Title:
スラリー反応器への触媒小粒子の添加
Document Type and Number:
Japanese Patent JP4422912
Kind Code:
B2
Abstract:
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.
