Description

Technical description

This invention describes a process for converting vegetable oils and ethanol into a mixture of biodiesel and glycerol ethers in one heterogeneous catalytic step. The catalytic system used promotes as well the transesterification reaction with ethanol and the etherification of glycerol with ethanol.

Benefits

This invention combines four main advantages compared to the usual processes based on homogeneous or heterogeneous basic catalysts :

– Glycerol ethers are obtained using a cheap, non toxic and biosourced alcohol.

– Crude or used vegetable oils may be used since the heterogeneous catalyst is not sensitive to free acids.

– The difficult step of glycerol separation is avoided since glycerol ethyl ethers are simultaneously produced with biodiesel.

– Thus, the biofuel yield produced from vegetable oils and ethanol is increased by 10%.

Industrial applications

Applications include: the conversion of crude or used vegetable oils into a biofuels mixture composed of fatty acid ethyl esters and glycerol ethyl ethers, etherification of crude glycerol to produce oxygenate additives to gasoline or biofuels.
