating is required, so much less energy is consumed.
Esterification or Transesterification
The enzymatic process is a direct replacement for WVO feedstock pretreatment using acid esterification, sulfuric acid, or solid acid catalysts, and generates a dry (<1500ppm water), low FFA (<1%) feedstock ready for transesterification. For very high FFA feedstocks like acid distillates or brown grease, this process is very cost effective.
We have successfully scaled up our enzymatic transesterification process into a commercial Precision E2500 Biodiesel Production Unit using Enzymes. Biodiesel producers interested in implementing enzyme catalysts for existing or future transesterification production facilities can contact us directly for a site evaluation.
Your plant can first invest in the enzymatic equipment for feedstock pretreatment, or you can implement a complete enzymatic biodiesel solution using the enzymes for transesterification.
We are inviting companies interested in the enzymatic process to send us a 5 gallon oil sample to test on a lab scale. We already have extensive data on yellow grease (used cooking oil), brown grease, corn oil, and palm fatty acid distillate.
