ABSTRACT:
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.degree. C., and heat-treating the dried body at 800.degree.-1000.degree. C.
