Fuels and fuel additives production from glycerol conversion using a monohydric alcohol and heterogeneous catalysis

摘要

The present disclosure relates to a method of converting glycerol into organic reaction products. The method may include mixing glycerol with a monohydric alcohol. The mixture of glycerol and monohydric alcohol is then reacted in the presence of a heterogeneous nano-structured catalyst, wherein the monohydric alcohol is present at subcritical/supercritical temperatures and pressures. This converts the glycerol into one or more reaction products, wherein the reaction products include an oxygenated organic reaction product. Ninety percent or greater of the glycerol is converted.

主权项

1. A method of converting glycerol, comprising:
mixing glycerol containing hydroxyl groups with methanol; reacting said glycerol and methanol in the presence of a heterogeneous nano-structured catalyst, wherein said methanol is present at a temperature of 200° C. or greater and a pressure of 1,140 psia or greater; converting said glycerol into one or more reaction products, wherein one or more of said hydroxyl groups of said glycerol is converted into alkyl, alkyl ether, carbonyl, cyclic ether or alkene functionality; and wherein 90% or greater of said glycerol is converted to said reaction products containing said converted hydroxyl functionality.
