	Abstract:The lattice Boltzmann method (LBM) is applied to simulate three dimensional flows through ceramic matrixes. The simplified structures are generated randomly by computer. As a test of the lattice Boltzmann code, the relation between pressure drop and superficial velocity in porous medium is obtained which agrees well with Darcy’s Law. Local velocities of different pores are also analyzed. The velocity distributions are approximate to parabolas. Calculation results show that the Darcy number increases along quadric curves with the increase of sphere diameter and porosity.

	Abstract:Six kinds of materials (MCM-41, HY, mechanically mixed HY/MCM-41, SiO2, TiO2 and Al2O3) supported nickel phosphide catalysts were prepared by co-impregnation method and characterized by N2 BET specific surface area measurements, temperature-programmed reduction (TPR) and X-ray diffraction (XRD). Dibenzothiophene hydrodesulfurization (HDS) activities of these catalysts were measured at 553-613K and 4MPa in a three-phase fixed-bed reactor. Among these supports, siliceous MCM-41-supported nickel phosphide catalyst showed the best HDS activities because of its high surface area and week interaction with active compositions. Nickel phosphide supported on all aluminum containing supports showed lower activities, especially for Al2O3, as the aluminum in the support interacts strongly with phosphorous. An in-depth study on mechanically mixed HY/MCM-41-supported nickel phosphide showed that the properties of both HY and phosphide was destroyed with the aluminum phosphates formation, which reduced the HDS activities for catalysts.

	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:Biomaterials may be defined as designed materials, which are used in contact and interact with tissue, blood, cells, proteins and any other living substance. The recent developments and applications of polymeric biomaterials in the field of drug delivery and tissue engineering were reviewed. The review suggests a potential future for biomaterials in the pharmaceutical, biomedical and biological fields.
