摘要

通过使用 NaOH 进行热化学活化以及各种类型的预处理(脱铝和预热解),研究了从俄罗斯欧洲北部高荒漠泥炭中获得的活性煤炭。根据低温吸附氮气的结果,得到的活性煤属于结构以微孔为主的吸附剂。煤孔的比表面积达到 2330 m2/g,总孔容积为 1.44 cm3/g。引入预热解阶段可显著提高活性煤的产量。对于初始泥炭或脱硝样品,产量分别提高了 28% 或 97%;此外,吸附特性也得到了显著改善。研究表明,俄罗斯欧洲北部的弱分解高荒漠泥炭可用作生产高效微孔碳吸附剂的原料。

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.
