✦ Synopsis

A combined demineralization-agglomeration two-stage process for salty coal is introduced for increasing quality and yield of coal concentrates.

The salt was dissoluted and removed by coal treatment with 0.1-0.3 mass% oil. After demineralization 3-20 mass% of oil was added to the coal hydromixture The resulting coal concentrate has ash content of 6-lo%, moisture content of lo-12%, and salt content ~0.4% per dry mass.

## Abstract The solvent molecules included in the clathrates (δ‐form) of syndiotactic polystyrene (s‐PS) are removed by suitable extraction procedures. An emptied δ‐form is produced which is different from the known γ‐form obtained by heating. The structural changes induced by thermal treatments on
