Enhancing Cobalt Dispersion in Supported Fischer-Tropsch Catalysts Via Controlled Decomposition of Cobalt Precursors
Fischer-Tropsch synthesis is a part of Gas-to Liquids (GTL), Biomass-to-Liquids (BTL) and Coal to Liquids (CTL) technologies, which produce alternatives clean fuels from natural gas, biomass and coal. The catalytic performance of cobalt catalysts in Fischer-Tropsch synthesis strongly depends on the size of cobalt particles in nanoscale range (6-30 nm). Cobalt catalysts are usually prepared via ...
متن کاملIonic liquids as efficient catalysts for synthesis of phosphorylated dialkyl succinates containing phthalazin-1-one moieties
Ionic liquids such as 1,3-dialkylimidazolium salts make excellent catalysts and solvents for synthesis of dialkyl 2-(dialkoxyphosphoryl)-3-(1-oxo-1-H-phthalazin-2-yl)succinates from 2H-phthalazin-1-one, dialkyl acetylenedicarboxylates, and trialkyl phosphites. Under similar conditions, triphenyl phosphite led to dialkyl 2-(diphenoxyphosphoryl)-3-(1-oxo-1-H-phthalazin-2-yl)succinates. The ionic ...
متن کاملFischer Tropsch Synthesis: A Comparison of Iron and Cobalt Catalysts
Following WW II, it appeared that there would be a severe shortage of crude oil so that U.S. organizations initiated work on Fischer-Tropsch synthesis (FTS). Over a ten year period, the U.S. Bureau of Mines was budgeted $85 million for work on direct and indirect coal liquefaction. These funds would represent more than a billion dollars in today’s marketplace. A large (75 bbl/day) FTS pilot pla...

متن کاملCobalt selenium oxohalides: catalysts for water oxidation.
Two new oxohalides Co4Se3O9Cl2 and Co3Se4O10Cl2 have been synthesized by solid state reactions. They crystallize in the orthorhombic space group Pnma and the monoclinic space group C2/m respectively. The crystal structure of the two compounds are made up of similar building blocks; Co4Se3O9Cl2 is made up of [CoO4Cl2], [CoO5Cl] and [SeO3] polyhedra and Co3Se4O10Cl2 is made up of [CoO4Cl2] and [S...
