Book Description
This research title is Fischer-Troprch(FT) Synthesis Of Hydrocarbon Over Mesoporous Co/SBA- 15 Catalyst : Influence Of Cobalt And Zinc Precursors Loading. The FT process is a set of chemical reaction that convert mixture of carbon monoxide and hydrogen into liquid hydrocarbons. The objectives are about to synthesis S B A- 15 mesoporous silica, to synthesis Co - Z n/ SB A- 15 mesoporous catalyst and to determine the influence and effect of promoter on the catalytic properties.The synthesis of Co- Z n/SB A- 15 catalystis prepared by an impregnation method. Cobalt nitrate and Zinc nitrate will be used as precursors and promoter respectively and being introduced as metal to the catalyst. Fourier Transform Infrared (FTIR) isused to identify types of chemical bonds in the catalyst where then Si-O- Si functional group is detected because of the present of silica from Tetraethyl-orthosilicate, TEOS. Themorphology of the catalyst surface determined by Scanning Electron Microscope( SEM) and it is analyzed that the catalyst to have'rope-like' structure and no change in morphology after modification. After Cobalt and Zinc is added, X-ray Diffraction (XRD) has detected that there are cobalt crystalline formed and the amorphous shape graph of Pure SBA15 is changed with new peeks detected due to intensity changes.The best BET surface area analyzed is 375.9021m2 /g by the sample of 10% Co 15% Zn-SBA15 catalyst which also poses big pore volume of 0.480953 cm3 /g. Thermogravimetric Analyzer (TGA) measured the decomposition of the samplesat temperature of 100°C, 250C, 300C and 450C which caused by decomposition of adsorbed water, organic functional group, dehydroxylation of silicate and nitrate group respectively.Thus, with all revenues collected from all the tests and compared with previous studies, this study found to be one small achievement in the catalyst industry.

Book Description
This book is based on a symposium held during the 248th American Chemical Society meeting that focused on use of the Fischer-Tropsch process in producing synthetic fuels. Its contents reflect the four dominant subjects of the meeting: catalyst preparation and activation, catalyst activity and reaction mechanisms, catalyst characterization and related reactions, and topics concerning commercializing the Fischer-Tropsch process. It covers recent developments related to renewable resources and green energy and provides a glimpse of the commercial potential of the Fischer-Tropsch process in synthetic fuel production.

Book Description
Fischer-Tropsch synthesis (FTS) is one of the most promising ways for the conversion of syngas to hydrocarbon products. Supported cobalt is the preferred catalyst for FTS due to its high selectivity to heavy hydrocarbons, low activity for water-gas-shift reaction and comparatively low price. Cobalt loaded SBA-15 catalysts were prepared by two different techniques including wetness impregnation and direct-synthesis methods. The characterization of the synthesized samples was done by X-ray diffraction (XRD), scanning electron microscopy (SEM) and N2 adsorption-desorption,. XRD measurements showed that the calcined cobalt catalyst did not modify the structure of SBA-15, proving that Co was present under the form of Co3O4 in the catalyst. The hexagonal structure of pores of SBA-15 was confirmed by SEM images for all samples.BET surface area showed that Co/SBA-15 catalyst prepared by direct synthesis method was produced high surface area and pore volume compared prepared by wetness impregnation method.

Book Description
Fischer-Tropsch synthesis (FTS) is a part of gas-to-liquids (GTL) technology, which produces synthetic liquid hydrocarbons from natural gas. Recently the production of clean fuels and particularly of synthetic diesel by means of the FTS process has aroused renewed interest in both industrial and academic field. This process was shown to be catalyzed by certain transition metals, such as Co which present the highest activity. This research work is about the synthesis of SBA-15 and preparation of catalyst with different promoter Zr, Zn, Mn - Co based supported by SBA-15 by wet impregnation catalysts and characterizes all sampling. All materials were characterized by several physico-chemical techniques such as TGA, SEM and FTIR. The catalytic and characterization results show a great influence of mesoporous support porosity on the structure, reducibility and FTS catalytic behavior of cobalt oxide species supported over these ordered materials. After modification of SBA-15 by Co with different loading, the particles found to be attached closely with each other. The SEM picture shows a large number of SBA-15 particles attaching closely with one another. So this will make catalyst more efficient and effective during FT process. Then, using FTIR, the functional groups will be observed with certain wavelength in the samples such as cobalt oxides, Si-O-Si, Si-CH3, zinc oxide, OH band, Si-C, and others. Besides that, the identification of metal inside SBA-15 was determined by comparing the pure SBA-15 with the incorporated metal on SBA-15. For this research, the characterization of the catalyst by selecting Zn as promoter have quiet similar characterization with noble metal that already investigate.

Book Description
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.
