An initial study on feasible treatment of Serbian lignite through utilization of low-rank coal upgrading technologies

- The current status in low-rank coal upgrading technologies is shortly observed.
- The specific attention to the utilization of drying technologies is given.
- The packed bed drying model is upgraded for the fluid bed drying calculations.
- Product-specific data (kinetic and equilibrium) of lignite are derived.
- The fluid bed drying model and relevant numerical procedure are given in details.
