Process for Preserving Wood Chips During Storage.

摘要

This patent application deals with a process which limits the loss of wood substance,brightness and tall oil in wood chips during storage. The process involves treating wood chips with a dilute aqueous solution of sodium bisulfite and a phenol. This treatment effectively prevents chip pile heating and microbial growth and thus limits chip deterioration and brightness loss while preserving tall oil. The process is also effective with any other moist plant-derived raw material.
