ADICAO DE PARTICULAS CATALISADORAS PEQUENAS A UM REACTOR DE LAMAS

Small particle size catalysts having an average particle size of less than 20 or 10 µm (microns), which agglomerate when contacted with a hydrocarbon liquid, are easily dispersed in the hydrocarbon liquid by first forming a mixture comprising the catalyst particles and one or more non-acidic, liquid...

More Information
Summary:Small particle size catalysts having an average particle size of less than 20 or 10 µm (microns), which agglomerate when contacted with a hydrocarbon liquid, are easily dispersed in the hydrocarbon liquid by first forming a mixture comprising the catalyst particles and one or more non-acidic, liquid polar oxygenates, such as an alcohol, ketone, ester, ether or mixture thereof. The mixture is contacted with the hydrocarbon liquid in which the particles then readily disperse. This process is useful for adding fresh or regenerated small particle size catalyst to catalytic hydroprocessing process slurries.
