A B S T R A C T PROCESS AND REACTOR FOR THE PREPARATION OF SYNTHESIS GAS Gasifier wherein coal dust is introduced from at least one passage in its sidewall and oxygen-containing blast is introduced essentially perpendicular to the coal flow, preferably from below, so as to form a horizontal flat disc. The contact between the hot slag falling down in the bottom of the reactor and the oxygen causes a carbon-free slag and some preheating of the blast. Since burners are not used in the present gasifier difficulties of flashback and flame impingement are obviated. Moreover, the coal gasification is more efficient, because carbon remained in the slag is completely combusted while falling down through the rising oxygen stream.
