Preparation of Highly Effective Carbon Adsorbents Based on High-Moor Peat from the European North of Russia
The active coals obtained from high-moor peat of the European North of Russia by thermochemical activation with NaOH and various types of pre-treatment (debituminization and pre-pyrolysis) were studied. Based on the results of the low-temperature adsorption of nitrogen, the resulting active coals belonged to adsorbents whose structure was dominated by micropores. The specific surface area of coal pores reached 2330 m2/g, and the total pore volume was 1.44 cm3/g. The introduction of the stage of pre-pyrolysis made it possible to increase significantly the yield of active coals. This increase was 28 or 97% for the initial peat or debituminized samples, respectively; moreover, the sorption characteristics were significantly improved. It has been shown that weakly decomposed high-moor peat of the European North of Russia can be used as a raw material for the production of high-efficiency carbon microporous adsorbents.
期刊介绍:
The journal publishes theoretical and applied articles on the chemistry and physics of solid fuels and carbonaceous materials. It addresses the composition, structure, and properties of solid fuels. The aim of the published articles is to demonstrate how novel discoveries, developments, and theories may be used in improved analysis and design of new types of fuels, chemicals, and by-products. The journal is particularly concerned with technological aspects of various chemical conversion processes and includes papers related to geochemistry, petrology and systematization of fossil fuels, their beneficiation and preparation for processing, the processes themselves, and the ultimate recovery of the liquid or gaseous end products.
