Summary:

Nineteen catalysts were prepared by either (a) evaporation of metal nitrate-citric acid solutions; (b) coprecipitation of nitrates with carbonates; (c) mechanical blending of the metal oxide (or nitrate) powders or (d) modification of commercial methanol synthesis catalysts. Fourteen catalysts were tested in either the Berty gradientless reactor or the plug-flow reactor. Previously reported selectivities to liquid products were determined with a more refined gas chromatographic system, show that C/sub 4/-C/sub 9/ HC were also present in the liquid product in addition to the alcohols. A sample of liquid product recovered from a 100 hour test made with a CuZn/sub 0/ /sub 125/CrCoK/sub 0/ /sub 11/ catalyst was analyzed by GC and found to contain 55.9 wt % C/sub 1/-C/sub 6/ linear alcohols, 33.0% C/sub 1/-C/sub 7/ aldehydes, 9.2% C/sub 5/-C/sub 9/ paraffins and 1.9% unidentified oxygenates. A preliminary techno-economic assessment of three potential synthesis reactor systems - liquid-fluidized, multi-tube, jacketed fixed-bed or adiabatic fixed-bed - was made which indicated that there are significant capital cost and operating cost savings associated with the use of a liquid-fluidized reactor system.
