Slurry catalyst with 2-ea
Webb15 sep. 2007 · Catalysts for slurry-phase hydrocracking of heavy oil have undergone two development phases, that is, heterogeneous solid powder catalysts and homogeneous … WebbMeOH-based slurry than in the IPA-based slurry, and a much smaller aggregate mean diameter. The mean diameter of the PtRu/C catalyst–ionomer agglomerates was found to be 225.7 nm in the MeOH-based slurry and a further increase of 235.6 nm in the IPA-based slurry. As we have seen, the agglomerate size of the catalyst slurry varied depending on …

WebbThe CuZnAl slurry catalysts have been prepared by a complete liquid phase technology and characterized by X-ray diffraction, H 2 temperature-programmed reduction and temperature-programmed desorption of ammonia. The activity of the catalysts for direct synthesis of DME from syngas is evaluated in a slurry reactor. WebbIncreased yields and flexibility: The ISOCRACKING Two-Stage Recycle process is optimized for maximum yields of premium products with minimum hydrogen consumption. The first stage removes feed impurities and converts 20-50% of the feed. The second stage cracks the cleaned feed at lower temperatures. Revamp for better products and better …
WebbTwo important continuous slurry processes are used the Exxon (Vistanex) process with A1C13 catalyst and the BASF process (Oppanol), which polymerizes isobutylene dissolved in ethylene (in a ratio about 1 2) in the presence of BF3. Ethylene serves as the internal cooler. [Pg.774] Webb3 juli 2006 · Journal of Catalysis Oct 2007 ... EA, were obtained at lower potentials (e.g., 0.60 eV at 200 mV and 0.32 eV at 300 mV). The EA was <0.21 eV in the range 400−700 mV, ... wherein the undissolved solids content of a slurry during said processing stages reaches a weight percent of at least 15%.
