The known process for preparing the catalyst from kaolin comprises the steps of separating clay and impurities, mixing the clay and the impurities with a dispersant, pulping, desanding, stirring, bleaching (concentrated sulfuric acid and sodium hydrosulfite), washing, filter pressing and dehydrating, and obtaining the finished product. The finished product must not exceed a certain value for the iron element.
The iron removal process in the prior art mainly focuses on two procedures of sand removal and washing. The sand removal is to add a dispersing agent into the ore pulp to separate soil and sand in the kaolin ore more quickly and efficiently, and the sand (including iron sand) is removed under the action of gravity to obtain the kaolin ore pulp; in bleaching, the acid solution dissolves iron or iron oxides. However, in a part of ferroferric oxide enriched area, there is a case that the collected kaolin is purified: because the kaolinite in the kaolin has plasticity, wet soil can be molded into various shapes without being broken, and can be kept unchanged for a long time, the periphery of a small amount of ferroferric oxide particles is wrapped by the kaolinite, the ferroferric oxide particles can not fall off under the action of gravity due to the magnetic adsorption of the ferroferric oxide particles on the side wall of equipment (stainless steel) during sand removal, and enter washing equipment along with slurry, because the kaolinite at the periphery of the ferroferric oxide particles can not be completely removed by the existing washing equipment, and the part of ferroferric oxide can not be dissolved by an acid solution during washing.
