The desulfurized activated carbon is made of activated carbon fiber which is stable in chemical and physical properties and has good conductivity, and KOH is used as an electrolyte to develop a carbon-based electric double layer capacitor. The effects of vacuum degree, KOH concentration, electrode composition and thickness on the performance of electric double layer capacitors were investigated. The process conditions of electric double layer capacitors were optimized by orthogonal experiment. The results show that a high vacuum, high concentration electrolyte helps to increase the capacitance. 40% KOH solution as electrolyte, electrode composition is ACF: graphite: polytetrafluoroethylene = 1.6:0.4:1, the optimum electrode condition of single electrode sheet is 0.10g, and the obtained de-sulfur activated carbon fiber in electric double layer capacitor The specific capacitance can reach 152.81F / g.
The micropores of the desulfurized activated carbon are different from the activated carbon products currently on the market, and the adsorption performance is also superior to the existing products. The micropores are arranged according to irregular rules, and the uniformity coefficient, specific surface area and iodine adsorption value of the micropores are higher than those of the existing desulfurized activated carbon products. According to its pore diameter, it is divided into: large pores, ie, r>20knm; filter pores, 150nm>r>20knm; micropores, r<150nm; ultramicroporous, r<50nm. The most critical parameter for the adsorption of activated carbon from Yiyang desulfurization is determined by micropores and ultrafines. The micropores and ultramicropores of Yiyang series activated carbon reach more than 96% of the total pore size.
Therefore, Yiyang desulfurization activated carbon ultra-microporous series products are more suitable for adsorption and filtration of fine particles and fine molecules. Ultra-microporous series of activated carbon is more suitable for petrochemical, chemical, Qybknowec food environmental protection and other high-demand industries. Desulfurization activated carbon is named by the shape of activated carbon. According to its material, it can be divided into coal-based granular activated carbon and fruit-shell granular activated carbon. Generally, the shell-shell granular activated carbon has coconut shell granular carbon, apricot shell activated carbon, peach shell activated carbon, etc. Qybknowec The granular granular activated carbon has a relatively large particle size, and 0608 is processed into activated carbon by coking activation treatment of large coal. The coconut shell granular activated carbon has a slightly larger particle size and is irregular in particle size. Mm or mesh to measure the particle size of granular activated carbon.

The pore size distribution of desulfurization activated carbon is mainly composed of mesopores and submicropores. It is mainly suitable for the removal of various sulfides in the gas phase. It has high activity, large sulfur capacity, high desulfurization efficiency, good mechanical strength, low resistance, easy regeneration, high pressure. It is not easy to be broken under high temperature and water immersion. This product is mainly used in various gas, coke oven gas, flue gas, tunnel gas, natural gas and other industries, domestic fuel gas, raw material gas in the removal of various sulfides.
When the oxygen content and hydrogen sulfide content are more than 2 times, it has a unique and efficient removal and purification effect on hydrogen sulfide in the gas. It can be repeatedly regenerated and can recover high-purity elemental sulfur during regeneration. Desulfurization activated carbon application process conditions requirements 1.
