Paolasini, S

A monolithic support for a catalyst suitable for use in controlling carbon monoxide emission is prepared by forming a homogeneous, fluid semi-solid mass by admixing colloidal gamma alumina, alpha alumina monohydrate and ceramic fibres with fluidizing and binding agents, water and a mineral acid, said acid being used in an amount sufficient to convert said alpha Al/sub 2/O/sub 3/ monohydrate into a gel, forming the mass into a body of the desired shape, drying the body to substantially remove the added water, at least 10% of said added water being removed at a temperature lower than 50/sup 0/ C., and heat-treating the dried body at 800/sup 0/-1000/sup 0/ C.
