Abstract

Additive water is usually needed to preserve 9–11% moisture content of blended coal in the stamp-charging coking process, which in fact is unfavorable for coking property. An insight into the improvement of coking property of coal blends with much low-rank coal (long flame coal SFC, lignite HLH) by regulating additive water was proposed in terms of its effects on the metaplast fluidity and the particle agglomeration behavior. The results indicate that the cohesiveness of gas coals (GC) can be properly enhanced by adding water. The restrictions on the condensation of aromatic structures and the break-up of –CH2– structure and the development of the polyhydroxy groups in aromatic structures are favorable to increase the fluidity of metaplast after adding water, as demonstrated by the optical texture and FTIR analysis of the semicoke (450 °C). The great difference in the hydrophilic properties for various rank coals leads to the particle agglomeration of gas coal and fat coal (GC and FC), which makes them difficult to mix uniformly with SFC after adding water, thus reduces the coking property. A reasonable approach of adding water suggests that H2O and SFC should be well mixed prior to blending with caking coals, which can lead to a uniform particle distribution and a better coking property. This approach promotes the direct and efficient utilization of low-rank coal (especially lignite) by the blending coking with no or less drying and dewatering processes.

Abstract

To produce a qualified gasification-coke by blending a larger proportion of low-rank coal, the effects of blending ratio, particle size distribution, and maceral components on the coke strength were studied, and a new coking mechanism was put forward in terms of the physical texture. The results show that the influence of coal particle size varies with the different cohesiveness of coals. Fat coal (FC) with a smaller size gets a better performance on the coke strength, while a larger size is needed for gas coal (GC), and the optimum size of long flame coal (Shenfu coal, SFC) varied with its blending ratio. SFC and GC should be crushed coarsely (2–3 mm surpasses 40%) to act as the framework with the less external surface in the viscous embedded state. FC should be crushed finely ( M 25 > 90%, CRI > 50%, CSR > 35%) can be obtained by blending >40 wt% SFC with this new coking mechanism.
