Mass and Elements Balance of Polish and Czech Hard Coal Pyrolysis Process

详细

Laboratory coking test is very often used for prediction of produced coke quality. The second route for results utilisation is differentiation of products and determination of its yield. There were not carried out many tests to check if mass balance sums to one. In addition to this there were not performed test to control elements balance if there were made further ultimate analysis of products.

In order to control mass and elements balance there were carried out laboratory coking tests of several coals with ultimate analysis of coals, coke and by-products. There were found good correlations between some products and volatile matter in origin coal. It confirms that for them there is rational for its prediction from quality parameters of coal.
