Abstract: Provided are an oxygen-vacancy-rich MoOx/ZrO2 catalyst and a preparation method and its application in hydrodeoxygenation of a biomass gas-solid system. The method includes the following steps: (1) dissolving zirconyl nitrate and ammonia water in de-ionized water respectively and then mixing fully and performing aging, cooling, filtering, washing and drying to obtain a solid powder and calcining the solid powder to obtain ZrO2 solid; (2) adding ammonium molybdate tetrahydrate into de-ionized water for dissolution, stirring and dropwise adding into the ZrO2 solid, and mixing to make loading uniform, and then drying to obtain a solid, and then grinding and calcining the solid to obtain MoOx/ZrO2 powder; (3) adding a Pt precursor into de-ionized water for dissolution, and dropwise adding into the MoOx/ZrO2 powder and stirring to make loading uniform, and then drying to obtain a solid, and then grinding and calcining the solid to obtain the Pt—MoOx/ZrO2 catalyst.

Abstract: An apparatus (40) for forming a profiled article (46) comprises: a forming path (41) through which a blank of deformable material to be formed into the profiled article passes; a pair of complementary and opposing body forming die members (45, 45?) adapted to travel along the forming path (41); and a drive (44, 44?) that facilitates travel of the body forming die members (45, 45?) along the forming path (41), wherein the pair of body forming die members (45, 45?) is adapted to act on the blank of deformable material independently to form a desired profile on the blank. Locating elements (75) that locate the blanks may be provided. A method of forming material is also provided. Further, there is provided a length of deformable material for use with the apparatus.
