摘要： PURPOSE:Tar vapor and water vapor are allowed to condense on the surface of dry-distilled low-quality coat batchwise to increase its calorie and simultaneously improve water-proofing properties whereby the moisture absorption and spontaneous ignition are prevented during transportation and storage. CONSTITUTION:Low-quality coal is preliminarily dried with low-temperature heat transfer medium, then high-temperature heat transfer medium is employed to effect drying and dry distillation. The resultant dry-distilled coal is cooled down with a coolant in the same heat exchanger, while the tar vapor and water vapor generated by dry distillation is sent to the other heat exchanger where they are allowed to condense batchwise to coat the surface of the dry-distilled coal. Thus, the low-quality coal is modified. Each process is carried out using 4 or more heat exchangers A, B, C, D by switching with time.

摘要： PURPOSE: To remove aldehyde in a polyester, effectively, and to obtain a polyester having high qualities and high polymerization degree, by dividing the temperature zone of a reactor for the solid phase polymerization of polyester into the zone for the removal of acetaldehyde and the zone for increasing the polymerization degree.
CONSTITUTION: Polyethylene terephthalate polymer pellets having a number- average polymerization degree of, e.g. 80W120, are fed continuously to the solid phase polymerizer 4. At the first temperature zone, the removal of acetaldehyde existing in the polymer as an impurity is accelerated by introducing inert gas through the inlet pipe 6 to the polymerizer keeping the temperature of the polymerizer pref. at 210W220°C, thereby suppressing the increase of the polymerization degree. At the second temperature zone F
1 placed below the first temprature zone, the polymer pellets are maintained pref. at 230W240°C to promote mainly the increase of the polymerization degree, and the polycondensation product having a polymerization degree of e.g. 140W200 is taken out of the polymerizer continuously through the extraction valve 5.
