The production of a hydrogen-rich synthesis gas from coal char and steam was investigated in a 12-in. diameter, continuous electrofluid reactor. The reactor has been operated at temperatures approaching 2000°F and using both single and three-phase ac power. Data on the gasification rate and the electrical characteristics of the system were taken and several different electrode materials were tested. A large part of the interelectrode resistance seemed to be due to contact resistance. Electrode life remains a problem.
