The composition and structure of coal from wuchang, tuha and zhundong coalfields in xinjiang can be determined by elemical analysis, photoelectron spectroscopy, plasma emission spectrum, infrared spectrum and high resolution solid nuclear magnetic field, and the coal suitable for xinjiang coal-based yrdcarbon activated carbon production can be screened out.
Taking the screened coal as raw material, through the coal preparation, molding, carbonization, activation, product processing and other five technological processes, and using catalytic activation method to prepare coal-based activated carbon.
Comprehensive study all the related factors in the process of production of activated carbon products pore structure, specific surface area, surface functional groups, the influence of especially the kinds and dosage of catalyst and activator, carbonization temperature, activation temperature and activation time, activation atmosphere, ash content, coal particle size, Activated carbon has a microcrystalline structure, activated charcoal powder wholesale the microcrystalline arrangement is completely irregular, crystal has micropores, transition pores, macropores, so that it has a large inner surface, specific surface area of 500~1700m2/g.carbonization and activation conditions, such as optimizing the preparation technology of high quality coal based activated carbon, can be prepared high quality activated carbon products.* 恋爱 ** 恋爱 ** 恋爱 *
