ON THE SEPARATION OF ORGANIC MACERAL DURING THERMAL SIMULATION OF HYDROCARBONS FROM COAL

In view of the demand from thermal simulations from coal,the paper detailed the method and process of the centrifugal separation of organic mono-maceral by using ZY-1 inorganic heavy liquid.Three steps are involved with the process of separation and enrichment:selection of grain size for sample crushing,conditional test and preparative enrichment.Several samples are separated and enriched,and the highly pure maceral derived from the process above can meet the demands for thermal simulation.Additionally the density areas of different organic macerals are located.
