Advantages and uses of regeneration material
Because world resources are always a hot topic for mankind, the slogan of saving resources has slowly penetrated into people's hearts, so the awakening of recycled materials is also inevitable, so that people can truly achieve environmental protection and energy conservation through the recycling of resources. The biggest advantage of recycled materials is that the price is definitely cheaper than new materials. Although its overall performance and attributes are not as strong as new materials, we do not need to use materials that have good properties and performance in many products. To make it, it wastes a lot of unnecessary attributes, and the recycled material is different. According to different needs, only a certain aspect of the attribute needs to be processed to produce the corresponding product, so as not to lose resources. . Recycled materials are generally produced by the recycling and reuse of chemical products. Through certain processing methods, various corresponding products are manufactured. Different product requirements have different properties of recycled materials. In this way, recycled materials can be used to manufacture products. Different products because of the world's resources. More and more users use recycled materials, and plastic product manufacturers are increasingly favoring the use of recycled materials.

Application of steam activated carbon in organic waste gas
1. Condensation recovery method: The organic waste gas is directly introduced into the condenser through adsorption, absorption, dissolution and separation, and valuable organic matter can be recovered. This method is suitable for the working conditions of high organic waste gas concentration, low temperature, and small air volume, and requires attachment Refrigeration equipment, mainly used in the pharmaceutical and chemical industries, less used by printing companies 2. Absorption method: Generally, physical absorption is used, that is, the exhaust gas is introduced into the absorption liquid for purification. After the absorption liquid is saturated, it is heated, analyzed, and condensed for recovery; this method is suitable for large-scale, low-temperature, and low-concentration exhaust gas, but heating is required Analysis and recovery device, the equipment is large and the investment is relatively high. Generally, the activated carbon adsorption method is adopted: the exhaust gas is adsorbed by activated carbon. When the adsorption is saturated, the activated carbon is desorbed and regenerated. The exhaust gas is blown off and catalytically burned to convert it into harmless substances. The regenerated activated carbon is continued to be used. When the activated carbon is regenerated to a certain number of times, the adsorption capacity is significantly reduced, and the activated carbon needs to be regenerated or updated. Activated carbon is currently the most used method to treat organic waste gas. It has good adsorption performance for benzene waste gas, but has poor adsorption for hydrocarbon waste gas. The main disadvantage is that the operating cost is high and it is not suitable for the environment with high humidity. However, as far as the current market applications are concerned, the use of activated carbon adsorption is the most commonly used. Activated carbon is mostly used: activated carbon particles and activated carbon fibers. The price of activated carbon particles is relatively cheap, but the effect is lower. In comparison, the price of activated carbon fibers is relatively higher and the effect is better.
Advantages of steam activated carbon
Advantages of activated carbon for water purification 1. It can work continuously for 24 hours without shutting down and backwashing, and it has the characteristics of high efficiency. 2. There is no need for a high-lift and large-flow backwash pump, which means that the operating cost of the activated carbon filter is relatively low. 3. During operation, there are basically no rotating parts except the quartz sand filter material, so the failure rate is relatively low, and a large amount of maintenance costs can also be saved. 4. The activated carbon filter does not require a separate coagulation tank, clarification tank, etc., nor does it require backwash pumps, electric and pneumatic valves and other equipment. The amount of engineering is relatively small, and the one-time investment is relatively small. 5. Small head loss: You have a single filter material and the filter material is cleaned in time, so the head loss will be relatively small. 6. It can withstand a certain concentration of water quality for a long time, and can withstand the impact in a short time and keep the water quality unchanged. 7. The filtered water quality is relatively stable, and the filtering effect is relatively good. The filter material is cleaned in a timely manner, which can ensure high-quality and stable water output, and there is no periodic water quality fluctuation. 8. The unit operation mode adopted by the activated carbon filter is to increase or decrease the number of filters flexibly according to the changes in water volume, which is beneficial for modification and expansion. 9. The traditional three-stage reclaimed water treatment process can be integrated, which can save land and make the appearance more beautiful. Editor's summary: The function of activated carbon for water purification and the advantages of activated carbon for water purification have been introduced here, and I hope it will be helpful to everyone.

What is the carrier of the silica catalyst?
The main advantage is that the chemical properties are relatively stable. It is an acidic oxide and does not react with ordinary acids. It does not interact with halogens, hydrogen halides, sulfuric acid, nitric acid, and perchloric acid other than fluorine and hydrogen fluoride (except for hot concentrated phosphoric acid). If it reacts with the catalyst, it will cause the catalyst to be poisoned. A phenomenon in which the activity and selectivity of the catalyst are significantly reduced or lost due to the trace impurities contained in the reaction raw materials. The essence of the poisoning phenomenon is a certain chemical action of trace impurities and the active center of the catalyst to form inactive species. Secondly, silica has good wear resistance, stable chemical properties, and high melting point. For this reason, using it as the main mineral phase material as the catalyst carrier, its performance is stable. In addition, the treated silicon dioxide has a high specific surface area and strong adsorption, which can increase the catalytic efficiency of the catalyst! In general, the silica carrier has great advantages in terms of catalytic efficiency, catalytic activity, solidity of catalyst loading, service life, and price! Fumed silica (fumed white carbon black) is one of the extremely important high-tech ultrafine inorganic new materials. Because of its small particle size, it has a large specific surface area, strong surface adsorption, large surface energy, high chemical purity, and dispersion. Good performance, heat resistance, electrical resistance and other aspects have specific performance, with its superior stability, reinforcement, thickening and thixotropy, it is especially advantageous in the catalyst carrier.
