Abstract
The invention discloses a recycling method of nutshells. The recycling method comprises the following steps: cleanly washing the nutshells; drying and crushing the nutshells; sieving by a molecular sieve to obtain powder; adding rosin and uniformly mixing; conveying the mixture into a carbonization furnace; heating the mixture to 650-750 DEG C at a temperature rising speed of 5 DEG C/minute-8 DEG C/minute; carbonizing for 1-1.5 hours; cooling the mixture to 300-400 DEG C at a cooling speed of 10 DEG C/minute-15 DEG C/minute; carbonizing for 0.5-0.8 hour; and cooling to obtain amorphous particle active carbon. The active carbon is prepared by taking the waste nutshells as the raw material; a production method is simple and feasible, and comprehensive utilization of resources is realized; wastes are changed into valuable things; and the prepared active carbon has good adsorption performance and can be widely applied to the fields of chemical engineering, food, environment protection, electric power and the like.
Description
Technical field
The present invention relates to reusing of energy source technical field, a kind of regeneration method of shuck.
Background technology
Nut because of its kernel possessed abundant nutritional labeling, and have the titles such as " long-lived fruit ", " anticancer fruit ", " peanut ".Containing in daily life, after people eat kernel, will abandon or burn by shuck.According to research reports, shuck is a kind of biomass resource rich in materials such as lignin, cellulose, hemicelluloses, if it directly being abandoned or burning, necessarily causes the significant wastage of resource.Therefore, strengthen the comprehensive utilization to walnut shell, it is to avoid the waste of walnut shell resource, produce the product that added value is high, be possible not only to effectively process solid waste, and can turn waste into wealth, improve income.
Summary of the invention
It is an object of the invention to provide a kind of regeneration method of shuck, the problem that the regeneration method of this shuck can solve the shuck wasting of resources.
In order to solve the problems referred to above, the technical solution used in the present invention is:
The regeneration method of this shuck comprises the following steps:
A, shuck is cleaned up, dry, pulverize, cross 50 mesh～100 mesh molecular sieves, obtain nut shell powder；
B, in described nut shell powder add Colophonium, mix homogeneously, proceed to retort, with 5 DEG C/min～the programming rate of 8 DEG C/min, be heated to 650 DEG C～750 DEG C, carbonization 1 hour～1.5 hours；
C, with 10 DEG C/min～the cooling rate of 15 DEG C/min, be cooled to 300 DEG C～400 DEG C, carbonization 0.5 hour～0.8 hour, cooling obtain indefinite form granular active carbon.
In technique scheme, more specifically scheme is it may also is that described shuck is selected from one or more in melon seed cases, walnut shell, Semen Pini shell, hazelnut shell.
Owing to have employed technique scheme, the present invention compared with prior art has the advantages that
The present invention prepares activated carbon with discarded shuck for raw material, and manufacture method is simple, it is achieved that the comprehensive utilization of resource, turns waste into wealth, and prepared activated carbon adsorption performance is good, it is possible to be widely used in the fields such as chemical industry, food, environmental protection, electric power.
