The results of studying effects of coal and carbonaceous wastes chemical modification on yields and properties of the thermolysis liquid products were summarized . The most effective reagents were organic substances (including liquid waste of hydrocarbon nature), halides of transition metals (ZnCl2, FeCl3) and alkali metal hydroxides (NaOH, KOH). In terms of increasing the yield of liquid products, the modificator maximum activity reveals in the main thermal decomposition range (300-500 º C). Their effect depends on the introducing method, the modificator content, heat treatment regime, and nature of organic raw materials
