Embodiment 1

[0018] Leaves that fall naturally in the field are dried in an oven at 42°C, crushed to 400 mesh with a pulverizer after drying, and dried again at the same temperature for 39 minutes to obtain litter powder, and then take 100kg of phenol and heat it in a water bath at 65°C 12min, when it is completely melted into a liquid state, quickly pour it into the reactor, control the temperature of the reactor at 95°C, add 40kg of litter powder, stir and mix evenly, slowly add 2kg of concentrated nitric acid and 2kg of hydrogen peroxide, and stir for 50min until the liquid becomes into a dark red liquid, then add 4 kg of sodium dodecylbenzenesulfonate, stir, mix and dissolve evenly, stop heating until it becomes a clear black liquid, and finally cool to room temperature, seal and store to obtain the litter liquefaction liquid.

Embodiment 2

[0020] Put the naturally littered leaves in the field into an oven at 51°C for drying, crush them to 350 mesh with a pulverizer after drying, and dry them again at the same temperature for 50 minutes to obtain litter powder, then take 100kg of phenol and heat it in a water bath at 75°C 18min, when it is completely melted into a liquid state, quickly pour it into the reactor, control the temperature of the reactor at 93°C, add 40kg of litter powder, stir and mix evenly, slowly add 2kg of concentrated nitric acid and 2kg of hydrogen peroxide, and stir for 75min until the liquid becomes into a dark red liquid, then add 4 kg of sodium dodecylbenzenesulfonate, stir, mix and dissolve evenly, stop heating until it becomes a clear black liquid, and finally cool to room temperature, seal and store to obtain the litter liquefaction liquid.

Embodiment 3

[0022] Leaves that fall naturally in the field are dried in an oven at 44°C, crushed to 300 mesh with a pulverizer after drying, and baked again at the same temperature for 41 minutes to obtain litter powder, and then take 100kg of phenol and heat it in a water bath at 70°C 14min, when it is completely melted into a liquid state, quickly pour it into the reactor, the temperature of the reactor is controlled at 91°C, add 40kg of litter powder, stir and mix evenly, slowly add 2kg of concentrated nitric acid and 2kg of hydrogen peroxide, and stir for 55min until the liquid becomes into a dark red liquid, then add 4 kg of sodium dodecylbenzenesulfonate, stir, mix and dissolve evenly, stop heating until it becomes a clear black liquid, and finally cool to room temperature, seal and store to obtain the litter liquefaction liquid.

Abstract

The invention discloses a liquefaction method of forest litter, and belongs to the technical field of bioengineering. The liquefaction method is characterized by comprising the following steps: 1) collecting outdoor naturally withering leaves as materials, baking and then crushing, and baking again at the same temperature so as to obtain litter powder; (2) putting phenol into a water bath at 50-80 DEG C to heat for 10-21 minutes; rapidly pouring into a reaction kettle when the phenol is completely fused into liquid, controlling the temperature of the reaction kettle at 85-110 DEG C, and then adding the litter powder; slowly dropwise adding concentrated nitric acid and hydrogen peroxide after evenly stirring and mixing, stirring for 50-75 minutes until the liquid becomes dark red liquid, adding sodium dodecyl benzene sulfonate, stirring, mixing and dissolving uniformly, and stopping heating until the liquid becomes clear black liquid; 3) cooling the liquid to room temperature, so as to obtain litter liquefied liquid. The liquefaction method of the forest litter is low in liquefaction cost, simple and feasible, accurate and reliable, and the forest litter can be effectively liquefied.

Description

technical field [0001] The invention belongs to the technical field of bioengineering, in particular to a method for liquefying forest litter. Background technique [0002] Forest litter refers to the general term for all organic substances produced by biological components in the ecosystem and returned to the surface of the forest as a source of material and energy for decomposers to maintain ecosystem functions. Forest litter is the product of metabolism during the growth and development of forest plants, and plays an important role in the nutrient cycle of forest ecosystems. At present, how to accelerate the decomposition of litter or improve the utilization rate of litter has attracted more and more attention from forest scientists, ecologists and forest management workers. [0003] The liquefaction of biological materials is an effective way to fully tap the potential value of natural raw materials, which has attracted the attention of various countries and scientific ...
