Selectively depolymerizing cellulosic materials for use as thermal and acoustic insulators |
| abstract |
The present invention relates to the creation of thermally insulating materials derived from cellulosic materials by selectively depolymerizing the materials anatomy. Cellulosic materials may be comprised of three main biopolymers: lignin, hemicellulose, and cellulose. The present invention relates to the chemical and physical removal of lignin and hemicellulose, while leaving the cellulose unaltered to induce increased porosity within the material and the material's macrostructure matrix for use as thermal and acoustic insulation. The increased porosity will be due to the creation of closed cell voids within the cellulosic matrix. These voids will increase the thermal and acoustic insulating performance of the cellulosic materials. The selective removal of secondary biopolymers from cellulosic materials allow for isolation of other value added products that can be regenerated through fewer reactions/steps. This is a novel advantage over other similar processes that dissolve cellulose completely, making it harder to extract and isolate secondary off-stream products. |
