Description

  • Content Description: Professors and graduate students from five universities--the University of Kentucky, University of Pittsburgh, University of Utah, West Virginia University, and Auburn University--are collaborating in a research program to develop C1 chemistry processes to produce ultra-clean liquid transportation fuels and hydrogen, the zero-emissions transportation fuel of the future. The feedstocks contain one carbon atom per molecular unit. They include synthesis gas (syngas), a mixture of carbon monoxide and hydrogen produced by coal gasification or reforming of natural gas, methane, methanol, carbon dioxide, and carbon monoxide. An important objective is to develop C1 technology for the production of liquid transportation fuel and hydrogen from domestically plentiful resources such as coal, coalbed methane, and hydrocarbon gases and liquids produced from coal. An Advisory Board with representatives from Chevron-Texaco, Eastman Chemical, Conoco-Phillips, the Air Force Research Laboratory, the U.S. Army National Automotive Center, and Tier Associates provides guidance on the practicality of the research. The current report summarizes the results obtained in this program during the period October 1, 2002 through March 31, 2006. The results are presented in detailed reports on 16 research projects headed by professors at each of the five CFFS Universities and an Executive Summary. Some of the highlights from these results are: (1) Small ({approx}1%) additions of acetylene or other alkynes to the Fischer-Tropsch (F-T) reaction increases its yield, causes chain initiation, and promotes oxygenate formation. (2) The addition of Mo to Fe-Cu-K/AC F-T catalysts improves catalyst lifetime and activity. (3) The use of gas phase deposition to place highly dispersed metal catalysts on silica or ceria aerogels offers promise for both the F-T and the water-gas shift WGS reactions. (4) Improved activity and selectivity are exhibited by Co F-T catalysts in supercritical hexane. (5) Binary Fe-M (M=Ni, Mo, Pd) catalysts exhibit excellent activity for dehydrogenation of gaseous alkanes, yielding pure hydrogen and carbon nanotubes in one reaction. A fluidized-bed/fixed-bed methane reactor was developed for continuous hydrogen and nanotube production. (6) A process for co-production of hydrogen and methyl formate from methanol has been developed. (7) Pt nanoparticles on stacked-cone carbon nanotubes easily strip hydrogen from liquids such as cyclohexane, methylcyclohexane, tetralin and decalin, leaving rechargeable aromatic phases. (8) Hydrogen volume percentages produced during reforming of methanol in supercritical water in the output stream are {approx}98%, while CO and CO2 percentages are <2 %.
