ABSTRACT:

The work on Task 3. Testing of Previously Synthesized Catalysts was initiated in early October as scheduled. Two initial tests were not successful (runs SB-2764 and SB-3064). It took us a great deal of time and effort to overcome these problems, which included conducting a blank test (run SB-3184) and a test of commercial Ruhrchemie catalyst (run SB-3254).  Finally, a successful test of catalyst with nominal composition 100 Fe/5 Cu/6 K/24 SiO(sub 2) (run SB-3354) was completed using a different slurry medium (Ethylflo 164 oil). Low activities in unsuccessful tests SB-2764 and SB-3064 may be due to catalyst poisoning by impurities in the initial slurry medium (purified n-octacosane from Humphrey Chemical Co.).
