Description
Technical field
The present invention relates to activated carbon manufacture technology field, the manufacture method of especially a kind of powdered biomass activated carbon。
Background technology
Activated carbon is a kind of porous carbonaceous material with flourishing pore structure and bigger serface, its physical and chemical performance is stable, mechanical strength is high, water insoluble and organic solvent, there is advantages such as being easy to regeneration, it is adsorbent and the catalyst carrier of a kind of function admirable, thus being widely used in the fields such as food processing, metallurgy, medicine, chemical industry, military affairs, environmental protection and the energy。The pore structure of activated carbon determines its physical and chemical performance, and owing to agricultural by-products amount charcoal processing rate big, inexpensive is high, and utilization economizes on resources and environmental protection, and therefore, many agricultural by-products may often be such that the primary raw material for preparing activated carbon。Walnut shell, also known as Semen Juglandis, Qiang's Fructus Persicae, for juglandaceae plant。With almond, Fructus anacardii, Semen coryli heterophyllae be called world-renowned " four big dry fruits "。Walnut shell and meat contains abundant nutrient, is the dry fruits liked of people, and after walnut shell takes off walnut shell and meat, remaining walnut shell, people, often when it is arbitrarily abandoned by rubbish, not only waste resource, also result in sanitary fill。At present, not yet find to utilize walnut shell as primary raw material and corresponding activator to prepare the report of powdered biological activated carbon。
Summary of the invention
Problem to be solved by this invention be to provide a kind of can the manufacture method of powdered biomass activated carbon of resource reutilization。
In order to solve the problems referred to above, the technical solution used in the present invention is:
Its method is for being ground into granule after being dried by walnut shell, this granule is mixed with the ratio that calcium hydroxide and potassium hydroxide are 1:1-5:0.05-0.20 in mass ratio, add water immersion, dry after expanded, dried mixture microwave irradiation is heated, then cools down, then soak with hydrochloric acid stirring, then with distilled water rinsing to neutral, dry；By drying object and AgNO3Solution mixing is soaked, and filters, then with distilled water flushing to neutral, then processes by steam water, final drying。
In technique scheme, scheme is it may also is that described drying is the heating, drying through 70 ° of C-100 ° of C more specifically；The particle diameter of described granule is 900-1200 order；The described time soaked is 3-5 hour；The concentration of described hydrochloric acid is 1.5mol/L, and the time adding soak with hydrochloric acid is 12 hours；Described AgNO3The concentration of solution is 0.05mol/L, described drying object and AgNO3Solution presses solid-to-liquid ratio 1:5；The temperature of described steam water is 180-200 DEG C, and the time that steam water processes is 2 hours。
Further: described microwave radiation heating process adopts nitrogen protection, first with heating rate for 10 ° of C/ seconds, heat to 230 ° of C-300 ° of C; rotate carbonization 30 seconds-50 seconds; then again with heating rate for 5 ° of C/ seconds, heat to 600 ° of C-800 ° of C, rotate carbonization 60 seconds-90 seconds。
Owing to have employed technique scheme, the present invention compared with prior art has the advantages that
1, the powdered biomass activated carbon that the present invention makes is adopted to have continuous print cavity passage, having the more uniform aperture of ratio, have great specific surface area, hole and duct account for the 50% of cumulative volume, make it have stronger ion-exchange capacity and absorbability, be good adsorbing material and antibacterial；There is relatively larger ion exchange capacity, and be loaded with catalyst Ag, it is possible to harmful substance in absorbed air and moisture。
2, using discarded walnut shell as raw material, it is to avoid the wasting of resources and decrease environmental pollution, there is environmental protection and promote the sound development of industry, and then widening plantation family and increase income channel。
