IN SITU SILICA SUPPORTED METALLOCENE CATALYSTS FOR ETHYLENE POLYMERIZATION
Bis(2-R-ind)ZrCl2 (R: H or phenyl) was supported on different types of silica by in situ impregnation method and used for ethylene polymerization. In this method, the step of catalyst loading on support was eliminated and common alkyl aluminum (triisobutylaluminum, TiBA) cocatalyst was used instead of expensive methyl aluminiumoxane (MAO) cocatalyst in the polymerization. The effect of surface ...
متن کاملThe production of carbon nanofibers and thin films on palladium catalysts from ethylene–oxygen mixtures
The characteristics of carbonaceous materials deposited in fuel rich ethylene–oxygen mixtures on three types of palladium: foil, sputtered film, and nanopowder, are reported. It was found that the form of palladium has a dramatic influence on the morphology of the deposited carbon. In particular, on sputtered film and powder, tight ‘weaves’ of sub-micron filaments formed quickly. In contrast, o...
متن کاملCatalysts Supported on Carbon Materials for the Selective Hydrogenation of Citral
The heterogeneously catalyzed selective-hydrogenation of citral is one of the more feasible ways for obtaining its appreciated unsaturated-alcohols, nerol and geraniol, which are present in over 250 essential oils. Thus, citral has very recently come to be produced petro-chemically in very large quantities, and so partial hydrogenation of citral has become a very economical route for the produc...
متن کاملEthylene combustion on unsupported and supported Pd: a comparative study
Ethylene combustion is studied at elevated pressures on Pd(100) and compared with supported Pd catalysts. Specific rates of CO2 formation were determined on Pd(100), 1 wt% (dPd = 2.5 nm) and 5 wt% (dPd = 4.2 nm) Pd/SiO2 catalysts as a function of the O2/C2H4 ratio over the temperature range 428–473 K. Reaction rates and apparent activation energies on these catalysts are particle size and react...
متن کاملComparative Studies on Effect of Pretreatment of Rice Husk for Enzymatic Digestibility and Bioethanol Production
Three common pretreatment processes based on dilute sulfuric acid, dilute sodium hydroxide and heat treatment (autoclaving) followed by enzymatic hydrolysis were evaluated to provide comparative performance data. Among them, the best result was obtained when the pretreatment of rice husk was carried out with 3% of NaOH solution. The pretreatment of rice husk with NaOH substantially increased th...
