Method for filling a chamber with a bed of variable density particles

用可变密度式微粒床层装填容腔的方法

Abstract

The invention concerns a method for filling a chamber with a granular solid material at an adjustable loading density, comprising the following steps: (a) filling said chamber with a first granular solid material (A) and a solid diluent (B) which a second granular solid material having different solubility properties from the first granular solid material (A); and (b) removing completely the solid diluent (B) and leaving in the chamber only the first granular solid material (A), by passing through the fixed bed deposited at step (a) a solvent having null dissolving power for the first granular solid material (A) and a high dissolving power for the second granular solid material (B).
本发明涉及利用粒状固体材料以可调节装料密度的方式装填容腔的方法,所述方法包括以下步骤,所述步骤在于:(a)用一第一粒状固体材料(A)和一固态稀释剂(B)的混合物装填所述容腔,所述固态稀释剂是一第二粒状固体材料,其溶解度性能不同于所述第一粒状固体材料(A);和(b)通过使一溶剂经过在所述步骤(a)中沉积的所述固定床,而消除所有的所述固态稀释剂(B)并在所述容腔中只留下所述第一粒状固体材料(A),其中所述溶剂对于所述第一粒状固体材料(A)没有溶解能力,而对于所述第二粒状固体材料(B)具有高溶解能力。
