Abstract (en)
[origin: WO9210559A1] 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.
