A process for at least partial gasification of solid organic feed material, in which a tar-containing low-temperature carbonization gas is obtained by low-temperature carbonization from the feed material in a low-temperature gasifier and the low-temperature carbonization gas is then converted to a synthesis gas in a high-temperature gasifier by partial oxidation and subsequent partial reduction. The low-temperature carbonization gas is admixed with a second gas. A plant equipped for carrying out the process includes a low-temperature gasifier for obtaining the low-temperature carbonization gas from the feed material, a high-temperature gasifier for obtaining synthesis gas from the low-temperature carbonization gas, and means for admixing the low-temperature carbonization gas with the second gas.
