Abstract
This disclosure is concerned with a novel limp, low-pressure-drop catalytic mat, particularly adapted for use in ignitible gas-flow systems, such as heated hair curlers and the like, comprising in preferred form a loosely packed quartz fiber mat to the fibers of which have been adhered oxide particles as of alumina and the like, coated with platinum catalytic particles, without, however, impairing the limpness, looseness and flexibility of the mat.
Claims21
A low pressure-drop catalytic structure comprising a limp, loosely packed, inorganic fibrous, relatively low surface area porous mat to the fibers of which, throughout the mat, non-volatile relatively high surface area metal oxide particles have been adhered and upon which noble metal catalytic material has been coated.
A method of preparing a low pressure-drop incombustible catalytic structure adapted for catalytic oxidation of a gaseous fuel in air, that comprises, applying metal oxide particles particles to and throughout a limp, loosely packed relatively low surface area porous mat of inorganic fibers;
- heat-drying the metal oxide particles to bond the same to the fibers as a relatively high surface area coating throughout the mat;
- and applying platinum material to coat the metal oxide particles and catalyze the same throughout the mat.
