Steam bonding of solid lignocellulosic material.

摘要

Composite products (34) are formed, such as of lignocellulosic particles, by bonding through the transformation of added sugars and/or starches together with lignin and/or other phenolic containing materials, with the optional presence of added catalyst, the transformation causing the composition to convert into a furan-lignin type binder in situ by heat and pressure. The bonding composition is suitably activated by contact with live steam.
