Abstract

A study is performed of the effect of the conditions of preparation (the nature and amount of alkali used to hydrate a gibbsite thermal activation product and the amount of nitric acid (acid modulus value) in preparing a moldable paste) on the properties of aluminum oxide desiccants. A desiccant is obtained that has higher dynamic capacity (more than 10.0 g/100 g) at close specific surface values of around 300 m²/g and higher static capacity (20–22 g/100 g) than foreign and Russian analogues. The desiccant has high strength of more than 8.0 MPa. Such a desiccant can improve the productivity of existing adsorbers and reduce the cost of sorbent regeneration, which is of undoubted practical interest.

高性能氧化铝干燥剂

摘要

研究了制备条件（水合三水铝石热活化产物所用的碱的性质和量以及制备可模塑糊剂中硝酸的量（酸模量值））对氧化铝性能的影响。干燥剂。与国外和俄罗斯类似物相比，干燥剂在接近300 m ² / g的比表面积时具有更高的动态容量（大于10.0 g / 100 g）和更高的静态容量（20-22 g / 100 g）。干燥剂具有大于8.0 MPa的高强度。这样的干燥剂可以提高现有吸附器的生产率并降低吸附剂再生的成本，这无疑是实用的。
