Abstract: The method serves for cleaning dust-laden synthesis gases (1) which are formed in reactors or shaft furnaces (2) by carbothermal and/or electrothermal processes and which after departing the reactor or the shaft furnace at elevated temperatures are freed from dusty solids (4) via physical separation techniques (3) and are cooled by means of a downstream heat exchanger (5). In order to achieve a combination of long filter service life with effective synthesis gas cleaning, the proposal is that the dust-laden synthesis gas (1) after departing the reactor (2) and before being freed from dusty solids be passed in the presence of steam via a residence section (6), with the difference between the final gas temperature (T3) of the synthesis gas after it has been freed from the dusty solids and cooled and the maximum gas temperature in the residence section (T2) being set to at least 400 K.
