A process for the utilization of tar which is separated from the gases derived from gasification of granular fuel under pressure, especially of bituminous coal, and in which the tar separated from the gases in fed back into the pressure gasification cycle of the fuel. The tar is added as a binder in the pelletisation of the fine grained portions of the fuel and is fed into the generator as a constituent of the pellets. Apparatus for carrying out the process comprises a pressure generator having a feed device for granular fuel, a tar separator, and a pelletising device connected by a tar conveying pipe to the tar separator, for the addition of binder to the granular fuel, the pelletising device conveying the pellets produced thereby into the feed device. The granular fuel is screened to pass only that portion below a predetermined grain size to the pelletiser, the remaining portion being fed directly to the generator. |
