Book excerpt: La present tesis va consistir en el disseny de nous nanocatalitzadors de cobalt per a la reacció de Fischer-Tropsh (FT). Les nano partícules de Cobalt van ser sintetitzades utilitzant diferents metodologies: reducció química utilitzant borohidrur de sodi com agent reductor o, descomposició tèrmica de compostos organometàl·lics tals com Co2(CO)8. Les síntesis van ser realitzades en presència de polímers com agents estabilitzants. Després de la síntesis, les nano partícules de cobalt foren aïllades, caracteritzades (utilitzant TEM, HR-TEM, XRD, XPS, ICP, FTIR, TGA i RAMAN) i provades en la reacció de Fischer-Tropsch en fase aquosa. Amb la finalitat de comparar amb catalitzadors suportats clàssics, les nano partícules de cobalt van ser immobilitzades amb TiO2 i provades en FT utilitzant un reactor de llit fix. En aquest estudi es va observar que l'activitat i la selectivitat de les nanopartícules de cobalt en ambdós sistemes catalítics depenien altament de paràmetres tals com el mètode de síntesis, el polímer estabilitzant i la mida de partícula. Aquestes diferències van ser atribuïdes a variacions en l'estructura i composició de les nano partícules que alhora eren intrínseques de cada paràmetre d'estudi.

Book Synopsis The Synthesis of Nano-sized Cobalt Particle Stabilized by Alkanethiol and the Characterization on the Surface by : Sangsoo Kim
Download or read book The Synthesis of Nano-sized Cobalt Particle Stabilized by Alkanethiol and the Characterization on the Surface written by Sangsoo Kim and published by . This book was released on 2010 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanosized cobalt particles prepared through a reverse microemulsion, introduced by Zhang, X. and Chan, K. [1], were modified by capping alkanethiol. The synthesis of ligands capped cobalt particle and the density calculation of ligands on the surface were firstly reported from this paper. The alkanethiol capped on the surface of cobalt particles prevented from them to coagulate each other by collision. The obtained reddish solution where cobalt particles stabilized showed two distinct UV-absorption peaks. The bondage between cobalt and ligand created new energy levels where free electrons could excite when UV-light was shined. The bondage also confirmed by the Co-S peak on SERS (Surface Enhancement Raman Spectra). The number of ligands bounded on the cobalt was determined by the chemical shift on NMR (Nuclear Magnetic Resonance). The density of ligands on each particle was calculated by TGA (Thermal gravitational analysis), AFM (Atomic Force Microscopy) and NMR. Also, the bondage breakage was detected by the weight loss from TGA and increase heat flow from DSC. The present work focused on assessing the usage of cobalt particles as a homogenous catalyst in the Fischer Tropsch process. To obtain single phase under the reaction condition, the proper feed ratio of CO, H2, and C6H14 (Hexane) was estimated by Peng-Robinson equation with Kij value.

Book Synopsis Iron and Cobalt Catalysts by : Wilson D. Shafer
Download or read book Iron and Cobalt Catalysts written by Wilson D. Shafer and published by MDPI. This book was released on 2020-06-23 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the turn of the last century when the field of catalysis was born, iron and cobalt have been key players in numerous catalysis processes. These metals, due to their ability to activate CO and CH, haev a major economic impact worldwide. Several industrial processes and synthetic routes use these metals: biomass-to-liquids (BTL), coal-to-liquids (CTL), natural gas-to-liquids (GTL), water-gas-shift, alcohol synthesis, alcohol steam reforming, polymerization processes, cross-coupling reactions, and photocatalyst activated reactions. A vast number of materials are produced from these processes, including oil, lubricants, waxes, diesel and jet fuels, hydrogen (e.g., fuel cell applications), gasoline, rubbers, plastics, alcohols, pharmaceuticals, agrochemicals, feed-stock chemicals, and other alternative materials. However, given the true complexities of the variables involved in these processes, many key mechanistic issues are still not fully defined or understood. This Special Issue of Catalysis will be a collaborative effort to combine current catalysis research on these metals from experimental and theoretical perspectives on both heterogeneous and homogeneous catalysts. We welcome contributions from the catalysis community on catalyst characterization, kinetics, reaction mechanism, reactor development, theoretical modeling, and surface science.
Book Synopsis Nanostructure Science and Technology by : Richard W. Siegel
Download or read book Nanostructure Science and Technology written by Richard W. Siegel and published by Springer Science & Business Media. This book was released on 1999-09-30 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Timely information on scientific and engineering developments occurring in laboratories around the world provides critical input to maintaining the economic and technological strength of the United States. Moreover, sharing this information quickly with other countries can greatly enhance the productivity of scientists and engineers. These are some of the reasons why the National Science Foundation (NSF) has been involved in funding science and technology assessments comparing the United States and foreign countries since the early 1980s. A substantial number of these studies have been conducted by the World Technology Evaluation Center (WTEC) managed by Loyola College through a cooperative agreement with NSF. The National Science and Technology Council (NSTC), Committee on Technology's Interagency Working Group on NanoScience, Engineering and Technology (CT/IWGN) worked with WTEC to develop the scope of this Nanostucture Science and Technology report in an effort to develop a baseline of understanding for how to strategically make Federal nanoscale R&D investments in the coming years. The purpose of the NSTC/WTEC activity is to assess R&D efforts in other countries in specific areas of technology, to compare these efforts and their results to U. S. research in the same areas, and to identify opportunities for international collaboration in precompetitive research. Many U. S. organizations support substantial data gathering and analysis efforts focusing on nations such as Japan. But often the results of these studies are not widely available. At the same time, government and privately sponsored studies that are in the public domain tend to be "input" studies.
