FIELD: chemistry.
SUBSTANCE: invention relates to composition and method of mercury removal from flows of discharge furnace gases. Composition for removing mercury from products of fuel combustion contains source of bromine, source of chlorine and sorbent, able to absorb bromine and chlorine, with value of IERP of composition exceeding IERP of sorbent by 10°C. Method of mercury removal from fuel combustion products includes supply of composition into flow of discharge gases, obtained in the process of combustion of one or several types of burnt fuel, combustion of burnt fuel, obtaining flow of discharge gases with reduction of mercury emissions from flow of discharge gases. In one of the versions of method realisation supply of composition into burnt fuel is realised before and/or in the process of combustion of burnt fuel.
EFFECT: invention provides composition with improved temperature stability and profitability method of minimisation of mercury emissions, which are formed in the process of combustion of coal and other types of fuel.
