Abstract
A process is disclosed for producing a sheet for a catalyst carrier for vapor-phase reactions which comprises mixing highly heat resistant ceramic fibers, organic fibers and an organic binder to form a slurry, forming the slurry into a paper sheet, impregnating the paper sheet with a silicon compound, converting the silicon compound to silica gel and heating the impregnated sheet to burn up the organic fibers and organic binder. The process produces an improved catalyst carrier for vapor-phase reactions having high porosity and good strength properties.
