Work has been completed on Phase I (Feasibility Study); Phase II (Bench-scale Research); and Phase III (Pilot Plant Engineering). Work on Phase IV (Pilot Plant Construction and Operation) is continuing. During Run 46C the inlet steam partial pressure to the gasifier was increased from the normal 11.6 atm to 12.5 atm. This seemingly small change produced the hoped-for responses. Both the acceptor activity and particle density increased, thereby showing that some liquid had formed in the system: CaO-Ca(OH)/sub 2/-CaCO/sub 3/. Boot operation was stable, showing that the extent of liquid formation was not enough to cause agglomeration of the acceptor. After the balance period, the steam partial pressure was increased but a control valve malfunction caused a shutdown. The new 2-in. single tube methanation reactor was operated for the first time. Results will give valuable design data on the effect of diameter for packed tube reactors.
