JJi,c;uSSI #If. The i?ost notable overall feature of the results is the .qrogresuive increase in hydrazine yield obteined by tite use of a liqu-id absorbent and by pihing tne discharge. The himest averase. jield was obtained wit!i tile pulsing technique with or without liqcdd absorbent aid was approxinietely 15 gms if H /KMH. Isolated values as nigi? as 20 @as/ W h were obtaine8 %ut further experimental work is required before these values can be made reproducible. It is noteworthy that a yield of 15 pis/KMH is beginning to look comercially attractive although it must be remenbered that the fiiL;,.l. product cost will depend to a great extent on the cost of the product purification process downstream of the . reactor. There are several interesting features shown by this work which bear discussion. From the results set out in Fig. 2 to 4 it is evident that the hydrazine yield decreases with increasing discharge power intensity despite a corresponding increase in the decomposition of ammonia. The only reasonable explanation for this which 118s been advanced is that hydrazine is formed in the discharge bj a complex reaction mechanism and is subsequently decomposed by electron bombardment or other collision phenomena (4,6 ) . The use of a liquid absorbent resdts in a decrease in the slope of the energy yield-power density plot. This is well illustrated in both Pig. 2 and Fig.4 by comparing the slope of the plots with and drithout the use of liquid absorbent. This indicates that hydrazine is being reinoved from the diecharge by the liquid absorbent instead of being degraded. If the hydrazine were completely removed so that degradation did not occur the elope of this plot would be wither independent of discharge power or possibly positive. The very
