    Table 3 shows the BET surface area of both the fresh and hydrothermally aged SCR catalysts. For fresh BEA zeolite and SCR catalysts, as the doping amount of catalytic additive increases, the BET surface area decreases, probably because the additive Cu, Ce, and Nb species blocked some of the zeolite channel, hindering the entry of N2 into the pores (Bin et al. 2014). After aging at 600 °C, all the samples showed 3-20 m2/g increased BET surface area. Aging condition of 600 °C is a relatively mild…

    slavery has been of mammoth economic importance. The South used the slaves in growing cotton. The cotton picked by the slaves made up over 80% of the exports from America (U.S. Department of the Interior, National Park Service. Slavery: Cause and Catalyst of the Civil War, 1). The cotton export was the most important business in America, for both the south and the north. Slavery was one of the most cost effective means of production to earn money in a labor intensive environment, and without…

    Anderson, Laurie, H. (2002). Catalyst. New York, NY: Viking. Kate Malone, a high school senior who is an A student, a math and science geek, a star athlete and who has a boyfriend, organizes her life in details as logically as the periodic table is organized. But things do not go as well as she thinks and everything in her life happens just like a catalyst in a chemical reaction. Kate is not accepted at MTI, the only university where she applied. Kate’s neighbors move in with her and her…

    the girl that gets harassed and ostracized for being an “appalling nerd” and because of this, vital aspects of my personality began to change and I morphed into an entirely different person. Through this journey, I learned that my self-hate was a catalyst for self-love and appreciation. Having always been considered an unusual girl in the eyes of my peers, I'd never been truly comfortable in my skin. Eventually, this uncomfortableness blossomed into self-hate that manifested itself in…

    Sydney 2000 Sports are always an interesting topic. Mega sport events are major catalysts to cultural globalization. The Olympics are a pretext for social pleasure, a background, a cultural wallpaper element of a social environment. It is a major catalyst to the longitudinal and fluctuating transformation processes which undermine the local culture at all levels to concurrently construct a common global culture. Compared to other topics in globalization, sporting events rely on deference’s and…

    CuMnRC1, CuMnRC2 and CuMnRC3 catalyst was 0.675µm, 3.127µm and 7.435µm respectively. The particles of CuMnRC1 catalyst was least agglomerated, highly porous, high surface area and uniformly distributed. The choice of different precipitant in the CuMnOx catalysts leads to the change of the surface distribution of Cu, Mn and O elements, which might be related to the CO oxidation catalytic performance of the catalysts. Table 2: Particle size of CuMnRC catalysts Catalyst Particle size (µm) CuMnRC1 0…

    3.2 Effects of particle size The particle size of the catalyst was highly influenced on the reaction rate, when the particle size of the catalyst was decreased, therefore their surface areas was increased and the ratio of catalyst surface and reactant volume was playing a crucial role for controlling the reaction kinetics. The reaction was takes place on the surface of a substance, increasing the surface area should increases the quantity of the substance that is available to react, and will…

    CHAPTER 4 RESULTS AND DISCUSSION 4.1 Incomplete Carbon Glucose Preparation for sulfonated solid acid catalyst must undergo a process which is called carbonization or pyrolysis. Glucose is natural organic compounds had been used as starting raw material because it is cheap and less toxic. Carbonization is an important step before the sulfonation process because it will form amorphous carbon composed of small carbon sheets [B] and produced sites for sulfonic group to be attached or…

    The carbon supported PtFeS catalysts were prepared by a modified polyol method. In brief, 0.3 g carbon (Ketjen-black heat-treated at 2250 °C, SE = 160 m2 g-1) was dispersed in 135 g ethylene glycol. 5.993 g of 8 wt% H2PtCl6 (Umicore; Pt content, 39.8 wt%), 1.874 g of 8 wt% FeCl3. 6H2O (Sigma-Aldrich), and 0.352 g of 8 wt% (NH2)2SC (Sigma-Aldrich) previously mixed in ethylene glycol were added to the dispersion. The pH of the stirred reaction mixture was adjusted to ∼11 using 1 M NaOH dissolved…

    NMR as well as IR should be performed to determine the purity of the final product (melting/boiling point can also be used) and if possible any possible side products that may have been produced should also be identified. Introduction: A catalyst is a compound that increases the rate at which a reaction occurs and…
