Research on Thermal Cracking of Waste Deinking Aggregates for Pulping Environment Management

As the massive agent in the paper mills, deinking agent was wasted to pollute environment. What´s worse, wood extractives increased environmental pollution. Therefore, PyGC/MS was used to analyze the bioenergy resource of bamboo ethanol extractives. Relative content of each component was determined by area normalization. The ethanol extractives contain 117 compounds namely 2-furancarboxaldehyde, 5(hydroxymethyl) (7.06%), trimethylamine (5.64%), phenol, 2(1,1-dimethylethyl) (5.24%), benzofuran, 2,3-dihydro (4.95%), lupan-3-one (4.66%), phenol, 2,6-dimethoxy(4.47%), acetic acid (4.21%), phenol, 2-methyl (4.06%), 4H-pyran-4-one, 2,3dihydro-3,5-dihydroxy-6-methyl(4.00%), lH-pyrazole, 3,5dimethyl (3.87%), phenol (3.45%), 2-furancarboxaldehyde, 5-methyl (2.90%), phenol, 2-methoxy-4-(l-propenyl)(2.04%), etc. So the rare medicinal materials and rare spice is riched in the extractives of Moso bamboo, and the by-products can be used as not only top grade cosmetics and skin care, but also bio-energy.
