A simple distillation method using conduction type thermogravimetric meter (TG) on coal-derived liquids was investigated.
It was found that under the following measuring conditions, this distillation method was good agreement with the standard distillation method (ASTM D-2892) which is used crude oil.
1) Thermoelectromotive force difference in thermocouples between the heat buffer cover and sample container (bias voltage): 300μV
2) Quantity of samples: 300-400mg It was also possible to measure the water content in coal-derived liquids with this method. The one-cycle measuring time required for the TG distillation method using a conduction type thermobalance was less than 90 minutes and this method was far quicker and easier than other methods. Furthermore, in terms of accuracy, it was considered that the method can com-pare well with the ASTM method.
