Description
Technical Field
The invention relates to a production method of activated carbon, in particular to a production method of coal-based molded activated carbon with integrated carbon activation, belonging to the technical field of activated carbon production.
Background
The traditional production process of the coal-based formed activated carbon mainly comprises the following steps:
grinding: grinding raw material coal into pulverized coal with 200 meshes of passing rate more than or equal to 90%;
kneading and forming: adding heated coal tar or pitch which accounts for 15-38% of the weight of the coal dust into the coal dust, kneading and forming, naturally air-drying the formed coal tar or pitch, cooling and solidifying, wherein the formed coal tar or pitch has initial strength and contains volatile matters in the coal dust, and the volatile matters of the formed coal tar reach about 20% -50%;
③ carbonizing: carbonizing the molded coal briquette, wherein the carbonization temperature is about 450-550 ℃, the raw material coal and coal tar or asphalt used as a binder begin to decompose, fuse and largely volatilize during the temperature rise of the molded coal briquette, the residual part of the volatilized coal tar or asphalt is less than 10% of the original weight, and the residual substances of the coal tar or the asphalt in the molded coal briquette form a framework to keep the strength of the molded active carbon. After carbonization, the molded coal becomes carbonized material with strength, and is cooled and discharged for standby;
activation: the activation reaction is a chemical reaction of carbon and water vapor at a high temperature of 850 ℃, i.e., C and H2O production of CO and H at high temperatures2CO and H2The combustible gas is used for supplementing heat required by activation reaction, the activation furnace can realize self-heating by means of the volatile matter of the carbonized material and the combustion of self carbon, and the activated carbon with different technical indexes can be produced by adjusting the parameters of the temperature, the water vapor, the activation time and the like of the activation furnace.
In order to enable a finished product to have strength and increase the fluidity of raw material coal so as to enable the finished product to be molded, coal tar or pitch is added as a binder in the conventional process, but most of the coal tar or pitch is combusted after volatilization in the carbonization process, only a small part of the coal tar or pitch forms a carbon skeleton and has the function of maintaining the strength, and the conventional process needs a separate carbonization step to volatilize the coal tar or pitch, so that if the coal tar or pitch is directly put into a furnace for carbonization and activation integration, the carbon is adhered and agglomerated in the furnace, and the equipment cannot operate. The coal tar or the pitch has high price, so that the production cost is high; meanwhile, the coal tar or the pitch is added as a binder, so that the problem of serious pollution is caused;
at present, a part of the prior art is that bentonite, activated clay, diatomite and other inorganic binders are added into coal or other carbon-containing materials to replace coal tar or pitch for use, and the problems exist that the inorganic binders are poor in cross-linking property with the coal or the carbon-containing materials, the addition proportion is high, the carbon content of raw materials is reduced, the main components of the inorganic binders are not changed after high temperature is met in carbonization and activation, the proportion of the inorganic binders is reduced after volatilization and production consumption after the coal or the carbon materials are carbonized and activated, the carbon content of produced products is low, and the index is low; and organic binders such as phenolic resin and the like are added to replace coal tar or pitch for use, and a carbon skeleton with strength can be formed through carbonization and activation, but the carbon skeleton formed by the organic binders has low content of substances, high price and high use cost, and is rarely adopted in general actual production.

kneading and forming: adding an auxiliary agent and water into the pulverized coal for kneading to obtain molded coal, wherein the auxiliary agent is one or more of hydroxyethyl cellulose, carboxymethyl cellulose, polyacrylamide, phosphate and sulfate, accounts for 1-3% of the total amount of the mixed pulverized coal, and the water accounts for 15-25% of the total amount of the mixed pulverized coal;
thirdly, air drying: naturally air drying or low-temperature drying the molded coal until the water content is lower than 3 percent;
fourthly, carbon activation integration: putting the air-dried molded coal into a carbon activation integrated furnace for carbon activation, setting the feeding temperature to be 100-150 ℃, controlling the oxygen content after the furnace is put to ensure that the temperature rising rate of the molded coal is 12-15 ℃/min, reaching the activation reaction condition when the temperature rises to 800 ℃, starting to introduce steam for activation, wherein the steam pressure is more than or equal to 3.0Mpa, the steam reacts with the molded coal and the carbon in the volatile matter of the molded coal, starting the activation reaction, adjusting the oxygen content and the steam quantity to keep the activation temperature at 850-1000 ℃, continuously introducing the steam at the temperature, continuing the activation reaction, and discharging the molded coal for 1-6h to obtain the finished product.
The main coal is easy to activate, and the pores are easy to open under the activation condition, and the main coal is one or more of anthracite, lean coal, long flame coal, gas coal, non-caking coal, weakly caking coal, lignite and semi coke;
