    摘要： A vessel arrangement having a base and multiple vessels suited for simultaneously conducting a plurality of isolated experimental reactions or treatments at atmospheric process conditions or elevated temperatures and pressure condition has been developed. A component of a first material is introduced into one independent vessel through an opening in its top of the first vessel and another component of a second material is introduced into a different independent vessel through its top. Both vessels are removably located about a base at different first locations. Transformation of the components in the vessels then occurs to produce different materials therein. After completion of the experiments a displacement medium simultaneously urges the vessels from their respective locations about the base for discard or reuse after any necessary cleaning. Typically at least one property of the materials from the vessels is determined either within the vessel or after recovery of the materials.

    摘要： A process for preparing catalysts has been developed. The process involves the use of a chelating ligand such as ethylenediaminetetraacetic acid. The aqueous solution of the chelating ligand and a promoter metal salt is first prepared heated to a temperature of about 80.degree. C. to about its boiling point and then combined with an aqueous solution containing a Group VIII metal compound. Next this mixed solution is aged at a temperature of about 40.degree. C. to about 100.degree. C. and then used to impregnate a support, e.g., alumina spheres. The impregnated support is then dried, calcined and reduced with hydrogen. Prior to reduction the catalyst may optionally be treated with a chlorine or chloride stream.

    摘要： This invention relates to a catalytic composite for treating an exhaust gas comprising a support which is a refractory inorganic oxide having dispersed thereon lanthanum, at least one other rare earth component and at least one noble metal component selected from the group consisting of platinum, palladium, rhodium, ruthenium and iridium. An essential feature of said catalytic composite is that the lanthanum be present as crystalline particles of lanthanum oxide which have an average crystallite size of less than about 25 Angstroms. The support may be selected from the group consisting of alumina, silica, titania, zirconia, aluminosilicates and mixtures thereof with alumina being preferred. Illustrative of the other rare earth components are cerium, neodymium, praeseodymium, dysprosium, europium, holmium and ytterbium. An important feature in manufacturing the catalytic composite is the dispersion of lanthanum oxide onto said refractory inorganic oxide support. In a specific example, lanthanum may be dispersed on alumina as follows. A solution of a lanthanum salt is mixed with a hydrosol of aluminum, particles are formed from said lanthanum containing hydrosol, calcined to form an inorganic oxide particle containing lanthanum oxide, ground to give a powder of alumina containing finely dispersed lanthanum oxide. This powder in turn can be mixed with another rare earth oxide such as cerium oxide to a slurry which in turn is used to coat a solid monolithic carrier. Finally, at least one noble metal component is dispersed on said coated solid monolithic carrier.
