The present invention relates to a process for the production of ethanol from a carbonaceous feedstock, wherein the carbonaceous feedstock is first converted to synthesis gas which is then converted to ethanoic acid, which is then subject to a two stage hydrogenation process by which at least a part of the ethanoic acid is converted by a primary hydrogenation process to ethyl ethanoate, which ethyl ethanoate is converted by a secondary hydrogenation process to produce ethanol.
La présente invention concerne un procédé de production d'éthanol à partir d'une charge carbonée, la charge carbonée étant d'abord convertie en un gaz de synthèse qui est alors converti en acide éthanoïque, qui est ensuite soumis à un procédé d'hydrogénation en deux étapes par lequel au moins une partie de l'acide éthanoïque est convertie par un procédé d'hydrogénation primaire en éthanoate d'éthyle, lequel éthanoate d'éthyle est converti par un procédé d'hydrogénation secondaire pour produire de l'éthanol.
