Investigation of the stability of Novozym® 435 in the production of biodiesel
The effect of the composition of the feedstock (free fatty acids and methanol), the presence or absence of moisture and the contact with biodiesel on the catalytic, enzymatic and physical stability of Novozym® 435 during enzymatic biodiesel production was studied. The continuous removal of moisture...
