Abstract

L'invention concerne un procédé particulier qui consiste à apporter un flux d'entrée comprenant du méthanol, un promoteur de condensation soluble capable d'activer un catalyseur hétérogène acide et une source de formaldéhyde; et à chauffer ce flux d'entrée avec le catalyseur acide hétérogène dans une colonne de distillation catalytique de manière à transformer le méthanol et le formaldéhyde présents en méthylal et en polyoxyméthylène diméthyléthers supérieurs, puis à séparer le méthylal des polyoxyméthylène diméthyléthers supérieurs. Le méthylal et les polyoxyméthylène diméthyléthers supérieurs sont formés et séparés dans une colonne de distillation catalytique. L'ajout au sein de la colonne d'une section contenant une résine d'échange d'anions permet d'obtenir un produit essentiellement exempt d'acide pouvant être directement utilisé comme composé de mélange ou fractionné, en vue d'une distillation ultérieure, de manière à obtenir des composés se prêtant mieux à une transformation en carburant diesel.
