Abstract
The invention concerns a catalyst carrier comprising a fibre paper impregnated with a slurry comprising silica sol, micro fibres and a filler, wherein said micro fibres have an equivalent average particle size, measured with sedigraph method, from about 200 nm to about 30000 nm and said filler has an average equivalent particle size, measured with sedigraph method, from about 300 to about 10000 nm. The invention further concerns a method of its preparation, a slurry useful therefore, a catalyst comprising such a catalyst carrier and use of the catalyst.

A catalyst carrier comprising a fibre paper impregnated with a slurry comprising silica sol, micro fibres and a filler, wherein said micro fibres have an equivalent average particle size, measured with sedigraph method, from about 200 nm to about 30000 nm and said filler has an average equivalent particle size, measured with sedigraph method, from about 300 to about 10000 nm, and wherein the main part of the fibres in the fibre paper to be impregnated are longer than the micro fibres used in the impregnation slurry.
A catalyst carrier comprising a fibre paper impregnated with a slurry comprising silica sol, micro fibres and a filler, wherein said micro fibres have an equivalent average particle size, measured with sedigraph method, from about 200 nm to about 30000 nm, the average length to diameter ratio of the micro fibres is from about 3:1 to about 40:1, as measured on microscope image, and said filler has an average equivalent particle size, measured with sedigraph method, from about 300 to about 10000 nm.
