A METHOD OF PRODUCING MICROCRYSTALLINE CELLULOSE FROM BIOMASS

A method of producing microcrystalline cellulose comprising the step of chlorinating pretreated fibers of empty fruit bunches of oil palm which have reduced oil content to acquire holocellulose followed by an alkaline extraction of said holocellulose to produce alpha-cellulose. The alpha-cellulose i...

Beschreibung
Zusammenfassung:A method of producing microcrystalline cellulose comprising the step of chlorinating pretreated fibers of empty fruit bunches of oil palm which have reduced oil content to acquire holocellulose followed by an alkaline extraction of said holocellulose to produce alpha-cellulose. The alpha-cellulose is then treated with an acid to form a hydrolysate mixture. Neutralizing the hydrolysate mixture affords microcrystalline cellulose. La présente invention concerne un procédé de production de cellulose microcristalline comprenant l'étape de chloration de fibres prétraitées de grappes de fruits vides de palmier à huile qui ont une teneur en huile réduite pour obtenir de l'holocellulose suivie d'une extraction alcaline de ladite holocellulose pour produire de la cellulose alpha. La cellulose alpha est ensuite traitée avec un acide pour former un mélange d'hydrolysat. La neutralisation du mélange d'hydrolysat produit de la cellulose microcristalline.
