Significantly enhances caking index of long‐flame coal under tetralin‐glycerol/H₂ system

For alleviating of the shortage of coking coal resource and efficient cleaning and utilization of low‐rank coal, hydro‐plasticization of low‐rank coal was carried out. However, the caking property of low‐rank coal cannot be obviously improved under mild conditions in the traditional tetralin‐H 2 system. This study is to investigate the feasibility of mixed tetralin‐glycerol as a solvent in the process of low‐rank coal hydro‐plasticization. The...
