为了在炼焦过程中有效利用低阶煤和生物质，通过溶解法制备了超煤（HPC），并研究了其作为炼焦过程中一种添加组分的性能。使用I型转鼓测试仪和万能试验机测试了焦炭的冷强度；通过热重分析（TG）、X射线衍射（XRD）和傅里叶变换红外光谱（FT - IR）分析检测了超煤的碳结构。结果表明，与原煤相比，超煤的热塑性和焦炭冷强度有所提高。焦炭的冷强度与超煤的有序度之间呈正线性关系。随着生物质含量的增加，超煤的有序度大幅降低，导致焦炭冷强度下降。当生物质含量为20%时，粘结指数（G）、转鼓强度和抗压强度分别达到最大值95.21%、83%和7.13 MPa。此外，还提出了超煤的粘结机理。
To effectively utilize low-rank coal and biomass in the coking process, through the dissolution method, hypercoalb(HPC) was produced, and its performance as an additional component in the coking process was also investigated. The cold strength of coke was tested using an I-type tumble tester and a universal testing machine; the carbon structure of the HPCs was examined via thermogravimetry (TG), X-ray diffraction (XRD), and Fourier transform infrared spectrometry (FT-IR) analyses. The results revealed that the thermoplastic properties of HPCs and the coke cold strength increased compared to raw coal. There is a positive linear relationship between the cold strength of coke and the order degree of the HPCs. As the biomass amount increased,.the order degree of the HPCs greatly decreased, resulting in a decrease in the coke cold strength. When the amount of biomass was 20%, the caking index (G), drum strength, and compressive strength achieved maximum values of 95.21%, 83%, and 7.13 MPa, respectively. In addition, a caking mechanism of the HPCs is proposed.
