An analysis of the fitted parameters for a commercial Cu/ZnO/Al2O3 catalyst suggests that a more open Cu surface, for example, Cu(110), Cu(100), and Cu(211) partially covered by oxygen, may provide a better model for the active site of methanol synthesis, but our studies cannot exclude a synergistic effect with the ZnO support.

Mechanism of Methanol Synthesis on Cu ..

As Staff Member she Participated in projects on the controlled oxidation of methane to methanol, catalysis in coal gasification, Fischer-Tropsch synthesis, and water gas shift reaction, a molten salt process for production of hydrocarbon fuels from oil shale. She did the first macroscopic-liquid phase laser isotope separation. Developed photochemical applications for reprocessing of nuclear fuel. Designed and constructed the highest energy dye laser. Measured first quantitative UV-visible spectrum, Argonne National Laboratory. As a Student Aide she Studied mechanism of adsorption of plant pigments in solution-adsorption chromatography. Rofer organized a NATO Advanced Research Workshop: "Turning a Problem into a Resource: remediation and Waste Management at the Sillamae Site, Estonia." Co-Director with Toenis Kaasik. Technology Information Exchange Workshop, United States Department of Energy, Santa Fe, New Mexico. Workshop on Supercritical Fluid Processing of High-Risk Wastes, Sponsored by the United States Air Force and Department of Energy, Los Alamos, New Mexico.

Research on the development of catalytic transformations of simple oxygenates is still justified. New market conditions make the production and processing of oxygenates as part of the Fischer-Tropsch synthesis purposeful. On the other hand, the increase in the potential demand for ethyl acetate against the background of high availability of ethanol justifies further research on a direct one-step catalytic synthesis of this ester.

chain growth mechanism in oxygenate synthesis.

Obtaining synthesis gas, also known as the reforming process can be carried out in one stage, at which all energy-consuming reaction of the reforming flow in a single pipe installation reforming with water vapor. Application installation single-stage reforming process leads to the production of additional hydrogen. In another preferred embodiment, the synthesis gas may occur in the two-stage method of reforming, in the exercise of which the primary reforming process in the pipe installation reforming with water vapor is combined with the second stage reformer combustion in oxygen, which receive the synthesis gas with a shortage of hydrogen. Using this combination, there is a possibility to adjust the composition of the synthesis gas with the achievement of the most appropriate composition for methanol synthesis. Alternatively, autothermal reforming, in which offline installation reformer combustion in oxygen produces synthesis gas, characterized by the lack of hydrogen, followed in the process line by removing deoxidised to recover the target relation of hydrogen to carbon monoxide leads to a simplified process scheme with reduced capital costs. An important part of any stage of combustion in oxygen is the design of the burner. The burner mixes the hydrocarbon and oxygen and combustion in the flame creates heat for the conversion of hydrocarbons. The reaction conversion of synthesis gas to oxygenates, such as methanol, is limited by an exothermic equilibrium reaction, the occurrence of which contribute to low temperatures. Over a heterogeneous catalyst also requires high pressure, because of the reaction that produces methanol, show a reduction environment. As outlined in US no 3326956, the synthesis of methanol under low pressure based on the catalyst of copper oxide/zinc oxide/aluminum oxide, which among the various catalysts, including CIO/Zn/Al2About3, CuO/ZnO/Cr2O3, ZnO/Cr2O3, Fe, Co, Ni, Ru, Os, Pt and Pd, generally operates under a nominal pressure of from 5 to 10 MPa and at temperatures in the range of from about 150 to 450°C.
