Fischer-Tropsch-Synthese an Monolith-Katalysatoren bei Rezirkulation der Flüssigkeit

Einsatz genetischer Algorithmen als Optimierungsmethode bei der Synthese elektronischer Schaltungen

Fischer-Tropsch chemistry at room temperature?

The unique catalytic activity of vanadium nitrogenase suggests a new direction for the direct production of biofuels from CO with either synthetic catalysts or nitrogenase-containing bacteria. The reduction of CO by V nitrogenase to light hydrocarbons shows striking similarities to the established Fischer-Tropsch process; however, the enzyme does not use H(2) directly for this reaction. ADP=ade...

Fischer-Tropsch Synthesis The CAER Perspective

The discovery of the catalytic synthesis of ammonia must rank as one of the important discoveries by mankind. In addition to providing the fertilizer needed to feed an expanding population, Fritz Haber’s recognition of recycle processing combined with the developing German technology to handle high pressures of hydrogen, led a major revolution in the chemical industry. In rapid succession, the ...

The optimally performing Fischer-Tropsch catalyst.

Microkinetics simulations are presented based on DFT-determined elementary reaction steps of the Fischer-Tropsch (FT) reaction. The formation of long-chain hydrocarbons occurs on stepped Ru surfaces with CH as the inserting monomer, whereas planar Ru only produces methane because of slow CO activation. By varying the metal-carbon and metal-oxygen interaction energy, three reactivity regimes are...

Synthese und Untersuchung der Lanthanoidoxidnitrate

The lanthanide oxide nitrates LnONO3 with Ln = Pr, Nd, and Sm-Yb were synthesised by thermal decomposition of hydrated lanthanide nitrates. The compounds were refined isotypically to YONO3 in the tetragonal space group P4/nmm and the structure is closely related to the PbFCl-type. Because of the orientational disorder of NO3− in this structure refinement a possible superstructure is discussed. ...
