Provided by Huixin Water saving Material FactoryPetrochemical activated carbonIt is made from high-density fruit shells as raw materials and refined by physical methods. It is mainly used for decolorization and purification in the petrochemical industry, water treatment projects in the petrochemical industry, and can remove harmful substances from petroleum. It can be used as a catalyst or carrier in the synthetic industry.

Petrochemical activated carbon can be made from various carbonaceous materials, including wood, sawdust, coal, coke, peat, lignin, fruit kernels, hard fruit shells, sucrose pulp, bone, lignite, petroleum residue, etc. Among them, coal and coconut shell have become the most commonly used raw materials for manufacturing activated carbon.
The manufacturing of activated carbon is basically divided into two processes. The first process includes dehydration and carbonization. The raw materials are heated, dried at a temperature of 170 to 600 ℃, and approximately 80% of the original organic matter is carbonized. The second process is to activate the carbonized material, which is achieved by reacting it with an activator such as water vapor and carbon. In the endothermic reaction, a mixed gas composed of CO and H2 is mainly produced, which is used to burn and heat the carbonized material to an appropriate temperature (800 to 1000 ℃) to remove all decomposable substances, thereby producing a developed microporous structure and a huge specific surface area, thus having strong adsorption capacity.
The pores of activated carbon can be divided into three categories based on their pore size. Large pores: radius 1000-1000 mA. Transition pores: radius 20-1000 A. Micro pores: radius -20 A.
Activated carbon made from different raw materials has different pore sizes. Activated carbon made from coconut shells has the smallest pore radius. Wooden activated carbon generally has the largest pore radius, which is used to adsorb larger molecules and is almost exclusively used in the liquid phase. The first type of granular activated carbon used in urban water treatment is made of wood and is called charcoal.Coal based activated carbonThe pore size is between the two.
Petrochemical specific activated carbon is a porous carbonaceous material with highly developed pore structure, making it an excellent adsorbent. The adsorption area per gram of activated carbon is equivalent to eight tennis courts And its adsorption effect is achieved through physical adsorption force and chemical adsorption force In addition to the carbon element, its composition also contains small amounts of hydrogen, nitrogen, oxygen, and ash, and its structure is formed by the stacking of six rings of carbon. Due to the irregular arrangement of six ring carbon, activated carbon has the characteristics of multiple micropores and high surface area.
