Abstract

The thermokinetic parameters of the thermal decomposition of primary coal tar (PCT) from AO Shubarkol Komir in the Republic of Kazakhstan in the presence of a microsilicate nanocatalyst were experimentally determined. The salts of Group VIII metals (iron, cobalt, and nickel) were preliminarily supported onto the surface of the nanocatalyst. The method of thermogravimetry in an inert atmosphere of nitrogen was applied. The thermokinetic parameters of the decomposition of PCT (activation energy, preexponential factor, and rate constants) found in the absence and presence of the nanocatalyst were calculated using thermogravimetric analysis methods. The experimental results of the kinetics of PCT decomposition can be used to develop a database for the mathematical modeling of the processing of this type of raw materials.

镍、钴和氧化铁负载在微硅酸盐上的催化剂存在下原煤焦油热分解的动力学研究

摘要

在微硅酸盐纳米催化剂存在下，哈萨克斯坦共和国 AO Shubarkol Komir 的原煤焦油 (PCT) 热分解的热动力学参数进行了实验确定。VIII族金属（铁、钴和镍）的盐被初步负载在纳米催化剂的表面上。采用惰性氮气气氛中的热重分析法。使用热重分析方法计算在不存在和存在纳米催化剂的情况下发现的 PCT 分解的热动力学参数（活化能、指前因子和速率常数）。PCT分解动力学的实验结果可用于开发用于此类原材料加工数学建模的数据库。
