The tar of Shulan brown coal obtained from flash pyrolysis at a tempera- ture of 700℃ was investigated by using capillary gas chromatography, It was compared with that obtained by high temperature (1000℃) pyrolysis of bitumi- nous coal. Both were preliminarily treated by fractional distillation and so- lvent extraction with CS2. The part of distillate below 28℃ of the tar from Shulan brown coal and that of high temperature pyrolysis of bituminous coal amounted to 42.9% and 20.6% of the total tar respectively...

The tar of Shulan brown coal obtained from flash pyrolysis at a tempera- ture of 700℃ was investigated by using capillary gas chromatography, It was compared with that obtained by high temperature (1000℃) pyrolysis of bitumi- nous coal. Both were preliminarily treated by fractional distillation and so- lvent extraction with CS2. The part of distillate below 28℃ of the tar from Shulan brown coal and that of high temperature pyrolysis of bituminous coal amounted to 42.9% and 20.6% of the total tar respectively and distillates below 245℃ were 24.31 % and 16.83 % respectively and were analyzed chromatographically. The following peculiarities of the tar obtained from flash pyrolysis of Shulan brown coal were ascertained: (1 ) Larger amount of lower--boiling fraction; (2 )Higher content of lower phenols; and (3 ) Lower content of naphthalene. In the light of industrially important chemicals, the distribution of phen- ols and basic and neutral substances in the tars were discussed. CS2 extrdction~capillary gas chromatography a new method of analyzing coal tar with the advantages of using less sample and easy to operate was suggested. Its applicability in the analysis of coal tar was also discussed.

The article deals with the replacement of normal carbonization and ashing method for treating heavy oil sample with the dissolving sample method of using nitric acid as solvent in a braising pot with, increasing pressure and low temperature. The experiment shows that the sample contained in the braising pot which is placed in dry oven with constant temperature of 160 centigrade changes into yellow transparent liquid in 4 hours. The obtained liquid can be used to determine nickel and vanadium with polarographic method. This method can prevent the environment from pollution and use less sample. The cond'tions of the bottom liquid for determination of nickel by the polarographic method of dime thylglyoxitne have been optimized. It has been confirmed that there is a linear relation in the range of 0-0.05 ppm of nickel concentration. The measuring sensitivity has increased by 4 times or more. Under the condition of limited determination of nickel content by dissolving heavy oil sample in braising pot the relative error is less than 7% (based on spectral determination values of AAS and ICP), standard deviations less than 0.97, variance coefficients less than 3.1%.
