Blends consisting of a high volatile bituminous coal, biomass, and binder that were used in the preparation of briquettes were analyzed in order to select the best components from the viewpoint of their influence on the coal’s thermoplastic properties. The raw materials were studied by means of thermogravimetry, high-temperature rheometry, high-temperature proton nuclear magnetic resonance (¹H NMR), and Fourier transform infrared (FTIR) spectroscopy. In addition, the fluidity of the blends was determined with the standard Gieseler plastometer test method (ASTM D 2639-74). Various parameters derived from these different techniques were used to explain the effects of biomass and binder on the fluidity of the blends with coal. It was found that the deleterious effect of biomass was mainly related to its physical properties, whereas the effect of the binder was controlled by its chemical composition. Coal tar, coal tar sludge, pine sawdust, and a biocoal derived from hydrothermally treated waste biomass obtained from pruning were the best materials for the preparation of briquettes for cokemaking.

生物质和粘结剂选择对焦煤压块制备的重要性。它们对煤热塑性的影响

分析了用于团块制备的由高挥发性烟煤，生物质和粘结剂组成的混合物，以便从它们对煤的热塑性特性的影响角度出发，选择最佳的组分。通过热重法，高温流变法，高温质子核磁共振对原料进行了研究（¹1 H NMR）和傅立叶变换红外（FTIR）光谱。另外，共混物的流动性通过标准的吉塞勒塑性仪测试方法（ASTM D 2639-74）确定。来自这些不同技术的各种参数被用来解释生物量和粘结剂对与煤共混物流动性的影响。发现生物质的有害作用主要与其物理性质有关，而粘合剂的作用由其化学组成控制。煤焦油，煤焦油污泥，松木屑和从水热处理后的修剪后得到的废生物质中提取的生物煤是制备制焦煤饼的最佳材料。
