Le procédé de préparation de la suspension de biomasse à haute concentration comprend les étapes suivantes : 1) mélange d'un solvant non polaire, d'un émulsifiant et éventuellement d'eau dans une solution émulsifiée stable dans les états de chauffage et d'agitation ; et 2) mélange de manière homogène des particules de poudre de biomasse pulvérisées dans la solution émulsifiée, ou ajout de la solution émulsifiée pendant la fragmentation et le broyage de la biomasse afin de modifier les surfaces des particules de poudre. L'invention concerne également l'utilisation de la suspension de biomasse à haute concentration dans des domaines tels que la production d'énergie de biomasse et la préparation de gaz de synthèse à l'aide de la biomasse. La suspension de biomasse à haute concentration est obtenue par modification des particules de poudre de biomasse ; et la suspension obtenue peut être acheminée à l'aide d'une pompe à suspension vers des procédures actives en aval nécessitant une consommation d'énergie moindre, et une alimentation stable à haute pression est réalisée.
