The WVU plug-flow microreactor system is now complete. Screening runs with this system will commence. Computer control is being installed in the second WVU unit. Additional hardware has been suggested for this system so that it can be used either to screen additional catalysts or to obtain kinetic data on selected catalyst samples. Synthetic preparations and characterizations of molybdenum-based sulfide and nitride catalysts are ongoing. Modelling studies are continuing satisfactorily. A more detailed model of the reaction kinetics, to account for individual alcohols rather than a lumped highter-alcohol, has been inserted into the model of a plug-flow reactor. A solution methodology to maximize the profitability of alcohol production, separation and blending has been developed. The temperatures, pressures, flowrates, and key component recoveries in the separation steps are the optimization variables. The probability of this process becoming economically feasible in the near future appears to be extremely small given the low return on capital investment associated with the production of alcohol from coal. If coal derived alcohols are to become alternative transportation fuels, then the capital cost associated with the process must be reduced, specifically the cost of the gasifiers, or significant changes need to be made in the composition of the mixed alcohol product. A methodology for performing Monte Carlo studies to determine quantitatively the uncertainties relevant to future decisions to build an alcohol-fuels plant is still being developed.
