正交实验研究硝酸改性对活性焦表面性质及脱硫性能的影响
Influence of nitric acid modified activated coke on its surface properties and desulphurization performance by orthogonal test
摘要
Abstract
An activated coke was modified by HNO3. The influences of HNO3 concentration, activation temperature, activation time and calcination temperature on surface properties the activated coke were investigated by orthogonal experiments. The SO2 adsorption capacities of the modified activated coke were examined in a fixed bed reactor. The surface acidity-basicity, specific surface area and pore structure coke were characterized by acid-base titration, N2 adsorption, iodine adsorption value and Fourier transform infrared spectrometry, respectively. The results show that HNO3 modification raises the specific surface area and surface basicity of the activated coke. Calcination improves the surface basicity. HNO3 modification obviously enhances the desulfurization performance of the activated coke.关键词
