This invention provides brominated sorbent compositions which are brominated inorganic sorbents having about 0.5 wt % to about 20 wt % bromine therein, based on the total weight of the brominated inorganic sorbent. Methods for preparing brominated sorbent compositions are also provided, as are methods for reducing mercury emissions employing brominated sorbents. In the methods for preparing the brominated inorganic sorbents, the bromine source is elemental bromine and/or hydrogen bromide.
摘要:
A process for preparing a catalyst is disclosed. The process generally comprises the steps of: (a) preparing a slurry comprising clay, zeolite, a sodium-free silica source, quasi-crystalline boehmite, and micro-crystalline boehmite, provided that the slurry does not comprise peptized quasi-crystalline boehmite; (b) adding a monovalent acid to the slurry; (c) adjusting the pH of the slurry to a value above about 3, and (d) shaping the slurry to form particles. This process results in attrition resistant catalysts with a good accessibility.
