Abstract

The present invention discloses a method for increasing the hardness and dimensional stability of wood, in one embodiment the method comprises subjecting the compressed lignin to temperature cycling at a compression temperature between 120 C° and 230 C° And slowly cool it under low pressure environment.

Description

[0001] Cross-reference related patent applications [0002] This application claims the priority of the prior US patent application No. 62 / 069,921, which was filed on October 29, 2014, and the description of the aforementioned application is incorporated herein by reference in its entirety. Background technique [0003] Carbonization is a gentle way to crack liquid wax, tar and dust and extract their volatile components. These compounds are harmful to the environment and need to be destroyed or recycled according to specific processes. The invention discloses a production process for how to control the waste of compounds and safely convert them into recyclable energy. [0004] As we all know, charring is a process to make wood more durable. Simply burning the surface of the wood can make it more durable. The key of the present invention is to improve the quality and durability of wood by improving the carbonization process. [0005] Carbonization requires heating the wood at very h...
