在本次调查中，来自印度东北地区（NER）的低阶煤样品被球化，然后在蜂箱式焦炉中碳化以得到有效利用。不同类型的粘合剂（例如羧甲基纤维素和糖蜜）和添加剂（石灰）用于制备结核，以分别提高其强度并减少含硫气体的排放。测定煤样和碳化结核的理化性质和总热值。碳化结核的物理强度在376.81-448.84 N的范围内，被发现适合其运输和处理目的。对碳化球进行了热分析（热重分析-差热分析；TGA-DTA）、傅里叶变换红外（FTIR）光谱分析和扫描电子显微镜（SEM）分析，表明碳化球在球化和碳化过程中燃烧、官能团转变及其结构变化的反应活性较低。碳化结核适合在水泥制造和其他家庭用途中用作焦炭。 (C) 2014 Elsevier Ltd. 保留所有权利。
In the present investigation, the low rank coal samples from North Eastern Region (NER) of India are nodulized and then carbonized in a beehive-type coke oven for their gainful utilization. Different types of binders (e.g. carboxymethyl cellulose and molasses) and an additive (lime) are used to prepare the nodules for increasing their strength and to reduce the emission of sulfur containing gases, respectively. The physicochemical properties and the gross calorific values of the coal samples and carbonized nodules are determined. Physical strength of the carbonized nodules are within the range of 376.81-448.84 N, which are found to be suitable for their transportation and handling purposes. The thermal analysis (Thermogravimetric analysis-Differential thermal analysis; TGA-DTA), Fourier Transform Infra-Red (FTIR) spectroscopic analysis and Scanning Electron Microscopic (SEM) analysis of the carbonized nodules are also performed, which indicate the lower reactivity of the carbonized nodules on combustion, transformation of functional groups and their structural changes during nodulization and carbonization processes. The carbonized nodules are suitable for using as a coke-breeze in cement manufacturing and other domestic purposes. (C) 2014 Elsevier Ltd. All rights reserved.
