Title (EN) IMPROVEMENTS TO PROCESSES AND APPARATUSES FOR OBTAINING FURFURAL FROM PLANT MATERIALS
(FR) PERFECTIONNEMENTS APPORTES AUX PROCEDES ET AUX APPAREILLAGES POUR L"OBTENTION DE FURFURAL A PARTIR DE MATIERES VEGETALES
Abstract: front page image
(EN)Process and apparatus for producing furfural from plant materials. The hydrolysis of pentosanes contained in plant materials is effected in a first reactor (2) in the presence of a strong concentrated acid, at 20-70 C, at atmospheric pressure, and dehydration of the pentoses into furfural is effected in a second reactor (5) by vapor action at atmospheric pressure and at a temperature lower or equal to 110 C, in a strong acid concentrated medium. Application: production of furfural.
(FR)Procede et appareillage pour la production de furfural a partir de matieres vegetales. L"hydrolyse des pentosanes contenus dans les matieres vegetales est effectuee dans un premier reacteur (2) en presence d"un acide fort concentre, a 20-70 C, a la pression atmospherique, et la deshydratation des pentoses en furfural est realisee dans un deuxieme reacteur (5) par action de la vapeur a la pression atmospherique et a une temperature inferieure ou egale a 110 C, en milieu acide concentre. Application: production de furfural.
