In this paper, the process conditions and plasticizing mechanism of granular activated carbon prepared by phosphoric acid were studied, which provided scientific data and theoretical basis for the preparation of high strength granular activated carbon.coconut shell activated carbon manufacturers Fir chip as the raw materials, H - POs as activator, using single factor analysis and orthogonal experimental design method, this paper discusses the influence granular activated carbon pore structure and the iodine adsorption value, methylene blue and strength of various preparation factors, determine the optimum process conditions of preparation of granular activated carbon phosphoric acid, phosphoric acid concentration is 70%, dipping 180%, kneading temperature is 170 ℃, for 60 min kneading time, activation temperature is 350 ℃, the activation time of 210 min. The iodine adsorption value, methylene blue adsorption value, strength and BET specific surface area of GAC were 1020.04mGG, 225mg/g, 88.73% and 1486.48m2/g respectively. The experimental results show that the impregnation ratio and carbon activation temperature have great effects on the adsorption performance of GAC, while the kneading temperature and impregnation ratio have great effects on the strength of GAC. Because the strength of GAC decreases with the increase of impregnation ratio, and the decrease range is large, so the preparation of GAC with compound activator is proposed. The results show that the composite activator can reduce the impregnation ratio of phosphoric acid to wood chips and improve the strength of granular activated carbon. At the same time, the composite activator can improve the adsorption performance of GAC.www.chinactivecarbon.com Therefore, granular activated carbon with good adsorption performance and high strength can be prepared by this method.The complete set of equipment not only solves the industrial method of composite graphene liquid phase method to the activated carbon material used for supercapacitor, but also can activate the activated carbon material twice at room temperature. The complete set of equipment meets the requirements of cleaner production. Chapter 2: The quality of graphene prepared by this project is guaranteed. Self-made graphene has a high single-layer rate (up to 99%), fewer defects, and can be dried for a long time.The results show that the adsorption isotherms of Zn2' and Cd by modified activated carbon are in good agreement with the Langmuir and Freundlich adsorption models. By fitting the kinetic equation of Zn2 adsorption with modified activated carbon, it was found that the first 30min of the adsorption reaction was in line with the Lagergren quasi-first-order reaction, and the second order reaction was in line with the latter. The adsorption of Cd by modified activated carbon was a Lagergren quasi-first order reaction in the first 20 minutes. The reaction after adsorption for 20min belongs to the Lagergren quasi-second order reaction.

Make the industrialized application of graphene possible, promote the advancement of high-tech materials, and promote the development of the industry.Performance and its influencing factors. The results show that the increase of adsorption time, pH and the amount of adsorbent will improve the adsorption effect of the modified activated carbon. Based on the experimental data of adsorption of Zn2' and Cd by modified activated carbon and the adsorption principle, the mechanism and kinetic law of adsorption of heavy metal ions by modified activated carbon were studied. Chapter 3 Activated carbon materials for graphene-modified supercapacitors have good technical properties:The surface functional group structure and specific surface area of the modified GAC were changed, and the changes of the surface functional group structure and specific surface area of the activated carbon prepared by different modification methods were different. The specific surface area of activated carbon modified by nitric acid increased from 925.45m'lg to 960.52m2/g, and the number of acid functional groups (carboxyl group, phenolic hydroxyl group) increased from 0.23 mmol/g to 0.36 mmol/g, while the number of acid functional groups and specific surface area of activated carbon modified by reduction decreased.Long cycle life, graphene modified supercapacitors due to its energy storage process does not react, the energy storage process is reversible, no "memory effect", can be repeated charge and discharge hundreds of thousands of times, 500 times that of lithium ion batteries, nickel-metal hydride and nickel cadmium battery is 1000 times, if the ultracapacitors charge-discharge 20 times a day, continuous use of up to 68 yearstemperature and pressure of carbonization furnace. The carbonization process of carbonization furnace is a complex chemical reaction process, which has the characteristics of multivariable coupling, nonlinear, time delay and so on. It is difficult to establish accurate mathematical model for furnace outlet temperature and furnace tail pressure, and it is difficult to realize it by means of general control process. Through the comparison and analysis of the fuzzy PID control and the parameter self-adjusting fuzzy PID control simulation, the final determination of the parameter self-adjusting fuzzy PID control algorithm, the blower and induced draft fan speed adjustment, the simulation shows that the control effect is good, has a certain application value.

Chapter 3 Activated carbon materials for graphene-modified supercapacitors have good technical properties:bulk powdered activated charcoal Long cycle life, graphene modified supercapacitors due to its energy storage process does not react, the energy storage process is reversible, no "memory effect", can be repeated charge and discharge hundreds of thoDeep desulfurization of transportation fuels is receiving increasing attention in theresearch community worldwide due to increasingly stringent regulations and fuelspecifications in many countries for environmental protection purpose. The traditionalhydrodesulfurization process (HDS) is highly efficient in removing thiols and sulfides, but itis less effective for thiophenes and thiophene derivatives. Ultra-deep desulfurization isbecoming even more formidable challenge for HDS with the decreasing lower sulfur in fuels.Therefore, non-hydrodesulfurization technique of liquid fuels has caused intensive concernsfor ultra-deep desulfurization. Recently, the adsorption desulfurization technique and catalyticoxidation-adsorption desulfurization technique have drawn much attention at home andabroad due to its mild reaction condition,low production cost and little environmentalpollutioz. This thesis focuses on the researches of application of activated carbon fiber inadsorption and oxidation-adsorption removal of thiophenic sulfur compounds from oils.usands of times, 500 times that of lithium ion batteries, nickel-metal hydride and nickel cadmium battery is 1000 times, if the ultracapacitors charge-discharge 20 times a day, continuous use of up to 68 years
