Latest Patents
Kunkel holds a patent for a ceramic honeycombed elongated catalyst carrier and the method for its production. This ceramic catalyst carrier features a honeycombed structure with multiple elongated parallel channels, preferably square in shape, and thin, porous walls. The walls have a thickness ranging from 0.4 mm to 1.2 mm. The open cross-sectional area of the channels exceeds 80% of the total cross-section of the carrier body. The design aims for low primary porosity while also incorporating secondary porosity to enhance the active surface for the catalyst. The pores in the secondary porosity exhibit a specific size distribution curve, with a modal value between 4,000 nm and 60,000 nm. The total true porosity of the ceramic is ideally between 50 and 70 Vol. %. The ratio of total to secondary porosity is maintained between 1:1 and 6:1. The mechanical strength of the thin walls is improved using ceramic fibers. The production process involves mixing compounds to achieve desired plasticity, aging, extruding to form the honeycombed structure, and subsequently drying and firing it.
