METHOD FOR IMPROVING YIELD OF ENZYMATIC PREPARATION OF BIODIESEL FROM GREASES

摘要

Provided in the present invention is a method for improving the yield of enzymatic preparation of biodiesel from greases, comprising: during enzymatic reaction of short-chain alcohols with greases to prepare biodiesel, introducing online dehydration steps, which lead the volatile gases in the enzyme reactor to enter into the low-temperature absorption tank, and the dehydrated gases flow back into the enzyme reactor. The formation of gas-circulation can constantly bring the moisture inside the enzyme reactor out.

1. A method for improving the yield of enzymatic preparation of biodiesel from greases comprising:
enzymatically reacting short-chain alcohols with the greases in an enzyme reactor to prepare biodiesel, circulating volatile gases produced in the enzyme reactor to enter into a low-temperature absorption tank, dehydrating the volatile gasses in the low temperature absorption tank, and circulating the dehydrated volatile gases back into the enzyme reactor; wherein the steps of circulating and dehydrating the volatile gasses constantly brings moisture inside the enzyme reactor outside of the enzyme reactor, so as to improve the conversion rate of the reaction.
