Problems solved by technology

However, due to various conditions, such as poor color, strong bloody smell, and poor palatability, the utilization rate of pig blood in my country is not high, and a few are used to make "blood tofu", but the hygienic conditions are difficult to control
At present, the products developed using pig blood resources in my country are relatively monotonous. Except for a small part that is processed into blood meal or fermented blood meal as a feed additive and used in biochemical pharmaceuticals to produce heme, superoxide dismutase, and peptone, a considerable part It is dumped into the ditch as waste, which not only causes huge waste, but also pollutes the environment

preparation example Construction

[0037] The application provides a preparation method of activated carbon, which comprises:

[0038] 1. Preparation of carbon source materials

[0039] Carbon source materials include fish scales and / or animal blood.

[0040] It should be noted that the carbon source material may be all fish scales, or all animal blood, or a mixture of fish scales and animal blood.

[0041] Wherein, animal blood includes blood meal.

[0042] Blood meal is a kind of unconventional animal-derived feed. It is made by coagulating animal blood into clots, steaming at high temperature, pressing to remove juice, drying in the sun, and then crushing. Blood meal is a processed product of animal blood.

[0043] Moreover, the blood meal is processed animal blood, in which the water content is less, generally within 12%, but the crude protein content is increased, above 60%.

[0044] If the carbon source material is animal blood, the animal blood needs to be prepared into blood powder or other solid bl...

Embodiment 1

[0076] The embodiment of the present application provides an activated carbon and a preparation method thereof.

[0077] 1. Preparation of carbon source materials

[0078] The fish scales were cleaned and dried at 100 °C for 10 h.

[0079] 2. Activation

[0080] Mix 10g of washed and dried fish scales with 20g of potassium hydroxide solution with a concentration of 13.5mol / L, let it stand for 5 hours, put the rested material into a muffle furnace, and heat up to 300°C at 20°C / min for activation After cooling to room temperature for 60 minutes, take out the activated material.

[0081] 3. Post-processing

[0082] Wash the cooled activated material 5 times with deionized water, filter to obtain a solid, dry at 110°C for 10 hours, take out, grind and sieve to obtain activated carbon.

Embodiment 2

[0084] The embodiment of the present application provides an activated carbon and a preparation method thereof.

[0085] 1. Preparation of carbon source materials

[0086] The fish scales were cleaned and dried at 100 °C for 10 h.

[0087] 2. Activation

[0088] Mix 10g of washed and dried fish scales with 20g of potassium hydroxide solution with a concentration of 13.5mol / L, let it stand for 5 hours, put the rested material into a muffle furnace, and heat up to 400°C at 20°C / min for activation After cooling to room temperature for 60 minutes, take out the activated material.

[0089] 3. Post-processing

[0090] Wash the cooled activated material 5 times with deionized water, filter to obtain a solid, dry at 110°C for 10 hours, take out, grind and sieve to obtain activated carbon.

Abstract

The invention discloses an activated carbon and a preparation method thereof, and belongs to the technical field of waste utilization. The preparation method of the activated carbon comprises the following steps: uniformly mixing a carbon source material and an activating agent, standing, and activating the carbon source material treated through standing at 300-600 DEG C for 30-90min. The carbon source material comprises fish scales and / or animal blood; the activating agent includes a potassium hydroxide solution. The activated carbon is prepared by mixing waste fish scales and / or animal bloodwith the activating agent and activating at 300-600 DEG C. Waste is changed into valuables, waste utilization rate is increased, meanwhile, the activation temperature is low, and effective energy saving can be achieved.

Description

technical field [0001] The present application relates to the technical field of waste utilization, in particular to an activated carbon and a preparation method thereof. Background technique [0002] A large amount of waste is produced in the fishery processing process, and fish scales occupy a large part of the waste. Only a small part of fish scales is roughly processed as low-value fish meal for the feed industry or used to extract collagen and gelatin, and other fish scales are usually directly discarded, causing environmental pollution and waste of resources. [0003] Animal blood resources are underutilized. Take pig blood as an example: pig blood is rich in various nutrients and active ingredients. It is a by-product of the food industry that is high in protein, low in fat, low in sugar and rich in trace elements. At present, my country has the largest number of pigs slaughtered in the world. The annual slaughter of pigs is about 600 million, and each pig produces a...
