Silicon-based catalyst carrier for hydrogenation and preparation method thereof

The invention relates to the technical field of catalyst preparation, in particular to a silicon-based catalyst carrier for hydrogenation, which is prepared from the following raw materials: nano silicon dioxide, Al2O3 and silica sol, the silica sol contains 20-30% of silicon, and the particle size of the silica sol is 10-20nm. The invention also provides a preparation method of the silicon-based catalyst carrier for hydrogenation. The catalyst product prepared by the catalyst scheme product is high in density, good in activity and high in strength, and cannot be crushed and pulverized in the use process. Compared with other active metals, the adopted raw materials are low in price, the cost advantage is large, and the profit margin can be greatly improved. 本发明涉及催化剂制备技术领域，尤其是一种加氢用硅基催化剂载体，其原料的配方由纳米二氧化硅、Al2O3、硅溶胶组成，所述的硅溶胶内含硅20％-30％，且粒径10-20nm。本发明还提供了一种加氢用硅基催化剂载体的制备方法。该催化剂方案产品制备的催化剂产品密度大，活性好，强度高，使用过程中不会出现破碎和粉化的情况。采用的原材料相比较其他活性金属价格低，成本优势比较大，可大幅度提高利润空间。
