Corn bran-based three-dimensional multi-level pore structure carbon material and preparation method thereof

The invention relates to a corn bran-based three-dimensional multi-level pore structure carbon material and a preparation method thereof, which belong to three-dimensional multi-level pore structure carbon materials. According to the corn bran-based three-dimensional multi-level pore structure carbon material and the preparation method, renewable biomass corn bran with low price and rich yield is adopted as a carbon source, the novel three-dimensional multi-level pore structure carbon material is effectively prepared by adopting a simple template-free method which is easy to industrialize, and the problems of process complexity, time consumption, high cost and difficulty in realizing industrialization of a template method are solved. The corn bran-based three-dimensional multi-level pore structure carbon material is prepared in the following steps of cutting the corn bran into pieces, drying after water washing treatment, then adding to a KOH solution, returning under a water bath condition, sieving after cooling, then roasting solids in high-purity nitrogen atmosphere, then cleaning with a hydrochloric acid solution, centrifuging, washing with water and drying. The specific surface area of the carbon material reaches up to 927m<2>g-1, macropore, mesopore and micropore structures are mutually communicated, the pore size distribution is centered, an oxygen enrichment functional group is contained, and the content is 12% to 17%.

High-content bacterium-coated biological fertilizer and preparation method thereof

The invention provides a high-content bacterium-coated biological fertilizer and solves the problems that the existing biological fertilizer is low in content of organic matters and low in content of beneficial bacteria, the growth requirements of plants cannot be met, and the content of heavy metals exceeds the standard. The high-content bacterium-coated biological fertilizer is prepared from the following raw materials: furfural residue, humic acid, kiln dust, bacillus subtilis, bacillus licheniformis, bacillus mucilaginosus, zinc sulphate monohydrate and boric acid. A preparation method of the high-content bacterium-coated biological fertilizer comprises the following steps: firstly mixing the furfural residue and humic acid, fermenting and decomposing, then adding the kiln dust and microelements and stirring, then pelleting and drying, and finally coating and filling to obtain the high-content bacterium-coated biological fertilizer. The high-content bacterium-coated biological fertilizer has the effects of increasing yield and efficiency, improving soil hardness, inhibiting diseases and insect pests, reducing application quantities of chemical fertilizers and accelerating growth of the plants; when the high-content bacterium-coated biological fertilizer is applied to fruit trees, the fruit trees can bloom regular flowers, the flowers and the fruits can be retained, and the leaf fall period is late; the high-content bacterium-coated biological fertilizer is capable of resisting early spring diseases, preventing and treating premature senescence, resisting lodging, resisting drought and cold and reducing pollution to the environment; the content of the bacteria in the biological fertilizer produced by the method reaches one billion per gram; the content of the organic matters in the biological fertilizer reaches up to 80%.

Carbonized heating supply system for rod production from forestry waste

PendingCN108048118AGood for kiln body temperatureConducive to maintaining or improvingBiofuelsSpecial form destructive distillationCarbonizationHot pressing
The invention discloses a carbonized heating supply system for a rod production from forestry waste. The carbonized heating supply system comprises a rod-making device consisting of a primary crushingmechanism, a fermentation yard, a feeding mechanism, an air drying mechanism, a screening mechanism and a hot pressing rod-making mechanism in sequence. An inner cavity of a roller of the air dryingmechanism is divided into three layers of inner and outer casing structures and is provided with positive and negative spiral feeding ribs to make wood chips flow back and forth and dry air; and a wood chip rod is formed by heating and extruding. The carbonized heating supply system also includes a plurality of cellar-type kiln bodies distributed in a matrix pattern, and a pre-burning heat-conducting tunnel is arranged between the two rows of kiln bodies. The combustible gas in a process of carbonization is affected by a boiler fan, and supplies heat to a boiler in sequence through a pre-combustion heat conduction undergroud tunnel, a total heat conduction underground tunnel, a diverter gate, and a heat supplying pipeline. Under the premise of low cost, relatively good insulation effect and airtight effect are achieved; energy consumption is greatly reduced; quality of charcoal is greatly improved; environmental pollution is eliminated, and at the same time, the instant utilization ofcarbonized gas is safely and conveniently realized; and the scale of the system is convenient for flexible adjustment.
