Solid particle containing active carbon, support and catalyst |
摘要 |
Solid particles which comprise a substantially homogeneous mixture of an active carbon and an attrition-resistant inorganic substance and which have an average particle size of smaller than 300 mu m. The average particle size is preferred to range from 20 to 200 mu m. The inorganic substance is, for example, silica, titania, zirconia, alumina or silica-alumina. The active carbon is preferred to be contained in an amount of 5 to 70% by weight. The solid particles can be produced by spray drying a slurry containing an active carbon or a precursor thereof and an attrition-resistant inorganic substance or a precursor thereof so that particles having an average particle size of smaller than 300 mu m are obtained, and calcining the particles. The inorganic substance or precursor thereof is preferably present in a colloidal or hydrogel state in the slurry. The particles are excellent in attrition resistance and mechanical strength. A catalyst support and a catalyst comprising the solid particles are also disclosed.
