Abstract
This application describes a process and apparatus for gasifying sulphur bearing coal in a molten iron bath which is covered with a sulphur absorbing slag. In order to make the process practical, the hot liquid slag is transferred to a second vessel in which it is desulfurized by contact with an oxygen containing gas, and then returned as hot liquid slag to the iron bath for reuse.
