20120258855PROCESS FOR MANUFACTURING A CATALYST SUPPORT AND A CATALYST - The invention relates to a process for manufacturing a catalyst support, in which one or more fibres are fed into a mould, said fibre having a diameter in the range of 5-300 microns, and a length over diameter ratio greater than 500. The body in the mould is compressed and then contacted with a mixture comprising a liquid and a carrier material. The liquid is removed from the wetted body to provide a catalyst support comprising an entangled fibre and carrier material. A catalyst can be made using the same process and additionally adding a catalytically active metal with the mixture comprising a liquid and a carrier material. Alternatively a catalyst can be made using the process for manufacturing a catalyst support followed by impregnation with a catalytically active metal.10-11-2012
