description A method of increasing the throughput and/or decreasing the energy usage of a pulping process includes the steps of providing a plurality of lignocellulosic chips, providing a refining composition, applying the refining composition to the plurality of lignocellulosic chips, and mechanically refining the plurality of lignocellulosic chips to form pulp. The refining composition includes water and a lubricating additive comprising the reaction product of a sugar and an alcohol. The step of applying the refining composition to the lignocellulosic chips is conducted less than 5 minutes prior to, or concurrently with, the step of mechanically refining the wood chips to form pulp. La présente invention concerne un procédé d'augmentation du débit et/ou de diminution de l'utilisation d'énergie d'un processus de réduction en pâte qui comprend les étapes consistant à fournir une pluralité de copeaux lignocellulosiques, à fournir une composition de raffinage, à appliquer la composition de raffinage à la pluralité de copeaux lignocellulosiques, et à raffiner mécaniquement la pluralité de copeaux lignocellulosiques pour former de la pâte à papier. La composition de raffinage comprend de l'eau et un additif lubrifiant comprenant le produit de réaction d'un sucre et d'un alcool. L'étape d'application de la composition de raffinage aux copeaux lignocellulosiques est effectuée moins de 5 minutes avant, ou simultanément à, l'étape de raffinage mécanique des copeaux de bois pour former de la pâte à papier.
