Abstract
The invention provides an artificial granulation method for a wood granular active carbon raw material without addition of highly acid substances like zinc chloride, phosphoric acid, hydrochloric acid and sulfuric acid for acid hydrolysis and saccharification. The invention is characterized in that the artificial granulation method for the wood granular active carbon raw material is realized by using lignin, which is dissolved out from the raw material wood powder under the action of a high boiling solvent, as an adhesive. The high boiling solvent used in the invention refers to an alcohol with a boiling point higher than 180 DEG C, and high boiling solvents frequently used in industry comprise butylene glycol, propylene glycol and glycol. The raw material wood powder used in the invention refers to a biomass material simultaneously containing cellulose and lignin and comprises pine, China fir, bamboo, broad-leaf weed tree, fruit shells and crop straw frequently used in industry.
Description
Technical field
The present invention relates to Activated Carbon Production field, particularly a kind of artificial granulation's method of wood substance grain activated carbon raw material.
Background technology
Accessibility for transport, storage, use is considered; granular active carbon is more received by the market than powdered active carbon; only shell in natural materials; mainly Exocarpium cocois (Cocos nucifera L) just can production indefinite form granular active carbon; resource is restricted, so need the source being expanded wood substance grain activated carbon raw material by artificial granulation.
Adopting external source tackiness agent artificial granulation to bring contradiction between granular active carbon physical strength and specific surface area to improve, proposing the artificial granulation's method adopting raw material wood powder self leachable to make tackiness agent; Patent of invention " a kind of manufacture method of wooden quality granule shape activated char used in recovering solvent " (02122974.0), " wooden vehicular active carbon and preparation method thereof " (03125474.8), " method of low temperature directional preparation high specific surface area wood-pellets gac " (201110033145.8) be proposed utilize Lvization ?, phosphoric acid, hydrochloric acid can also be added, sulfuric acid makes xylogen acid hydrolysis saccharification stripping in raw material wood powder make artificial granulation's method of tackiness agent, obtains high mechanical strength and high-specific surface area artificial granulation wood activated charcoal all better; But this is all only applicable to chemical method and prepares wood activated charcoal.
Summary of the invention
The object of the invention be to provide a kind of can artificial granulation's method of wood substance grain activated carbon raw material of preparing of Physical, namely need not add artificial granulation's method that the Strong acidic substance such as zinc chloride, phosphoric acid, hydrochloric acid, sulfuric acid carry out the wood substance grain activated carbon raw material of acid hydrolysis saccharification react, it is characterized in that utilizing xylogen in the high alcohol stripping raw material wood powder that boils to realize artificial granulation's method of wood substance grain activated carbon raw material as tackiness agent;
The height of the present invention alcohol that boils refers to that boiling point is higher than the alcohols of 180 DEG C, and industrial conventional have butyleneglycol, propylene glycol, ethylene glycol;
Raw material wood powder of the present invention refers to the biological material of simultaneously cellulose and xylogen, and industrial conventional have pine, China fir, bamboo, broad-leaved weedtree, shell, farm crop tangerine bar;
Beneficial effect
Avoid the Strong acidic substance such as zinc chloride, phosphoric acid, hydrochloric acid, sulfuric acid to equipment corrosion and environmental pollution, filled up adopt raw material wood powder in advance artificial granulation's Physical prepare the blank of wood substance grain gac.
Accompanying drawing explanation
Fig. 1 utilizes xylogen in the high alcohol stripping raw material wood powder that boils to realize artificial granulation's process flow sheet of wood substance grain activated carbon raw material as tackiness agent.
