Embodiment 1

[0034] 10 g of mango core powder was placed in a tube furnace, the nitrogen atmosphere was turned on, the nitrogen gas flow rate was 30 mL / min, and then the temperature was raised to 300 °C for 2 h at a heating rate of 10 °C / min. After the carbonization is completed, take it out after cooling in the tube furnace, wash it with distilled water until it is neutral, filter and dry it to constant weight, grind it

experiment example 2

[0036] 10 g of mango core chips were placed in a tube furnace, the nitrogen atmosphere was turned on, and the nitrogen gas flow rate was 30 mL / min, and then the temperature was raised to 400 °C for 2 h at a heating rate of 10 °C / min. After the carbonization is completed, take it out after cooling in the tube furnace, wash it with distilled water to neutrality, then filter and dry it to constant weight, grind it through a 100-mesh sieve, dry it and store it for later use, that is, the mango kernel biochar is obtained. The yield of biochar is 35.42%.

Embodiment 3

[0038] 10 g of mango core chips were placed in a tube furnace, the nitrogen atmosphere was turned on, and the nitrogen gas flow rate was 30 mL / min, and then the temperature was raised to 500 °C for 2 h at a heating rate of 10 °C / min. After the carbonization is completed, take it out after cooling in the tube furnace, wash it with distilled water to neutrality, then filter and dry it to constant weight, grind it through a 100-mesh sieve, dry it and store it for later use, that is, the mango kernel biochar is obtained. The yield of biochar is 31.55%.

Abstract

The invention discloses a method for preparing biochar from waste mango seeds, and belongs to the technical field of biochar preparation. According to the method, a large number of waste mango seeds generated by rotting mangoes in the mango processing process and orchards or farmer markets are used as basic substances, mango seed powder is obtained after cleaning, drying and smashing, then pyrolysis is conducted under the protection of nitrogen, and the mango seed charcoal product is obtained. Examples prove that the raw materials are easy to obtain, the preparation method is simple, the production cost is low, the efficiency is high, fruit waste is recycled, waste utilization is achieved, resources are saved, high-additional-value resource utilization of the mango seeds is effectively achieved, and the prepared charcoal is environmentally friendly and safe and has good large-scale production prospects. Moreover, the problem of environmental pollution can be effectively reduced.

Description

technical field [0001] The invention belongs to the field of biomass resource utilization, and in particular relates to a preparation method of biochar. Background technique [0002] The use of biomass such as agricultural and industrial organic waste to prepare low-cost environmentally friendly materials is not only conducive to the rational management of waste, but also can effectively reduce the environmental pollution caused by it, which is of great significance, especially in the current serious pollution, environmental quality decline and In the context of resource constraints, there is an urgent need to develop inexpensive, sustainable and effective environmentally friendly materials. [0003] Biochar refers to an organic substance rich in stable carbon obtained by high-temperature pyrolysis of biomass under anaerobic or anoxic conditions. Biochar can be prepared from industrial and agricultural waste. It can be used not only as high-quality energy, soil improver, bu...
