    摘要: The present invention is directed to an improved apparatus and method of minimizing catalyst poisoning from exhaust gas streams containing inorganic deposits and particulate matter. More specifically, the present invention is directed to an upstream metallic foam trap and a downstream monolithic precious metal catalyst, wherein the trap physically blocks inorganic deposits and particulate matter from poisoning the downstream catalyst. The present invention is also directed to a metallic foam trap containing a coat comprising a first metallic thermal arc sprayed layer and optionally a second refractory metal oxide.

    摘要: The present invention is directed to an improved apparatus and method of minimizing catalyst poisoning by inorganic deposits from lube oil additives and particulate matter, especially in aircraft. More specifically, the present invention is directed to an air purification system comprising an upstream metallic foam trap and downstream converter, wherein the trap physically blocks inorganic deposits and particulate matter from poisoning the downstream catalysts. The present invention is also directed to a metallic foam trap containing a coat comprising a first metallic thermal arc sprayed layer and optionally a second refractory metal oxide.

    摘要: A low-cost catalytic article is provided for treating gaseous fluid streams such as exhaust streams from gasoline-powered engines. The articles contain residence chambers defined by chamber walls and foraminous catalytic elements that contain a catalyst composition for converting a reactant contained in the fluid stream, and deflectors, which increase the residence time of the fluid stream in the residence chamber and the contact time of the fluid stream with the catalytic element.

    摘要: A coated metal substrate useful for carrying an exhaust emission treatment catalyst such as a three-way conversion catalyst for use with small engine platforms. The coated metal substrate comprises a metal such as a stainless steel, a carbon steel, a FeCr alloy, HASTELLOY® and the like. The coating on the metal substrate comprises an alumina silicate having alumina particles impregnated therein. The coating is applied using a liquid dispersion containing an aluminum silicate and the alumina particles are dispersed into the aluminum silicate coating while the coating is still wet. The coated metal substrate is then calcined. Thereafter, a washcoat containing an engine exhaust treatment catalyst may be applied to the surface of the coated metal substrate.
