    摘要： The use of base/clay composites materials as sorbents for the removal of SO.sub.2 and SO.sub.3 (SO.sub.x) from flue gas and other sulfur containing gas streams is described. The base is either an alkaline earth metal carbonate (eg. CaCO.sub.3) or hydroxide (eg. Ca(OH).sub.2) is incorporated onto the clay by precipitating from corresponding metal oxide (eg. CaO) in an aqueous clay slurry. A second metal oxide or oxide precursor, preferably selected from transition metal ions, capable of promoting the oxidation of sulfur dioxide to sulfur trioxide, is incorporated to the base/clay composite during the synthesis in the form of finely divided metal oxide powder, metal oxide sol, water soluble metal salt or as clay-intercalated metal cation. The use of clay as dispersing agent for both the basic oxide and the second metal oxide component decreases the particle agglomeration of base particles and increases the rate of SO.sub.x uptake compared to the bulk bases in current use.

    摘要： The preparation and the use of base/clay composites materials as sorbents for the removal of SO.sub.2 and SO.sub.3 (SO.sub.x) from flue gas and other sulfur containing gas streams is described. The base is either an alkaline earth metal carbonate (e.g. CaCO.sub.3) or hydroxide (e.g. Ca(OH).sub.2) and is incorporated onto the clay by hydrating a dry physical mixture of an alkaline earth metal oxide, a smectite clay and a second metal oxide, or metal oxide precursor to form a powdered composite material. The second metal oxide, preferably selected from transition metal ions, act as an oxidation catalyst for the conversion of sulfur dioxide to sulfur trioxide. The use of clay as dispersing agent for both the basic oxide and the catalytic oxide component decreases the particle agglomeration of base particles and increases the rate of SO.sub.x uptake compared to the bulk bases in current use.

    摘要： A process for preparing a stable pillared layered lattice clay, comprising the steps of preparing a hydrolyzed solution of ferric ion by reacting a solution of a salt of the said metal with a base at temperatures in the range of 22.degree. to 28.degree. C. and aging the solution within said temperature range to develop the hydrolyzed pillaring agent, contacting an aqueous slurry of a layer lattice clay selected from the group consisting of smectites, vermiculite, and flurohectorite, with said hydrolyzed solution, and recovering the intercalated pillared clay product. The resultant pillared clay product has a unit clay cell containing from 6.1 to 9.8 ferric ions per cell, and has a repeating spacing of from about 22 to 28 Angstroms. The product is particularly useful in catalyzing conversion processes such as the well-known Fischer-Tropsch process.

    摘要： Polymer composite membranes containing mesoporous particles which function in part as reinforcing agents, modifiers of polymer surface polarity, and membrane structure modifiers are provided. The composites provide superior resistance to internal damage and pore compaction, increased permeability to water with retention of separation fidelity, and resistance to chemical degradation and mechanical wear, along with minimal shedding of the reinforcing particles under applied pressure. These improvements in properties are particularly desirable for the water purification by membrane filtration methods.
