摘要:
This invention relates to acetylation of wood. In particular, the invention provides methods of acetylation of solid wood in which at least some of the solid wood is processed in multiple acetylation cycles. The invention further provides wood acetylation methods that include sorting solid wood pieces based on density-indicating parameters.
摘要:
A commercial scale system and process for chemically modifying wood and then heating the chemically-modified wood. The system/process separates the chemical modification step from the heating step by utilizing two different vessels for the modification and heating steps. The system and process can, in certain situations, include a containment room for preventing escape of vapors from a chemical wood modification reactor, a wood heater, and/or a chemically-modified bundle of wood as the bundle is transported from the wood modification reactor to the wood heater.
