Patent DE-4038609-A1 (DE)
Inventor: PICHLER WERNER DR
IPC: C11D3/12
Filed: 1990-12-04
Abstract: The aim of the invention is to develop a granulation process for the production of heavy zeolite granulates. In this process, the amount of liquid used is a less critical factor, thus enabling (co)polymeric carboxylates to be utilized as a dissolved component of the liquid used in the granulation process. This is achieved by using as the liquid a mixture of water, surface-active agents and (co)polymeric carboxylates, the surfactant content in the liquid being at least 10 % by wt.
