Nano Metal Oxide Frameworks (NOF): Development of New Heterogeneous Catalyst for the Synthesis of Furan Derivatives from GlucoseAbstract A surface modification approach has prepared a nanostructured organic framework connecting two metal oxide NPs. The surface modifier attached two metal oxide NPs via molecular interaction to generate modular structures of fiber, rod, or sponge materials. Thus, obtained hybrid sy [...] 840 4801 |

Abstract This paper investigates how the aggregation of bimetallic nanoparticles (NPs) influences the electronic condition of the surface adsorption site and, hence, the performance of materials during the electrooxidation of fuels in an alkaline medium. First, we synthesized Pt-Ni NPs in three configuration [...] 752 4736 |

Abstract Due to its similar characteristics to titanium, niobium has become an attractive alternative in photocatalytic processes. Research indicates that titania has an optimal percentage of phases resulting in a commercial catalyst, P25, that contains more than 70% anatase with a minor amount of rutile and [...] 735 5144 |
Enhancing Kerosene Selectivity of Fischer-Tropsch Synthesis by Periodical Pore Drainage Via Hydrogenolysisby
Carsten Unglaub
and
Andreas Jess
Abstract Accumulation of wax inside the catalyst pores during transient cobalt-catalyzed Fischer-Tropsch synthesis (FTS) leads to unfavorable product distribution and low activity by imposing internal mass transfer limitations. The condensation of paraffin severely changes the apparent product stream that ac [...] 946 7410 |
Research and Application of Modified ZSM-5 for the Process of Alkylation of Oil Distillate FractionsAbstract In the oil distillate fraction alkylation process, a modified Zr zeolite ZSM-5 was obtained and studied. The modification was executed using a method that impregnated ZSM-5 with a 5% solution of ZrOCl2∙6H2O.

Abstract With increasing population levels and rapidly growing industries worldwide, the purification of water contaminated with different impurities is one of the biggest challenges we face in recent times. Photocatalysis holds great potential as an efficient mineralization process to remove the foreign mat [...] 884 7618 |
Production and Characterization of Carboxymethylcellulase by Submerged Fermentation of Moniliophthora perniciosaAbstract Microorganisms that are capable of degrading lignocellulolytic materials can produce extracellular cellulase complexes. Microorganisms are an excellent alternative for the production of cellulolytic complex, since these sources have a high power of multiplication. In this work, we researched the pro [...] 617 5146 |
