Title:
ゼオライトを含有する固体の製造方法
Document Type and Number:
Japanese Patent JP4406606
Kind Code:
B2
Abstract:
In a process for concentrating an at least partially crystalline solid containing at least one zeolite in a mixture comprising at least one auxiliary, for example a template compound, and said solid, the mixture is ultrafiltrated in a step (II) to divide the mixture into a retentate and a permeate, the solids content in the retentate being higher than that in the mixture and the solids content in the permeate being lower than that in the mixture. This procedure allows auxiliaries, in particular template compounds, present in the permeate to be recycled into a crystallizing step (I) upstream of step (II).
