US Patent:

60154403, Jan 18, 2000

Filed:

Oct 31, 1997

Appl. No.:

8/961939

Inventors:

Hossein Noureddini - Lincoln NE

Assignee:

Board of Regents of the University of Nebraska - Lincoln NE

International Classification:

C10L 118

US Classification:

44388

Abstract:

Triglycerides are reacted in a liquid phase reaction with methanol and a homogeneous basic catalyst. The reaction yields a spatially separated two phase result with an upper located non-polar phase consisting principally of non-polar methyl esters and a lower located phase consisting principally of glycerol and residual methyl esters. The glycerol phase is passed through a strong cationic ion exchanger to remove anions, resulting in a neutral product which is flashed to remove methanol and which is reacted with isobutylene in the presence of a strong acid catalyst to produce glycerol ethers. The glycerol ethers are then added back to the upper located methyl ethyl ester phase to provide an improved biodiesel fuel.

Abstract:

Triglycerides are reacted in a liquid phase reaction with a homogeneous basic catalyst and alcohol, such as ethanol or methanol. The reaction yields a spatially separated two phase result with an upper located non-polar phase consisting principally of transesterified triglycerides and a lower located phase consisting principally of crude glycerol and residual transesterified triglycerides. The transesterified triglycerides and/or glycerol phase is/are optionally, each separately passed through strong cationic ion exchanger(s) to remove anions, resulting in neutral product(s). The crude glycerol is then flashed to remove alcohol and is reacted with an etherifying agent, such as isobutylene or isoamylene, in the presence of a strong acid catalyst to produce glycerol ethers. The glycerol ethers are then added back to the transesterified triglycerides to provide an improved biodiesel fuel.
