Abstract

A process for removing the acidic compounds HF, HCl, SO2, SO3 and/or H2S from gases arising in the combustion or gasification of fossil fuels is described. In this process, the hot gases are contacted with a melt of oxides, hydroxides and/or carbonates of Li, Na, K, Mg and/or Ca at a temperature from 500 to 1000 DEG C.
