Preparation method of macroporous alumina and spherical-cavity-shaped macroporous alumina
The invention discloses a preparation method of macroporous alumina and spherical-cavity-shaped macroporous alumina. The preparation method of the macroporous alumina comprises the following steps: uniformly mixing an aluminum source, soluble sugar, polyol, amide, polyethylene glycol and a solvent at 10-40 DEG C, then adding a coagulant, and uniformly mixing to obtain gel; carrying out aging treatment on the gel, eluting the aged material, and drying and roasting the solid phase to obtain macroporous alumina; wherein the solvent is low-carbon alcohol and/or water; the viscosity average molecular weight of the polyethylene glycol is 50,000-200,000; the coagulant is pyridine and/or ethylene oxide. The method disclosed by the invention is simple in preparation process, green, environment-friendly and easy for industrial production, and the obtained spherical-cavity-shaped macroporous alumina is suitable for preparing a carrier of a heavy residual oil hydrotreating catalyst.
本发明公开了一种大孔氧化铝的制备方法及球腔状大孔氧化铝。本发明的大孔氧化铝的制备方法，包括如下内容：在10‑40℃下，将铝源、可溶性糖、多元醇、酰胺、聚乙二醇和溶剂混合均匀，然后加入促凝剂，混合均匀得到凝胶；凝胶进行老化处理，老化后的物料进行洗脱，固相进行干燥、焙烧，得到大孔氧化铝；其中所述的为低碳醇和/或水；聚乙二醇的粘均分子量为5~20万；所述的促凝剂为吡啶和/或环氧乙烷。本发明方法制备过程简单、绿色环保、易于工业生产，得到的球腔状大孔氧化铝适用于制备重渣油加氢处理催化剂的载体。
