        Wet synthesis experimental test was performed in 2 reactors:  The 1^st containing 55 l. of catalyst-oil mixture, the 2d, 85 l.  Ten l. of catalyst (100 Fe:5 Cu:10 Mn:100 kieselguhr) per reactor were found to give the highest conversion yield (73-75% in a single stage and 93-94% in 2 stages).  The theoretical yield of 170 gm. has been reached in a 2-stage test with a total conversion of CO+H₂=90-93%.  The average operating temperature varied 230°-250°.  The synthesis pressure was 15 atm.  The formation of CH₄ was lower throughout than in the corresponding dry synthesis test.  When catalysts are used that produce paraffin preferentially and have a low tendency for producing CH₄, and average gasification of 3-4% may be counted on with a total conversion of 70-90%.  The consumption ratio CO:H₂ was shifted towards the H₂ side in comparison with the dry synthesis.  In the 1^st stage, the ratio was mostly greater than 1:1.30.  IN the 2d stage, however, the reverse is true, and the consumption ratio is equal to about CO:H₂=1.0:0.90.  The total consumption ratio in the 1^st and 2d stages corresponds tot he proportion in the water gas and varies between 1:1.24 and 1:1.26.  As in the dry synthesis, the composition of the products depends primarily on the nature of the catalysts and secondarily on experimental conditions such as temperature, pressure, circulation, etc.  The products are always somewhat more saturated than in the dry synthesis.  The tests have been run for 7.5 weeks without much reduction in activity.  The gas throughput consisted of 1 synthesis gas to 2.5-3.0 recycle gas.
