Deep cleaning power and adsorption of activated carbon

Deep 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.Activated carbon treatment process is the use of adsorption method to remove odor, some ions and difficult to biodegradable organic pollutants.In the process of adsorption, the specific surface area of activated carbon plays a major role.At the same time, the solubility of the adsorbed substance in the solvent also directly affects the adsorption speed.In addition, pH, temperature changes and the degree of dispersion of the adsorbed substances also have certain effects on the adsorption rate.Principle of activated carbon adsorptionhttps://www.yrdcarbon.com/products/
[activated carbon is a kind of very small granular has a large surface area, and more tiny holes in the granular - capillary. The capillary has very strong adsorption capacity, due to the granular surface area is large, so a good contact with with gas (impurities). When these gases (impurities) encounter capillary by adsorption, purification effect. Activated carbon surface area of the study is very important, only the BET specific surface area detecting data of active carbon method detected result is reliable, domestic at present there are many instruments can only make direct comparison method of detection,https://www.yrdcarbon.com/news/coconut-shell-activated-carbon-for-gold-recovery.html
