Method for converting biomass into products containing acetal groups and use thereof as biofuels

摘要

The invention describes a method of converting biomass to products that can be incorporated into the diesel fuel pool, comprising a first stage of fermentation of renewable raw materials of vegetable origin at the end of which a least one alcohol and at least one compound containing a carbonyl group are obtained, and a second stage corresponding to an acetalization reaction involving said alcohol and said compound containing a carbonyl group.

主权项

1. A method of converting alcohol compounds and carbonyl containing compounds resulting from biomass fermentation to acetal family products, comprising
a first stage (a) of fermentation of acetonobutylic (or ABE (acetone-butanol-ethanol)) and/or IBE (isopropanol-butanol-ethanol) type of renewable raw materials of vegetable origin, whereby a least one alcohol and at least one compound containing a carbonyl group are produced, and a second stage (b) of acetalization to produce an acetal or a mixture of acetal products from the at least one alcohol and at least one compound containing a carbonyl group obtained in stage (a), whereby the alcohol and the carbonyl compounds in the product are produced directly from ABE and/or IBE and ethanolic fermentations.
