Product Description
Coal-based Columnar Activated Carbons (CCACs) for adsorption of benzene were prepared using a factorial experiment method. The CCACs prepared were characterized, and their adsorption capacities toward benzene were measured in a differential fixed-bed reactor. Besides, through a statistical method, the importance degree of preparation variables was studied, and the effects of preparation variables on benzene adsorption capacities of the CCACs were fully evaluated. It was found that pore structure of CCACs prepared was beneficial for benzene adsorption, but preparation variable in the process has little effect on the surface chemistry of CCACs prepared. Based on statistic analysis, it was revealed that among the four process variables studied for the sorbent prepared in this work, the activation temperature was found to be the most significant one for benzene adsorption capacity, next ones are the activation time and the amount of KOH, and the last one is the flow rate of water vapor and their optimal levels were 950 °C, 3.0 h, 2.5 % and 1.25 mL/g/h respectively.
Coal-based columnar activated carbon 1.5mm: refined through grinding-kneading-forming- carbonization and steam activation in SLEP furnace. Ultra-low ash, clean and dust-free, strong adsorption capacity, high mechanical strength, well-developed pores and other advantages. Widely used in tap water, drinking water filtration and impurity removal, air purifiers, carbon bags, gas mask protection, etc.

To improve the utilization value of coal resources and optimize the production process of coal-based activated carbon, an orthogonal experiment was designed to study the comprehensive effects of the carbonization temperature, heating rate, activation time and activator type on the specific surface area and iodine value of activated carbon prepared by physical activation, as well as the surface chemical and crystal properties. The results showed that large amounts of C-H and oxygen functional groups from the raw materials were lost in the process of preparing the activated carbon, and CaCO3 generated CaS through a two-step reaction. The raw materials were nonporous or macroporous materials, while the activated carbon developed a microporous structure. The same optimal working conditions were obtained when the iodine value and the specific surface area were used as the optimization target, as follows: 800 °C for carbonization, 10 °C/min for heating rate, 75 min for activation time, and steam + CO2 as the activator. Finally, activated carbon was prepared under the optimal experimental conditions. The results showed that this activated carbon had the highest specific surface area and iodine value. In addition, the iodine value had a good linear relationship with the specific surface area.
