Small particle size catalysts having an average particle size of less than 20 or 10 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...
[ What is claimed is:] [1.] A slurry hydroprocessing process in which a hydrocarbonaceous feed is reacted with hydrogen in the presence of a particulate hydroprocessing catalyst dispersed in a slurry comprising a hydrocarbonaceous liquid and said particles, to which is added fresh or regenerated particles of said catalyst having an average particle size less than 20 microns, wherein said particles are contacted with one or more liquid, non-acidic polar oxygenates to form a mixture comprising said particles and said oxygenates and said mixture is added to...
