Abstract:
The effect of precursors of Co/γ-Al2O3 catalysts prepared from Co(NO3)2 and (CO)6Co2CC(COOH)2 on the Fischer-Tropsch synthesis (FTS) catalytic performance were investigated. All catalysts were characterised by TGA, BET, pore size distribution analysis and TEM techniques. For Aluminium-supported catalyst, the use of cobalt carbonyl cluster as cobalt precursor resulted in a higher activity and C5+ selectivities compared with the reference catalyst prepared from nitrate at low reaction temperature. The activities can be correlated with the zero valent cobalt metal exist on the support. The chain growth attribute to well dispersed smaller metallic cobalt particles resulted from the partial removal of terminal carbonyls at 150°C.

Abstract:
AbstractReactions of the Collman reagent, Na2[Fe(CO)4]·1.5 dioxane, towards the nitrosyl carbonyls [CoNO(CO)3] and [Fe(NO)2(CO)2] in THF as the solvent at room temperature were investigated. Thereby a quick transfer of one nitrosyl ligand from the nitrosyl carbonyl molecule to the iron carbonyl metalate was observed. The reaction with the cobalt compound afforded in high yields the well-known species [Co(CO)4]− and [FeNO(CO)3]− isolated by addition of two equivalents of [PPN]+Cl− ([PPN]+= bis(triphenylphosphane)iminium cation) and characterized by their known IR spectra, by elemental analysis and their characteristic colors and melting points. In the reaction of the Collman reagent with [Fe(NO)2(CO)2] a clean transformation to the tricarbonylnitrosylferrate(1−) as the only formed product was observed.

Abstract:
The cutting fluid is widely used in cutting process with the cemented carbide tool. This paper studied the influence of some antirusting aggents, such as triethanolamine, tri-sodium phosphate, benzotriazole, sodium carbonate anhydrous, on the cobalt leaching of the cemented carbide tool by soaking test. The test results showed that a cobalt on cememted carbide surface and triethanolamine can produce complex compound into solution that made the cobalt leaching. The cobalt of the cemented carbide with the ion of the tri-Sodium phosphate in a water solution can form the loose deposition which leaded to the cobalt leaching.The benzotriazole and the cobalt can generate complex compound film covering on cemented carbide to effective inhibits the cobalt leaching. The inhibitive effect about the cobalt leaching of the sodium carbonate anhydrous is carried out through cathode reaction. The cobalt leaching of cemented carbide tool is effective inhibited by adding the benzotriazole and the carbonate anhydrous in the water-based cutting fluid.

Cette these porte essentiellement sur l'etude de la reactivite des complexes polynucleaires du cobalt carbonyle. Le premier chapitre rassemble les informations bibliographiques concernant l'action des reactifs nucleophiles sur ces complexes. Le deuxieme chapitre est consacre a l'etude de la reaction de remplacement de carbonyles par d'autres ligands l dans le cluster etococco#3(co)#9, sous catalyse par transfert d'electron et sous activation thermique. Dans certaines conditions de solvant la reaction conduite sous activation thermique apparait anormalement rapide et cette observation revele l'intervention d'un processus auto-catalyse par transfert d'electron. L'etude de la reaction de decomposition des clusters rcco#3(co)#9 induite par les nucleophiles fait l'objet d'un troisieme chapitre. Les especes cluster anion sont engendrees lors de la reaction de decomposition. Elles sont a l'origine d'un processus d'auto-catalyse par transfert d'electron et ont ete identifiees par spectroscopie rpe.

Abstract:
This paper describes a theoretical device called a Petroleum Synthesizer, which absorbs the greenhouse gas carbon dioxide from the atmosphere and converts it into a synthetic petroleum fuel. The device has four parts: First, a CO2 Scrubber using sodium carbonate reversibly absorbs CO2 from the atmosphere. Simultaneously, a Hydrogen Generator separates water electrolytically to produce hydrogen (H2). Third, a Carbon Monoxide Generator mixes the H2 and the CO2 over a nickel catalyst, changing the constituents into carbon monoxide (CO) and water. Finally, the CO and additional H2 are combined in a cobalt-catalyst Fischer-Tropsch (F-T) Processor to produce gaseous and liquid petroleum products. Calculations show that one watt of electricity supplied for one year would allow the Synthesizer to create 0.420 kg of petroleum products, and absorb 1.314 kg of CO2 from the atmosphere. An acre of solar voltaic panels powering Synthesizers could produce 46,000 kg, or about 14,000 gallons, of petroleum products per acre per year, and absorb 140,000 kg of CO2. By contrast, an acre of corn produces less than 400 gallons of ethanol per year.
