Abstract

The paper presents the results of a physicochemical analysis of coke sample from “Euromet” LLP (Karaganda, Kazakhstan), which is a carbonaceous material with high carbon content, the absence of volatiles matter and low ash content. Carbon sorbents were obtained from low-value fractions of carbonized materials of the Karaganda region coke production by the steam-gas activation. An important advantage of using screenings (coke breeze class 0-10 mm, which was crushed and fractionated to a particle size of 2-5 mm.) is the exclusion of the energy-intensive carbonization stage from the technological process, which releases a large amount of environmentally harmful substances (phenols, cresols, gaseous emissions etc.). The optimal conditions for obtaining a sorbent from low-value coke breeze are a temperature of 850 °C and an activation time of 2 hours. The physicochemical properties (ash content, bulk density, sorption capacity for iodine and methylene blue, total pore volume for water) of carbon sorbents were determined
从“Euromet”LLP焦炭微风中获得碳吸附剂
本文介绍了“Euromet”LLP (Karaganda, Kazakhstan)焦炭样品的理化分析结果,该焦炭样品是一种含碳量高、无挥发物、灰分含量低的含碳材料。采用蒸汽-气活化法,从卡拉干达地区焦炭生产的低价值焦化物料中提取碳吸附剂。使用筛分(焦炭级0-10毫米,粉碎和分馏到2-5毫米的粒度)的一个重要优点是从工艺过程中排除了能源密集型的碳化阶段,这释放了大量对环境有害的物质(酚类,甲酚,气体排放等)。从低价值焦渣中获得吸附剂的最佳条件是850℃的温度和2小时的活化时间。测定了碳吸附剂的理化性质(灰分含量、容重、对碘和亚甲基蓝的吸附能力、对水的总孔隙体积)
