    • A method for preparing a catalyst that involves continuously supplying a first stream containing a solvent, one or more metal precursors, and one or more support materials, and a second stream containing at least one reducing agent and/or precipitating agent. The first and second streams are combined to form a combined stream. In one embodiment, the combined stream may be fed to a mixing vessel. In another embodiment, the streams are combined in a mixing vessel. After the streams are combined, one or more metal precursors is reduced or precipitated within the pores of the one or more support materials. Thereafter, solids are separated from the combined stream and processed to produce the supported metal, mixed-metal, metal oxide, or mixed-metal oxide catalyst. In another embodiment, ceramic or metallic monoliths may be coated with the catalytic material after the stream combination and before or after the solid separation and subsequent processing.
    • 一种制备催化剂的方法,所述催化剂包括连续供应含有溶剂的第一物流,一种或多种金属前体和一种或多种载体材料,以及含有至少一种还原剂和/或沉淀剂的第二物流。 第一和第二流被组合以形成组合流。 在一个实施例中,组合的流可以被供给到混合容器。 在另一个实施方案中,将流合并在混合容器中。 在流合并后,一种或多种金属前体在一种或多种载体材料的孔隙内还原或沉淀。 此后,将固体与合并的流分离并加工以产生负载的金属,混合金属,金属氧化物或混合金属氧化物催化剂。 在另一个实施方案中,陶瓷或金属整料可以在流组合之后和在固体分离和后续处理之前或之后用催化材料涂覆。
