2021-2-27 · This research were carried out by FeCrAl substrate material and γ-Al 2 O 3 coating material. Those material was performed by ultrasonic bath technique to embed the γ-Al 2 O 3 into FeCrAl substrate. Ultrasonic bath was conducted to FeCrAl foil which cut in size of 40 mm x 20 mm and γ-Al 2 O 3 powder. The samples were cleaned in water and

2013-9-15 · The FeCrAl (FeCralloy ®) is an appropriate material to be used as catalytic support because it can form a thin superficial alumina film . This type of substrate has been employed for the in situ growth of crystalline zeolite coatings [12], [13] and also for the preparation of zeolite-based structured catalysts with millimetric ...
2021-9-23 · The use of platinum group metal catalysts supported on ceramic monoliths for control of gaseous emissions from automobiles and chemical plant is now well established. Research in the Johnson Matthey Laboratories and at AERE Harwell, aimed at meeting the demand for more effective catalysts, has resulted in a new generation of platinum catalysts in which the ceramic substrate .
2021-10-21 · Overview of Metal Honeycomb Metal honeycomb substrates used in catalytic converters are made from extremely thin metal foil, typically with a thickness of just 0.05mm. By comparison the walls of a ceramic substrate may be four times thicker. For this reason, metal substrates offer less resistance to gas flow and therefore can accommodate a
application of foil washcoating is in the manufacturing of metallic micro and monolithic reactors. EXPERIMENTAL Pretreatment of Substrates FeCrAl foils (Fe 72%, Cr 23% and Al 5%) were used as the substrates for alumina washcoatings. The foils were immersed in an ultrasonic bath of a hot solution of detergent and water for cleaning and removing

2021-8-28 · The metallic catalyst "substrates" are made of a thin, specialty alloy metal foil called FeCrAlloy. The foil is assembled, flat and corrugated alternating side by side, to form a honeycomb structure. Similar to ceramic monoliths, the assembled foils form cells or parallel channels that allow exhaust gases to run axially through the catalyst.
